Loan Calculator (Switzerland)
Calculate monthly instalments & total interest for a Swiss personal loan. Test scenarios to find a monthly payment that stays affordable—even in “bad months”.
- Monthly instalment – see what you’d pay per month for a given amount, term, and interest rate.
- Total cost – understand total interest and total repayment (not just monthly).
- Stress test – compare multiple terms to choose a safer monthly payment.
This loan calculator helps you estimate your monthly instalment and total interest based on loan amount, term, and an annual interest rate. It’s a planning tool—not an offer.
Tip: If your monthly payment only works in “perfect months”, the loan is too risky. Learn the full framework in Personal Loan Switzerland – Guide.

3. The key trade-off: lower monthly vs higher total cost
Longer terms usually reduce your monthly payment but increase total interest. This is why “the cheapest monthly option” can be the most expensive overall.
- Pick the shortest term that still feels safe month-to-month.
- Keep a buffer so you never need credit cards to survive.
- If the monthly payment is too high, check alternatives before borrowing more.

4. Stress test your budget before borrowing
Before taking a loan, test your budget with the calculated monthly instalment for at least 1–2 months. If you can’t maintain it, don’t lock it in for years.
FAQ: Loan calculator Switzerland
Is this loan calculator accurate for Swiss lenders?
It gives an estimate using equal monthly payments (annuity) with a fixed APR. Real offers can vary by provider, fees, and your creditworthiness. Use it to compare scenarios and affordability—not as a final quote.
What interest rate should I enter?
Use a realistic estimate based on your situation, then run multiple scenarios (e.g., low / medium / high APR) to see how much the monthly payment changes.
Should I pick the longest term to get the lowest monthly payment?
Not automatically. Longer terms often mean more total interest. The best choice is usually the shortest term that still keeps your monthly budget stable.
Where should I go next?
Read “Personal Loan Switzerland – Guide” for requirements and risks, and “Loan Providers Comparison” if you want a structured way to compare offers.
