CSN Loan

CSN annuity loans (for studies started after 2001) have a fixed repayment term. The monthly amount is calculated as an annuity: equal payments every month for the entire term.

Early on, a larger share of each payment goes to interest and a smaller share to principal. Towards the end, the ratio reverses. The interest rate is set annually by the government and has historically ranged from 0.3% to 2.1%.

Repayment normally begins six months after your studies end and runs for a maximum of 25 years.

The CSN rate is government-subsidised and based on the state borrowing cost (statslåneräntan), not on market rates like bank loans or mortgages. It is set annually by the government.

For 2026, the rate is 2.1%. Historically it has ranged from near zero (0.05% in 2021) to over 3%. Even in high-rate environments, the CSN rate is lower than what you can expect from equity market returns over time.

When you overpay your CSN loan, you save interest on the remaining balance. At 2.135%, each extra krona saves just over 2 öre per year in interest cost.

If you instead invest the same amount in an ISK with an expected return of 7%, each krona yields roughly 5.9% net after ISK schablonbeskattning (approx. 1.07% annual tax drag). The gap between 5.9% return and 2.1% interest saving means investing almost always wins over time.

Important: this assumes you actually invest the money. If the extra goes to spending instead of an ISK, overpaying is the better choice. There is also a psychological value in being debt-free that numbers do not capture.

You remain liable regardless of where you live. CSN can demand payment based on your global income. The annual amount is calculated on the income you report to CSN.

If you fail to pay, CSN can refer the debt to Kronofogden, resulting in a negative credit record even when living abroad. Always notify CSN of address changes and report your income. You can apply for a reduced amount if your income is low.

The write-off age depends on when you took the loan. Annuity loans taken 2001-2021 are written off the year you turn 68. Loans taken from 2022 must be repaid by the year you turn 64, and any remainder is written off the year you turn 71. No application is needed and the written-off amount is not taxed.

This means that if your repayment period extends beyond that age, you never repay the full loan. For most people this is irrelevant since the loan is normally repaid well before then, but it is reassuring to know.

You can pay extra on your CSN loan at any time with no penalty or fee. Extra payments go directly to principal (after any accrued interest is paid).

CSN offers two ways to pay extra: a one-off payment via their website, or permanently increasing your monthly payment. You can also lower it again if your finances change.

Note that extra payments shorten the loan term but do not change the regular monthly amount. You pay the same sum each month, but for fewer months.
