Financial planning: what remains after pay and fixed costs?
A useful financial plan covers the monthly budget, reserves, risks and the next major decisions.
Updated 30 September 2026A financial plan starts with actual cash flow
A financial plan is not a demonstration of how frugally a household could live in theory. It should show where money actually goes, which commitments already exist and what remains for new goals. Start with twelve complete months. Export bank and card transactions, and add cash withdrawals and bills paid from other accounts. Record take-home pay, family allowances, regular side income and any maintenance payments separately. Then list rent or mortgage, health insurance, other insurance, transport, food, childcare, taxes and loan repayments. A household receiving CHF 9,000 net with CHF 6,800 in visible monthly expenses does not automatically have CHF 2,200 free. Annual premiums, holidays, repairs and taxes may use up the apparent difference. Convert every irregular bill into a monthly provision. Mark one-off events such as a move or car purchase separately so they do not distort normal spending. A joint overview helps couples even when each partner keeps separate accounts. The aim is not to give every receipt a perfect label. It is enough for income, expenses, provisions and the actual change in assets to reconcile. Only then can decisions about retirement saving, investment or buying a home rest on a reliable foundation. Review the figures with the people who share the commitments, because a plan that only one partner understands is difficult to maintain.
Do not mix gross pay, take-home pay and tax
An employment contract often states gross salary, while the household budget needs the money actually available. Social insurance contributions and possibly other amounts come out of pay. For some people, tax at source is deducted directly; for others, provisional and final tax bills arrive later. Use real account credits for cash-flow planning and make a separate allowance for tax in your situation. Swiss tax is levied at federal, cantonal and municipal levels. Residence, family circumstances and other details affect the bill. A generic percentage found online may help with a first estimate but is not enough before taking on a mortgage. For example, an employee receives CHF 700 more each month after changing jobs. At the same time, how their tax is collected changes, and a later annual bill may be due. If all CHF 700 is immediately tied to a long-term savings plan, cash may be short when that bill arrives. Before changing standing orders, record the new take-home pay, estimated annual tax and advance payments already made. Compare these with the last tax assessment or a current cantonal calculation. A pillar 3a deduction may improve the result, but it is not an immediate cash payment equal to the deducted amount. Keep an estimated tax balance visible throughout the year and revise it when income or residence changes.
Fund annual bills every month
Many budgets fail because of bills arriving once or twice a year, rather than daily small purchases. Make a list of predictable payments: insurance premiums, vehicle charges, broadcasting fee, memberships, holidays, gifts, dental work, servicing and taxes. Divide the expected annual total by twelve and transfer that amount each month into a separate provision account. For example, a household expects CHF 8,400 of tax, CHF 3,600 for holidays, CHF 1,200 for car maintenance and CHF 1,800 for other annual bills. That is CHF 15,000 a year, or CHF 1,250 per month. Without a provision, the household's monthly saving ability appears exactly that much too high. Once a year, compare the estimate with actual payments. If health premiums or rent change, adjust the standing order from the following month. Families often face uneven childcare and school-holiday costs; self-employed people also have variable income and contributions. Money in a provision is not wealth available for a new goal. It already belongs, in practical terms, to the future bills. Keep it distinct from an emergency reserve. A simple arrangement with a current account, a provision account and a reserve can be clearer than dozens of detailed savings pots. The important test is whether the cash is actually there when each bill falls due.
Size the emergency reserve around your risk
An emergency reserve is for surprises, not tax, holidays or a kitchen replacement already planned. The right size depends on fixed costs, the number of incomes, job security, health and dependants. A couple with two stable salaries and modest costs may plan differently from a one-earner family with a mortgage. First calculate how many months of essential spending could be covered without new income. Count housing, food, health insurance, childcare, transport and contractual obligations, rather than assuming the whole leisure budget must continue. For example, essential expenses are CHF 5,200 per month. An accessible reserve of CHF 20,800 covers four months arithmetically. Whether that is enough depends on the employment outlook and other support. If it helps your overview, separate a small immediately available repair fund from a larger buffer for income loss. Hold the reserve in a form you can use without selling volatile investments or meeting a statutory withdrawal condition. An equity portfolio or restricted pillar 3a assets can serve long-term goals but are not dependable substitutes for cash needed within weeks. After using the reserve, plan to rebuild it before increasing fixed savings commitments. Agree on the rule within the household so that everyone understands what the money is for.
Health insurance is an annual risk, not just a premium
The health insurance premium is a major fixed expense, but real healthcare costs also include the deductible, percentage co-payment and sometimes a hospital contribution. The Federal Office of Public Health states an ordinary adult deductible of CHF 300 and a subsequent ten percent co-payment capped at CHF 700 a year; higher optional deductibles change what you pay yourself. Compare at least one year with low treatment costs and another with high costs. A CHF 2,500 deductible can require substantial cash when someone becomes ill even if the monthly premium is lower. This risk belongs in the reserve calculation. Different rules apply to children, and pregnancy and maternity have particular provisions that may need checking for the actual situation. For example, a person saves CHF 900 a year in premiums by choosing a higher deductible but has almost no accessible savings. The small monthly advantage does not remove the risk of a sudden medical bill. Check whether the household may qualify for a cantonal premium reduction. Treat basic and supplementary health cover separately because contract terms and the consequences of changing providers differ. Update the healthcare line of the budget each year after new premiums are announced and after significant changes in the household.
Rank debts and contracts by the burden they create
A plan should show ongoing commitments even when they are scattered across cards and apps. For every loan, record the balance, interest rate, monthly instalment, end date and special terms. Include leasing, purchases on instalments, maintenance obligations and private loans. Distinguish contractual fixed payments from variable expenses that could be cut if needed. High interest on consumer debt is a known cost, whereas an expected investment return is uncertain. It may therefore be sensible to assess paying down expensive debt before adding long-term investments. Do not apply this mechanically: early repayment penalties or tax effects may call for a closer look. Imagine a household paying CHF 300 a month for a device, CHF 450 for a car and CHF 250 for an older loan. The payments appear in different parts of the bank statement but tie up CHF 1,000 every month together. Counting only rent and health insurance as fixed costs would overstate spare cash. Each time a contract ends, decide whether the released amount goes into reserves, debt reduction or a specific goal. Do not take on a new fixed payment merely because an old one disappears. Over time, this approach gives the household more flexibility to handle job changes and family needs.
Put goals in order by date and importance
A monthly surplus is not yet a plan. List larger goals with an amount and a date: further education in two years, a home deposit in five, extra retirement provision by 65, or financial help for parents abroad. Classify each as necessary, important or optional. A mandatory tax provision does not compete on the same footing as an optional car upgrade. Match each goal with a suitable source of funding. Money needed for a purchase in two years should not depend entirely on a favourable equity market. A distant retirement goal can have a different risk horizon if reserves and loss tolerance are adequate. For example, a couple saves CHF 1,400 a month: CHF 500 toward renovation in three years, CHF 400 toward pensions and CHF 500 toward a home deposit. After a child is born, childcare adds CHF 600 a month. The amounts and dates now need renegotiation; continuing all three unchanged would not fit the arithmetic. Write the choice down. A sound plan makes competing goals visible instead of hiding them behind one savings percentage. Ask whether inflation affects the goal as well. Something costing CHF 100,000 today may cost more in ten years. Use a transparent assumption, not a guaranteed prediction, when estimating the future target.
Consider saving and protection together
Saving for retirement is only one part of household planning. Ask what would happen if an earner became ill for a long time, had an accident or died. Needs vary: rent and child-related costs continue while an income may stop. Compare the annual minimum requirement with possible payments from AHV or IV, an occupational pension fund, accident cover and existing policies. Obtain the current pension statement and the actual contract terms for a reliable overview. The 13th AHV payment introduced in 2026 applies only to old-age pensions; disability and survivors' pensions are still paid twelve times a year. A household with CHF 110,000 in gross income should not assume that 80 percent is automatically insured. That percentage might express a desired income replacement, but it is not a promised statutory benefit. Model retirement, disability and death separately. A person who moved to Switzerland later also needs to review Swiss AHV contribution years and foreign pension rights. A large pillar 3a payment may have a tax benefit without solving an immediate protection need. Conversely, insurance may be unnecessary when existing assets and benefits already cover the exposure. The goal is to identify a measurable gap, not to build the longest possible list of products. Update the calculation after a birth, job change or property purchase.
Use scenarios to test whether the plan is robust
A budget that works only in the best year is too tight. Calculate at least three versions: normal development, a temporary loss of income and a large one-off expense. The baseline should use realistic pay and known bills. In the second version, working hours might fall for twelve months or a bonus might disappear. In the third, a renovation or medical issue could cost CHF 10,000. In each case ask whether rent, tax and health insurance remain payable, whether reserves are needed and which voluntary savings could temporarily pause. For example, two earners receive CHF 10,000 net per month and plan spending plus saving of CHF 9,700. If one income falls by CHF 2,000, the household has a CHF 1,700 monthly deficit. The positive baseline margin of CHF 300 says little about its ability to cope. A stronger plan identifies expenses that can be reduced and how many months the reserve can carry the remaining deficit. Higher mortgage interest or healthcare costs are also useful stress cases. Do not treat a fixed investment return as guaranteed money for current living costs. These scenarios are not meant to predict events precisely. They show which decision today remains affordable under several plausible outcomes.
Plan for a household connected to another country
If you live between Switzerland and another country, or regularly support family abroad, include additional budget lines. Record transfers, travel, a second home, insurance and foreign-exchange costs. First keep each amount in the currency actually paid, then state the exchange rate used in the combined overview. Sending EUR 500 a month to parents in Portugal represents a Swiss franc cost that can move. For long-term goals, use a cautious buffer instead of one seemingly exact fixed exchange rate. If a future move is planned, separate one-off relocation costs from the new annual cost of living. Estimate Swiss and foreign pensions separately; a year worked abroad is not automatically a Swiss AHV contribution year. Check whether you hold assets or property, or have tax obligations, in more than one country. The financial plan can make these questions visible but does not replace a cross-border tax assessment. For example, a family may be renting and paying childcare in Zurich while saving for a property in Portugal. The overseas goal should not consume the Swiss emergency reserve. Give it its own amount and date. That makes it possible to see whether both locations are financially sustainable at the same time.
A short monthly routine keeps the plan current
Twenty minutes at month-end can provide a useful check. Compare actual income and spending with the plan. Confirm that monthly provisions were transferred and the emergency reserve remains available. Note the cause of material differences without assigning blame. An expensive month because of school enrolment differs from a continuing increase in food costs. Each quarter, review open contracts and progress toward goals. Once a year, update tax, health premiums, pension statements, insurance and the reserve target. Track a few indicators: accessible reserve measured in months of essential spending, monthly surplus after provisions, remaining debts and progress toward important goals. For example, the plan shows an expected CHF 800 surplus for six months but account balances barely rise. Find the difference in card payments, cash or irregular bills before increasing a standing savings transfer. Automation helps, yet does not replace a reality check. If income changes with a new job, part-time work or self-employment, do more than change the monthly income cell. Update tax, social contributions, the pension fund and protection against disability or death as well. A plan is a working document, not a one-time spreadsheet.
Checklist for a sustainable financial plan
Collect twelve months of account statements, current payslips, the latest tax assessment, health and other insurance contracts, and the occupational pension statement. List income, monthly fixed costs and bills arriving only during the year. Transfer the monthly share of known annual bills to a provision account. Calculate the genuinely available surplus and see whether changes in assets confirm it. Set an immediately accessible emergency reserve based on essential expenses. Record loans with interest rates and terms. List goals with amount, priority and target date. Compare needs with existing benefits for retirement, disability and death. Test the plan against income loss and an unexpected bill. Only then decide how much belongs in pillar 3a, the pension fund or accessible investments. Ask which figure is a contractually promised benefit, which is an official estimate and which is merely a modelling assumption. A plan is useful when another person can understand its main figures and decisions. It does not need to predict every purchase to the last franc. Set a review date, especially after a major change in work or family life. This turns a budget list into a tool for choices.
Organise shared finances fairly
Partners often keep separate accounts while many financial decisions affect them both. Agree which expenses are shared, how much each contributes and who monitors annual bills. Splitting everything equally can be difficult when income differs greatly; an agreed division based on available means may be more sustainable. Include unpaid care work and the effect of reduced hours on the future pension. For example, one partner takes home CHF 7,000, the other CHF 3,000 and does much of the childcare. Dividing every joint bill in half could leave the second person without a personal reserve. Record individual savings and pension entitlements as well as the joint position. A shared account may simplify regular bills, but it does not replace discussion of goals, debts and support for relatives abroad. In the event of separation or death, it should be clear which contracts exist and where records can be found. Check whether the lower earner continues to build AHV contribution years and occupational pension benefits. The issue is not only whether the household as a whole saves enough, but who will own future income and assets. Hold an annual meeting to review the figures and priorities. Agree on a spending threshold for discussing major purchases and keep important documents locatable without sharing private passwords.
