Swiss courts use the two-step method with surplus distribution mandated by the Federal Supreme Court (ATF 147 III 265). First, all incomes and needs are calculated, then any surplus is distributed using the large and small heads rule.
Child costs are based on the official Zurich table: Ages 0-4: CHF 1,320/month, Ages 5-12: CHF 1,575/month, Ages 13-18: CHF 1,920/month. These include housing, food, clothing, insurance, and recreation.
Since 2017, Swiss law compensates the custodial parent for reduced earning capacity due to childcare. This is separate from child support and recognizes the economic value of personal care.

Swiss Alimony and Child Support Calculator: Complete Guide to Maintenance Calculations in Switzerland
Navigating divorce or separation in Switzerland involves understanding a complex system of maintenance payments that protect both children and former spouses. The Swiss Federal Supreme Court has established a standardized two-step calculation method with surplus distribution, creating consistency across all 26 cantons for determining child support (Kindesunterhalt) and spousal maintenance (Ehegattenunterhalt). This comprehensive guide explains the legal framework, calculation methodology, and practical considerations for anyone facing these important financial decisions in Switzerland.
Understanding Swiss maintenance law is essential because the amounts involved significantly impact household budgets for years or even decades. Child support obligations typically continue until age 18 or completion of first professional training, while spousal maintenance depends on whether the marriage had a formative effect on the dependent spouse's life. Our calculator applies the official two-step method used by Swiss courts, providing reliable estimates based on the Zurich Child Cost Table and Federal Supreme Court guidelines.
Understanding the Swiss Two-Step Maintenance Calculation Method
Since landmark decisions by the Swiss Federal Supreme Court in 2020 and 2021, all Swiss cantons must apply the same calculation methodology for determining maintenance payments. This two-step method with surplus distribution (Zweistufige Methode mit Überschussverteilung) replaced the previous patchwork of cantonal approaches that created significant inconsistencies across Switzerland. The standardization ensures fair treatment regardless of where divorce proceedings occur.
The first step involves determining available financial resources by calculating the net income of both parents. This includes not only base salary but also commissions, bonuses, and other regular payments received over several years. The court may also impute hypothetical income if a parent is not working to their full capacity. Simultaneously, the needs of each family member are calculated based on the minimum living standard under debt enforcement law (betreibungsrechtliches Existenzminimum).
If financial means allow, maintenance extends beyond the basic minimum to the family law minimum living standard (familienrechtliches Existenzminimum). This higher standard includes telecommunications expenses, private insurance premiums, education costs, private pension contributions, taxes, and savings. The court only considers expenses that are actually paid and regular in nature. Any surplus remaining after covering these expanded needs is distributed among family members.
The Large and Small Heads Rule for Surplus Distribution
When calculating how to distribute surplus income after covering basic needs, Swiss courts apply the Grosse und kleine Köpfe (large and small heads) rule. Under this principle, each parent counts as a large head worth two shares, while each minor child counts as a small head worth one share. Adult children are not included in this distribution calculation.
The surplus portion allocated to children covers extracurricular activities, leisure pursuits, pocket money, and family vacations. This rule may be adapted according to specific circumstances, such as children with special needs or significantly different custody arrangements. The court retains discretion to adjust distributions when standard application would produce unfair results.
Child Support Components in Switzerland
Swiss child support (Kindesunterhalt) consists of two distinct components that together ensure the child's complete financial needs are met. The first component is cash support (Barunterhalt), which covers direct living costs including food, clothing, accommodation, health insurance, education, recreation, and transportation. The second component is care support (Betreuungsunterhalt), introduced in 2017 to compensate the custodial parent for lost earning capacity due to childcare responsibilities.
The 2017 revision to Swiss maintenance law (Art. 285 para. 2 ZGB) introduced Betreuungsunterhalt to protect parents who reduce their working hours to care for children. This component acknowledges that the caregiving parent provides value through in-kind support, not just the parent making cash payments.
According to the Swiss Civil Code Article 276, both parents share equal responsibility for their child's maintenance. The custodial parent typically fulfills their obligation through in-kind contributions by personally caring for the child, while the non-custodial parent provides financial support. In shared custody arrangements, if parents have equivalent incomes, costs are split equally and no support payment is required. When income disparity exists, the higher-earning parent contributes more financially regardless of their caregiving time.
The Zurich Child Cost Table Explained
The Zurich Child Cost Table (Zürcher Kinderkosten-Tabelle), published annually by the Department of Education of the Canton of Zurich, serves as the primary reference for estimating children's living costs throughout Switzerland. This statistical grid determines average monthly costs for maintaining a child based on their age group, providing a starting point for maintenance calculations.
The table breaks down costs into specific categories: accommodation typically accounts for CHF 520-565 monthly, food ranges from CHF 280-350 depending on age, clothing costs approximately CHF 100-125, and health insurance premiums average CHF 100-115. Additional costs for recreation, transportation, and personal items increase significantly during teenage years when children develop more expensive needs while not yet earning their own income.
Important to note is that these figures represent averages and may vary by canton. Higher-income families are expected to provide proportionally higher support, as Swiss law aims to maintain children at the standard of living they would have enjoyed had the family remained together. Courts consider the actual lifestyle and financial capacity of both parents when determining final amounts.
Minimum Living Standards in Swiss Maintenance Law
Swiss maintenance calculations recognize two tiers of minimum living standards that protect different interests. The debt enforcement minimum (betreibungsrechtliches Existenzminimum) represents the absolute floor below which a debtor's income cannot be garnished. According to the Conference of Debt Enforcement and Bankruptcy Officials, this amount is CHF 1,200 monthly for a single person, CHF 1,350 for a single parent, and CHF 1,700 for couples.
The family law minimum (familienrechtliches Existenzminimum) sets a higher standard that includes additional legitimate expenses. This expanded calculation covers the basic needs plus telecommunications costs, private insurance premiums beyond mandatory coverage, continuing education expenses, pension fund contributions, and regular debt payments. When both parties can maintain this higher standard, courts apply it rather than the bare minimum.
When resources are insufficient to cover all needs, Swiss law establishes clear priorities: minor children's maintenance comes first, followed by care support for the custodial parent, then any marital or post-marital spousal maintenance, and finally maintenance for adult children still in education.
Spousal Maintenance After Divorce
Swiss spousal maintenance (Ehegattenunterhalt) underwent significant changes following Federal Supreme Court rulings in 2020 and 2021. The fundamental principle now emphasizes a clean break (Scheidungsunterhalt), meaning both spouses should ideally manage their economic situations independently after divorce. Maintenance is only awarded when self-sufficiency is impossible or unreasonable given the circumstances.
The critical question is whether the marriage had a formative effect (lebensprägend) on the dependent spouse's life. Previous automatic assumptions have been eliminated: having children, marriage duration exceeding ten years, or reaching age 45 while unemployed no longer automatically establish a formative marriage. Courts now examine each case individually, considering how the marriage actually shaped each spouse's career trajectory and earning capacity.
When spousal maintenance is awarded, the amount typically ensures the dependent spouse can maintain the marital standard of living, but cannot exceed what they would have enjoyed during marriage. The paying spouse's ability to provide must also be considered, and their own minimum living standard cannot be violated. Maintenance terminates upon remarriage of the recipient, death of either party, or end of a specified time period.
Calculating Net Income for Maintenance Purposes
Accurate income calculation forms the foundation of any maintenance determination. Swiss courts consider net income after mandatory deductions including AHV/IV/EO contributions (old age, disability, and loss of earnings insurance), unemployment insurance, accident insurance, and pension fund contributions (BVG). Income tax is typically calculated separately as part of the family law minimum needs.
Beyond base salary, maintenance calculations include all regular income sources: commissions, bonuses, profit sharing, rental income, investment returns, and any other recurring payments received over several years. Irregular bonuses may be averaged over three to five years to determine a representative amount. Self-employed individuals require particular scrutiny, with courts examining business accounts to determine sustainable income levels.
Courts may impute hypothetical income when a parent is voluntarily underemployed or unemployed. If a parent could reasonably earn more given their education, experience, and the job market, the court may calculate maintenance based on that potential rather than actual earnings. This prevents strategic income reduction.
Custody Arrangements and Their Impact on Support
Switzerland recognizes joint parental authority (gemeinsame elterliche Sorge) as the default arrangement, but physical custody can vary significantly between parents. The custody arrangement directly affects maintenance calculations because the parent providing more direct care fulfills part of their maintenance obligation through in-kind contributions rather than cash payments.
In alternating custody arrangements (alternierende Obhut) where children spend roughly equal time with both parents, maintenance calculations become more complex. If both parents have similar incomes, they may simply share direct costs without requiring formal support payments. However, income disparities still necessitate equalization payments so children experience similar living standards in both households.
Single custody arrangements (alleinige Obhut) result in the non-custodial parent paying the full cash maintenance contribution while the custodial parent provides primarily in-kind support. The non-custodial parent cannot reduce their financial obligation by claiming partial custody credit unless formal alternating custody has been established and approved by the court.
Family Allowances and Their Role in Maintenance
Swiss family allowances (Familienzulagen) provide additional support for families with children. The minimum federal standards require at least CHF 215 per month per child as family allowance (Kinderzulage) and at least CHF 268 per month for children aged 16-25 in education as education allowance (Ausbildungszulage). Many cantons provide higher amounts, with some reaching CHF 300 or more per child monthly.
These allowances are typically paid to the parent with primary custody and are considered when calculating the overall financial picture. They effectively reduce the net cost that must be covered through maintenance payments. When determining child support amounts, courts factor in the family allowance the receiving parent will obtain, adjusting the maintenance payment accordingly to avoid double-counting.
Tax Implications of Maintenance Payments
Swiss tax law treats maintenance payments as taxable income for the recipient and deductible expenses for the payer. Child support received must be declared as income by the custodial parent, who in turn can claim family-related tax deductions. The paying parent deducts the full maintenance amount from their taxable income but cannot claim child-related deductions.
This tax treatment affects the net impact of maintenance on both households. A CHF 1,000 monthly maintenance payment costs the payer less than CHF 1,000 after tax deduction, while the recipient receives less than CHF 1,000 after paying tax on the income. Financial planning should account for these effects to ensure the maintenance amount achieves its intended purpose of maintaining appropriate living standards.
The custodial parent claiming maintenance can deduct up to CHF 6,800 per child per year for federal taxes as a child deduction, plus up to CHF 25,800 per child per year for external childcare costs. Cantonal deductions vary. The parent paying maintenance loses these deduction benefits.
Modification and Enforcement of Maintenance Orders
Maintenance orders are not permanent and can be modified when circumstances change significantly. Either parent can petition the court to adjust payments if there are substantial changes in income, employment, health, or custody arrangements. The burden of proof lies with the party seeking modification to demonstrate that changed circumstances warrant a new calculation.
When a maintenance debtor fails to pay, Swiss law provides robust enforcement mechanisms. The creditor can initiate debt collection proceedings through the local Betreibungsamt (debt enforcement office), request wage garnishment through a debtor's order (Schuldneranweisung) that compels employers to pay directly to the creditor, or seek criminal prosecution for willful non-payment. Cantons also offer collection assistance and maintenance advances to bridge gaps during enforcement.
Duration of Child Support Obligations
Under Article 277 of the Swiss Civil Code, parents must support their children until they reach majority at age 18. However, the obligation extends beyond majority if the child has not yet completed an appropriate first education, provided this education is completed within a reasonable timeframe and circumstances reasonably permit continued support.
This extended obligation commonly applies to university students, apprentices, and those pursuing vocational training. Courts generally expect children to complete their first professional qualification before parental support ends. A medical student, for instance, might receive support into their mid-twenties, while an apprentice typically completes training by age 19 or 20. The obligation ends when the child can reasonably support themselves through employment.
Practical Steps for Calculating Maintenance
To estimate maintenance obligations, gather comprehensive financial documentation including tax returns, salary statements, bank statements, and documentation of all regular expenses. Calculate net income for both parents after mandatory deductions. Determine the children's costs using the Zurich Child Cost Table as a baseline, adjusted for your specific family circumstances.
Next, establish each person's minimum living needs including housing costs, health insurance premiums, transportation expenses, and basic needs allowance. Compare total family income against total family needs to determine if surplus exists. If so, apply the large and small heads rule to distribute the surplus fairly among all family members.
Family with two children ages 8 and 14: Father earns CHF 8,000 net monthly, mother earns CHF 4,500 net monthly. Combined income: CHF 12,500. Children's costs: CHF 1,575 + CHF 1,920 = CHF 3,495. Parents' minimum needs: CHF 2,800 + CHF 2,400 = CHF 5,200. Total needs: CHF 8,695. Surplus: CHF 3,805. Using large and small heads (2+2+1+1=6 shares): Each child receives approximately CHF 634 of surplus, each parent receives approximately CHF 1,268.
Special Considerations for International Families
When divorcing families have international connections, jurisdictional questions become crucial. If both parties have habitual residency in Switzerland, Swiss courts have jurisdiction. The court in the canton of either spouse's habitual residence can hear the case. For cross-border situations, international treaties including the Hague Convention and Lugano Convention may apply.
Swiss maintenance orders can be enforced internationally through these treaty frameworks. Conversely, foreign maintenance orders may be recognized and enforced in Switzerland under reciprocal arrangements. International families should seek specialized legal advice to navigate the complex interplay of different national laws and ensure maintenance arrangements are enforceable in all relevant jurisdictions.
The Role of Prenuptial and Postnuptial Agreements
While Swiss law allows spouses to regulate spousal maintenance through prenuptial or postnuptial agreements, child support cannot be waived or limited by contract since it belongs to the child, not the parents. Any agreement affecting children's maintenance rights is subject to court approval and must serve the child's best interests.
Spousal maintenance provisions in marital agreements face judicial scrutiny. Courts retain power to modify or reject provisions that are obviously unfair at the time of divorce. The test compares the agreed maintenance against what Swiss law would provide, with courts intervening when agreements produce results that shock the conscience or leave one spouse destitute while the other prospers.
Recent Developments in Swiss Maintenance Law
The 2020-2021 Federal Supreme Court decisions fundamentally reformed Swiss maintenance practice. The emphasis on economic independence after divorce, standardized calculation methodology, and rejection of automatic formative marriage assumptions represent significant shifts from prior practice. These changes particularly affect women who previously could expect lifetime maintenance based solely on marriage duration or having children.
Courts now expect spouses to resume or expand employment after divorce unless specific circumstances make this unreasonable. The age at which reintegration into the workforce is no longer expected has increased, and courts examine whether realistic employment opportunities exist. These developments encourage earlier financial planning during marriage and may influence decisions about career sacrifices for childcare.
Swiss media characterized the 2021 reforms as ending the era when marriage served as life insurance for women. Both spouses are now expected to maintain earning capacity throughout marriage when possible, and the economically weaker spouse should plan for eventual self-sufficiency.
Working with Family Law Professionals
Given the complexity of Swiss maintenance calculations, professional legal advice is highly recommended. Family law attorneys can analyze your specific circumstances, gather appropriate evidence of income and expenses, and advocate for fair treatment in negotiations or court proceedings. Mediation offers an alternative to adversarial litigation, allowing parents to reach agreements that serve everyone's interests.
Specialized family law attorneys in Switzerland often hold certification as family law specialists (Fachanwalt SAV Familienrecht). They understand cantonal variations in practice, have experience with local courts, and can navigate the procedural requirements efficiently. Initial consultations typically allow prospective clients to understand their situation and options before committing to representation.
Financial Planning During and After Divorce
Beyond immediate maintenance calculations, divorce triggers comprehensive financial restructuring. Pension fund assets (BVG) must be divided equally unless spouses agree otherwise. The matrimonial property regime determines how assets accumulated during marriage are split. These divisions, combined with ongoing maintenance obligations, significantly affect long-term financial security for both parties.
Post-divorce financial planning should account for housing costs in separate households, childcare expenses if both parents work, tax implications of maintenance payments, and retirement planning with reduced pension entitlements. Professional financial advisors experienced with divorce situations can help both parties understand their new financial reality and plan appropriately for the future.
