Mortgage affordability calculator 2026
How large a mortgage a bank approves is set by two limits, and the smaller one decides: servicing capacity and the loan cap (lainakatto). For servicing capacity, all your loan-servicing costs must not exceed 60% of net income when stress-tested at a 6% rate over a 25-year term. For example, on a 3,000 € net income with no other loans, the servicing room is 1,800 €/mo, corresponding to about a 279,372 € loan.
The loan cap limits the mortgage to at most 95% of the collateral value, so at least 5% own funds is needed. With 40,000 € own funds, the maximum home price in the same example is about 319,372 €. The calculator shows both limits and tells you which one caps your loan. The result is indicative — the bank always makes an overall assessment.

The calculator is indicative and is not a loan offer or promise. It is based on general Finanssivalvonta recommendations (60% expense cap, 6% / 25-year stress test, 95% loan cap). The bank’s actual decision is based on an overall assessment and may differ. Always check your borrowing options with the bank.
How is the maximum loan calculated?
A bank estimates the maximum loan through two limits, and the smaller one decides. The first is servicing capacity: all loan-servicing costs at most 60% of net income, stress-tested at a 6% rate over a 25-year term (a Finanssivalvonta recommendation; the expense cap is in force from 1.1.2026). The second is the loan cap: the loan may be at most 95% of the collateral value, so at least 5% own funds is needed (loan cap from 30.6.2026). For example, on a 3,000 € net income with no other loans, the servicing room is 1,800 €/mo, which corresponds to about a 279,372 € loan; with 40,000 € own funds the maximum price is about 319,372 €.
What limits the size of a mortgage?
Servicing capacity is usually the decisive limit. Per the Finanssivalvonta recommendation, all loan-servicing costs must stay below 60% of net income when calculated at a 6% stress rate over a 25-year term. The expense cap was tightened to 60% from 1.1.2026. Other loans — consumer loans, car loans, student loans and housing-company loans — reduce the servicing room left for the mortgage.
The loan cap (enimmäisluototussuhde) limits the mortgage to at most 95% of the collateral value. Finanssivalvonta raised the cap to 95% for all borrowers on 30.6.2026. In practice a bank may still require more own funds or extra collateral, because a home’s collateral value is typically below its purchase price.
The stress test is done at a 6% rate, even if the current rate is lower. This ensures you can manage the loan if rates rise. The test directly limits the loan amount: the higher the stress rate, the smaller the loan for the same servicing room.
You can reach a larger loan by increasing own funds, paying off other loans, applying together with a second applicant, or offering extra collateral or a guarantor. Stable, regular income and a low loan margin improve servicing capacity. The calculator is indicative and does not replace the bank’s decision.
Frequently asked questions
How large a mortgage can I get on my income?
As a rule of thumb, the payments on all your loans should be at most 60% of your net income when calculated at a 6% rate over 25 years. For example, on a 3,000 € net income with no other loans the servicing room is about 1,800 €/mo, corresponding to roughly a 279,000 € loan. You also need at least 5% own funds. The final amount is decided by the bank in an overall assessment.
What is the stress test and why 6%?
In the stress test the bank checks whether you can manage the loan if the rate rises. Finanssivalvonta recommends testing at a 6% rate over 25 years, even if the current rate is lower. This ensures the loan won’t become too heavy if rates rise. The test directly limits the loan amount approved.
How much down payment do I need?
At least 5% of the purchase price, because the mortgage can be at most 95% of the collateral value (the loan cap). In practice a bank may require more own funds or extra collateral, because a home’s collateral value is typically below its market price. A larger down payment also reduces the loan and interest costs.
Do other loans affect the mortgage?
Yes. All loan-servicing costs count toward servicing capacity — consumer loans, car loans, student loans and housing-company loans. The more other loans, the less servicing room remains for the mortgage. Paying off other loans before applying can increase the amount approved.
Is the calculator result the same as the bank’s decision?
No. The calculator gives an indicative estimate based on Finanssivalvonta recommendations. The bank always makes an individual overall assessment covering employment type, credit history, estimated living costs, family situation and collateral. The bank may also apply its own, stricter limits.
How can I get a larger mortgage?
Increase your own funds, pay down or clear other loans, or apply together with a second applicant. Extra collateral or a guarantor can also raise the amount. Stable, regular income improves servicing capacity. Compare banks too: a lower margin leaves more servicing room.
