- Straight amortization: the same amortization every month plus interest on the remaining balance, so the payment falls over time. A percentage is per year of the total loan. With several loan parts, the amortization is shared between them in proportion to their size.
- Each part's rate stays the same for the whole calculation, whether fixed or floating — in reality floating rates change and fixed rates are renegotiated when the fixed period ends. Monthly interest is the balance × annual rate ÷ 12.
- Moving bank and negotiating a discount keep the same loan parts and amortization — only the rates change. A switching cost is paid once, up front, and is not added to the loan.
- Your rate is the bank's list rate minus your discount, in percentage points.
- Totals run until the loan is paid off, or for at most 50 years if the amortization is low or zero.
- Swedish loan-to-value limits and amortization requirements are not applied.
- Fees, taxes, insurance and interest deductions are not included.
- Amounts are in Swedish kronor (SEK), rounded to the nearest öre.
How it works
How the mortgage cost is calculated
A mortgage costs interest and amortization. The calculator works month by month until the loan is paid off, or for at most 50 years.
Straight amortization
Swedish mortgages are usually amortized straight: you repay the same amount every month, and interest is charged on what’s left of the loan (the annual rate divided by twelve). So the first month is the most expensive, and the cost falls as the debt shrinks.
You enter the amortization in kronor per month or as a percentage of the loan per year. The amortization requirement is 2 % a year while the loan is more than 70 % of the home’s value and 1 % while it’s more than 50 %, but the calculator uses what you enter.
Loan parts
Many split their mortgage into parts with different rates – say one floating and one fixed. The calculator works out each part separately, shares the amortization between them by size and shows an average rate for the whole loan.
Moving bank or negotiating the rate
- Move bank: the same loan and amortization at a new rate. Enter what the move costs, such as an interest differential fee for leaving a fixed rate early, and see after how many months it pays for itself.
- Negotiate the discount: your rate is the bank’s list rate minus a discount. The calculator shows what a bigger discount saves per month and in total.
The cost is shown before the interest deduction. Work that out with the tax refund calculator, or read how it works in the guide Interest deduction in Sweden.

Questions
Frequently asked questions
What's the difference between straight amortization and an annuity?
With straight amortization, which most Swedish mortgages use, you repay the same amount every month and pay interest on what's left of the loan – so the monthly cost falls over time. With an annuity, the monthly payment stays the same while the share going to repayment grows.
How much do I have to amortize?
Under the Swedish amortization requirement, 2 % of the loan a year while it is more than 70 % of the home's value, and 1 % a year while it is more than 50 %. The calculator uses the amortization you enter.
Is it worth moving my mortgage to another bank?
It depends on the rates and on what moving costs. With a fixed rate, the bank may charge an interest differential fee (ränteskillnadsersättning) if you leave before the fixed period ends. The calculator shows how much interest you save and after how many months the move pays for itself.
What are the list rate and the discount?
The list rate is the bank's published rate for each fixed period. Your own rate is usually the list rate minus a personal discount in percentage points, which you can negotiate. The calculator works out what a bigger discount is worth.
Is the interest deduction included?
No, the calculator shows the cost before the interest deduction. To see how much tax you get back on the interest, use the tax refund calculator.
