Interest Rate vs Monthly Cost
Frequently asked questions
How much does a 4 million SEK apartment cost per month?
A reasonable rough estimate is around 18,000–22,000 SEK per month after the Swedish interest tax deduction, assuming a 15% down payment, a 3–4% mortgage rate, mandatory amortization, and a typical BRF fee of 4,000–5,000 SEK. Use the sliders above to see your exact number — the BRF fee and your interest rate are the two inputs that move the result the most.
What is amortization?
Amortization is the part of your monthly payment that pays down the loan itself, separate from interest. Swedish rules (amorteringskravet from Finansinspektionen) require at least 1% per year of the loan if your loan-to-value is between 50% and 70%, and 2% per year if it is above 70%. Below 50% LTV there is no statutory requirement, though many banks still ask for some amortization.
How does the Swedish mortgage tax deduction work?
Sweden allows you to deduct mortgage interest in your tax return (ränteavdrag). You get back 30% of the interest you pay each year, up to 100,000 SEK of total interest expense per person — above that, the deduction drops to 21%. The deduction is calculated yearly but effectively lowers your real monthly cost; this calculator already shows the net figure after the deduction.
