Frequently Asked Questions
What kalkylränta do Swedish banks use in 2026?
Most major Swedish banks (SEB, Handelsbanken, Nordea, Swedbank) use a kalkylränta of 7% for KALP stress tests in 2026. This is an industry standard, not a regulatory fixed rate. With the Riksbanken policy rate at 1.75%, the 7% stress rate is roughly four times the current level.
What is the 10% down payment rule in Sweden?
The Swedish mortgage cap (bolånetak) under Lag 2026:226 limits mortgage lending to 90% of the property value. You must provide at least 10% of the purchase price in cash (kontantinsats). On a SEK 4,000,000 property that is SEK 400,000 minimum.
How does the ränteavdrag reduce my monthly cost?
Sweden gives a 30% tax reduction on mortgage interest up to SEK 100,000 per year (per person), and 21% on interest above that. Skatteverket calculates this automatically. On SEK 80,000 in annual interest you get SEK 24,000 back — cutting your net monthly interest cost by 30%.
What is the 4.5× income multiple rule?
Swedish banks cap total mortgage lending at 4.5 times your gross annual household income. On a combined income of SEK 1,200,000/year the ceiling is SEK 5,400,000. This is separate from the bolånetak and KALP — you must pass all three tests.
How much amortisation am I required to pay?
Under FFFS 2016:16 (amended FFFS 2022:12): LTV above 70% requires 2%/year; LTV 50–70% requires 1%/year; below 50% no mandatory amortisation. The extra 1% for loans above 4.5× income was removed in February 2023.
