Rent vs Buy Calculator for Norway 2026

The calculator compares renting with buying in Norway by looking at what you are worth after a number of years. Both alternatives start with the same money and the same monthly budget. The buyer uses their equity to buy and pays stamp duty and registration fees, then pays interest, principal, common costs and maintenance. The renter pays a deposit, invests the rest of the starting capital in funds, pays the rent, and invests the difference whenever renting is cheaper per month than owning. Whoever has the lower housing cost in a given month invests the difference, so the comparison is fair.

How the calculator works

• Buying: an annuity mortgage on the price minus your equity. Each month you pay interest and principal, common costs and municipal charges, and maintenance (1% of the home value a year by default). The interest gives a tax deduction of 22%. Wealth is the home value after selling costs minus the remaining debt.
• Buying costs: stamp duty (dokumentavgift) of 2.5% of the value for a freehold home, none for a housing co-op share, plus a registration fee (tinglysingsgebyr) of NOK 545 per document, one for the deed and one for the mortgage.
• Renting: the rent rises every year in line with inflation. The deposit (at most 6 months' rent under the Tenancy Act) stays in a deposit account and is returned. The rest of the capital is invested in funds, and gains are taxed at 37.84% when sold.
• Break-evenis the first year in which the buyer's wealth is at least as large as the renter's.

Norwegian housing terms you will meet

The lending regulation was continued without an end date in December 2024, when the limit was raised to 90%. The borrowing calculator and the mortgage stress test apply the rules to your own figures.

Worked example: a NOK 4,500,000 flat with NOK 900,000 equity

You can buy a freehold flat for NOK 4,500,000 with NOK 900,000 of your own money, or rent a similar one for NOK 18,000 a month. The loan is NOK 3,600,000 at 5% over 30 years, which is NOK 19,326 a month. Stamp duty of NOK 112,500 and registration fees bring the buying costs to NOK 113,590. With NOK 3,500 a month in common costs and municipal charges, 1% a year for maintenance and the interest deduction, the buyer pays about NOK 23,298 a month in year one, against NOK 18,000 for the renter. The renter puts NOK 54,000 in a deposit account (3 months' rent), invests the remaining NOK 959,590 in funds at 6% a year, and invests the monthly difference of NOK 5,298 (the renter pays less each month).

House prices grow 4.3% a year in the example, the average for all of Norway in the last ten years (2015 to 2025: 4.31%, from Statistics Norway's used-home price index). Rent rises 3.3% a year, the average consumer price inflation over the same period (3.25%).

In the first year the renter is ahead, because buying costs and selling costs eat up the price rise. From year 2 the buyer is ahead, and after 10 years the difference is +NOK 1,702,862. The reason is leverage: the buyer gets the price rise on the whole home but put in only NOK 900,000. The mortgage principal you repay is not a cost. It is forced saving, which is why the calculator counts it in your wealth. Interest over the 10 years is NOK 1,647,384, of which NOK 362,424 comes back as an interest deduction.

What if house prices rise more slowly?

Price growth matters most. The table shows the same example over 30 years with different yearly price growth. A positive difference means that buying leaves you with more wealth.

With no price growth, buying comes out ahead in year 23. If you stay only three years, buying leaves you with NOK 335,234 less wealth than renting. What your savings earn also matters: with 2% price growth and an 8% return instead of 6%, buying comes out ahead in year 7, against year 5 with a 6% return.

Interest, the interest deduction and repayments

Interest on debt is deducted from your ordinary income, which is taxed at 22%, so the government pays 22%of your interest in lower tax. A higher interest rate raises the owner's costs immediately, while a renter only feels it if the landlord raises the rent. Try a rate 2 percentage points higher to see how robust buying is (the mortgage stress test does the same for the payment). In a housing co-op you avoid stamp duty (on the example flat, NOK 112,500), but the shared debt is part of what you take on and your monthly charges include interest on it. Treating the same flat as a co-op share, with the same price and the same monthly costs but no stamp duty, would change the 10-year result to +NOK 1,870,666.

When renting wins

Renting tends to win when you expect to move within a few years, when the rent is low compared with the price, or when you expect weak price growth. It also gives flexibility and no risk of large repair bills. But it only wins financially if you actually invest what you save. If you spend it, the renter's wealth ends up far below what the calculator shows. Check the deposit rules and the rent rules before you sign: see the rent deposit calculator and the rent increase calculator.

If you have just moved to Norway

• Check the total price of a co-op flat.The debt you take over through the common charges is part of the cost of the home, and it counts in the bank's loan-to-value calculation.
• Bids are binding. Line up your financing before the viewing. The bank will confirm how much you can borrow, and the agent will ask for proof.
• Save the deposit and the fees. With a 10% equity requirement and about 2.5% of the price in stamp duty on a freehold home, you need cash for both. See the cost of buying a home and the stamp duty calculator. A BSU savings account can help you build equity if you qualify: see the BSU calculator.
• Ask a bank early. Whether a bank lends to you depends on your income, your other debt and the rules above. This calculator does not assess that.
• Property tax. Some municipalities charge a yearly property tax (eiendomsskatt). See the property tax calculator, and use the mortgage calculator for the payment.

What this calculator does not cover

It leaves out wealth tax, the tax-free allowance on fund gains (skjermingsfradrag), interest on the deposit account, property tax and renting out part of the home. It assumes one interest rate for the whole period, a fixed rate of price growth and return every year, and that the interest deduction arrives every month. Real markets go up and down, so treat the result as a comparison of assumptions, not a forecast. It does not include transfer fees some co-ops charge, moving costs (use the one-off costs field) or the value of living where you want. It is not financial advice, and it cannot tell you whether a bank would lend to you.
