Intro
Borrowing can make sense when it serves a clear purpose, costs are understood and repayments leave room for essential spending, savings and setbacks.
A mortgage can help you buy a home. A loan can pay for training or replace a car you need for work. But a collection of small instalments can also leave you committed to spending next month’s salary before it arrives.
Debt means using money now that you must repay later, usually with interest. Managing it wisely starts with understanding that claim on your future income.
The aim is to make deliberate borrowing decisions, keep repayments manageable and reduce expensive balances. Being debt-free can be valuable, but having debt does not automatically mean your finances are unhealthy.
When can borrowing make sense?
Borrowing may be reasonable when it supports a worthwhile goal and you can repay it without relying on optimistic assumptions. The purpose matters, but so do the price and repayment terms.
The familiar distinction between “good debt” and “bad debt” can oversimplify things. A home loan can become unaffordable. Education does not guarantee higher earnings. Even a necessary purchase can be financed on poor terms.
| Purpose | Why borrowing may make sense | What to examine |
|---|---|---|
| Buying a home | Spreads a large purchase over time | Interest-rate risk, maintenance costs and the consequences of missed payments |
| Education or training | May improve skills and earning opportunities | Course quality, realistic employment prospects and repayment obligations |
| An essential vehicle | May support work or family needs | Cheaper alternatives, running costs and how long the vehicle will remain useful |
| A discretionary purchase | May bring spending forward | Whether waiting and saving would avoid an unnecessary ongoing commitment |
A useful question is: will this purchase still be helping me while I am paying for it? A short holiday paid off over several years deserves particular scrutiny.
Borrowing to invest requires additional caution. Investments can fall in value while the loan remains payable. A lender may also require more collateral or sell pledged investments, depending on the agreement. An expected investment return is not a dependable repayment plan.
How do you know whether debt is affordable?
Affordable debt fits within your actual household budget and leaves a margin for change. A lender’s approval does not tell you how comfortable the commitment will feel alongside your other goals.
Start with reliable take-home income. Subtract essential spending, existing repayments and an allowance for irregular expenses such as insurance, maintenance or annual bills. Then consider the savings you need to maintain.
Suppose your household receives CHF 6’000 a month, essential spending is CHF 3’800 and existing debt repayments are CHF 700. That leaves CHF 1’500 before additional savings, irregular expenses and discretionary spending. A new CHF 500 repayment would use one-third of that remaining amount.
These are hypothetical budget figures, not affordability thresholds. The same payment can be manageable for one household and risky for another.
Test the budget against a temporary income reduction, a large repair bill and higher payments if the interest rate can change. If repayment depends on a bonus, a pay rise or selling an asset at a favourable price, the plan needs more breathing room.
How much does borrowing really cost?
The monthly payment shows the immediate commitment. The total amount repayable shows the longer-term cost.
Before signing, check the interest rate, fees, number of payments and whether the rate is fixed or variable. Look for introductory rates, a large final payment and charges for early repayment. Where an annual percentage rate or equivalent effective-rate measure is provided, check which costs it includes.
A hypothetical CHF 10’000 loan repaid through 36 monthly payments of CHF 320 costs CHF 11’520 in total. The same amount repaid through 60 payments of CHF 210 costs CHF 12’600. The second payment is smaller, but the total financing cost is CHF 1’080 higher.
These examples assume equal monthly payments, no separate fees and no final balloon payment. They illustrate payment schedules, not current loan offers.
An interest-free offer also deserves attention. Check whether fees apply, whether the cash price is lower and what happens after a missed payment or the promotional period ends. Several instalment plans can create a significant combined obligation even when each looks small.
Which debts should you repay first?
First distinguish urgent overdue obligations from debts you can service normally. If you are behind on payments, the consequences of non-payment may matter more than the interest rate. Housing, essential services and legal obligations need particular attention. Exact priorities and remedies depend on your country and circumstances. Seek local debt advice if you cannot cover essential bills and required repayments.
Once urgent obligations are addressed, use your household budget to work out how much you can realistically repay each month. Preserve some accessible emergency savings so an unexpected expense does not immediately force you to borrow again.
With required payments covered, you can choose between two repayment strategies we explore in our guide to managing money: the debt avalanche and debt snowball methods.
What is the debt avalanche method?
The debt avalanche method prioritises your most expensive borrowing. Pay the required amount on every debt, then direct any extra money towards the balance with the highest interest rate. Once it is cleared, move to the next-highest rate.
For example, with hypothetical balances charging 15%, 8% and 3%, the 15% balance receives the extra payment first. With comparable terms, unchanged rates and no early repayment charges, this approach generally minimises total interest costs.
What is the debt snowball method?
The debt snowball method prioritises your smallest balance. Keep making the required payments on every debt, but direct extra money towards the smallest one until it is cleared. Then redirect the freed-up payment towards the next-smallest balance.
Closing an account can provide a quick, visible result and help you maintain momentum. However, you may pay more interest overall because the smallest balance is not necessarily the debt with the highest rate.
The avalanche focuses on reducing interest costs; the snowball focuses on building motivation through early wins. Choose an approach you can sustain and check repayment restrictions or charges before paying extra.
Should you build savings or repay debt?
Some accessible savings can prevent the next unexpected bill from becoming another loan. At the same time, holding substantial cash while paying expensive interest can be costly.
A practical approach is to maintain a modest cash buffer, meet required payments and focus additional money on costly debt. As those balances fall, you can build a larger reserve suited to your essential spending, income stability and responsibilities.
There is no single amount that suits everyone. A household with uncertain income may need more accessible cash than one with predictable earnings.
Repaying debt reduces future interest charges, subject to the loan terms and any repayment fees. Investing offers uncertain returns. Comparing an expensive borrowing rate with an optimistic stock-market forecast overlooks that difference. Pension incentives, tax treatment and withdrawal restrictions may also affect the decision and should be assessed locally.
Can consolidating debt help?
Debt consolidation combines several balances into a new borrowing arrangement. It can simplify administration and may reduce costs if the new terms are genuinely better.
Compare the total remaining cost of your existing debts with the new loan, including fees. A lower monthly payment may simply reflect a longer repayment period. The US Consumer Financial Protection Bureau warns that this can increase the total amount paid.
Also check whether unsecured borrowing would become secured against your home or another asset. That changes what is at risk if you cannot repay. Consolidation needs to accompany a workable budget: clearing existing balances with a new loan while borrowing again can leave you owing more.
Can interest-free debt still stretch your budget?
Imagine two households, each with CHF 6’000 in monthly take-home income and CHF 4’500 in spending before debt repayments. Both have CHF 1’500 left to cover repayments, savings and unexpected costs.
The first household pays CHF 350 a month on a fixed-rate loan used to replace a car needed for work. The second has no interest-bearing loans, but pays CHF 900 a month across several interest-free instalment plans for furniture, electronics and holidays.
| Monthly budget | Household A | Household B |
| Take-home income | CHF 6’000 | CHF 6’000 |
| Spending before debt repayments | CHF 4’500 | CHF 4’500 |
| Debt repayments | CHF 350 | CHF 900 |
| Remaining for savings and unexpected costs | CHF 1’150 | CHF 600 |
Household B pays no interest, yet has much less room to handle a setback. If both households’ monthly income temporarily falls by CHF 800, Household A still has CHF 350 left after spending and repayments. Household B faces a CHF 200 shortfall.
This does not prove that the car loan is a better deal overall. Its interest charges, outstanding balance and repayment period still matter. But it reveals something that an interest rate alone cannot: even free borrowing can become unaffordable when too much future income is already committed.
Before adding another repayment, total all your existing commitments and test what would happen if your income fell. The important number is how much flexibility remains once every payment has been made.
Hypothetical example. Spending and repayments are assumed to remain unchanged during the income reduction. Loan fees and total lifetime borrowing costs are not modelled.
What should you do if repayments become difficult?
Review your budget and contact the lender as soon as you see a problem. Explain what you can realistically afford and ask what arrangements may be available. Obtain any revised terms in writing and check their effect on interest, fees and repayment time.
Persistent borrowing for groceries or bills, using new credit to meet old repayments and growing balances despite regular payments are reasons to seek qualified, independent debt advice in your country.
Debt difficulties can follow illness, separation or lost income. Getting support early gives you a clearer view of your options.
Identify what the loan will achieve and whether a cheaper alternative could meet the same need.
Check the total repayment, fees, rate changes and any collateral at risk.
Use realistic income assumptions and leave space for essential spending and unexpected costs.
Managing debt wisely starts with understanding what you owe, what it costs and how repayments fit your budget. Prioritise urgent obligations, reduce expensive balances and preserve some accessible savings for unexpected expenses.
Borrowing can make sense when it serves a clear purpose and you can repay it without depending on a pay rise or investment gains. The goal is to keep today’s commitments from limiting tomorrow’s choices.
Frequently asked questions
Is it always better to be debt-free?
Being debt-free removes repayment commitments. However, affordable borrowing can support a useful goal. Consider its cost alongside your need for accessible savings and other priorities.
Is a mortgage automatically good debt?
No. It finances a potentially useful asset, but property values can fall and ownership brings additional costs. Affordability and loan terms still matter.
Should I pay off the smallest debt first?
That may help motivation. Paying the highest-rate debt first generally saves more interest under comparable terms. Address urgent arrears before choosing either strategy.
Does an interest-free instalment plan count as debt?
Yes. It commits future income even when no interest is charged. Include every instalment in your budget and check fees and conditions.
Can inflation make debt easier to repay?
Inflation can reduce the real value of a fixed nominal balance. But repayments become easier only if your income keeps pace and other costs do not absorb the gain. Variable interest rates may also rise.
