Mortgage calculator
Calculate the monthly cost of a Swedish mortgage in 2026 under the new rules: 90% ceiling, 1–2% amortisation and 30/21% interest tax relief.
New Swedish mortgage rules from 1 April 2026
On 1 April 2026 the Act (2026:226) on limiting residential credits entered into force and replaced the earlier regulations from Finansinspektionen. The mortgage ceiling was raised from 85 to 90 percent of the property value, meaning the down payment is at least 10 percent when buying a home. For increasing an existing mortgage a limit of 80 percent applies instead.
The amortisation requirement is based on the loan-to-value ratio: if the loan exceeds 70 percent of the property value at least 2 percent of the loan must be amortised per year, between 50 and 70 percent at least 1 percent applies, and below 50 percent there is no statutory requirement. The stricter requirement of an additional 1 percent for households with loans above 4.5 times gross income has been abolished.
Interest is deductible: you receive a tax reduction of 30 percent of interest expenses up to 100,000 kronor per year and 21 percent on the part above that. The calculator includes this, so the monthly cost is shown both before and after the deduction.
The bank always makes its own affordability calculation (KALP) using a stress-tested rate well above your actual rate, and may require more amortisation than the law. Running costs, condominium fees and payments on any personal loans are not included above.
