Calculations use the 2026 national-average kommunalskatt (32.38%, per Statistics Sweden) and the 2026 statlig inkomstskatt brytpunkt (660,400 SEK/year, per Skatteverket) at a flat 20% above that threshold. Includes the 2026 grundavdrag (basic allowance), jobbskatteavdrag (earned income tax credit), skattereduktion för förvärvsinkomst and public service fee, per Skatteverket's 2026 technical description (SKV 433). Leaves out allmän pensionsavgift (the 7% employee pension fee, fully offset by a matching tax credit), the burial fee (about 0.3%) and the optional church fee, and uses the national-average rate rather than your municipality's (28.93%–35.65% range).

≈ 1 571 900 kr gross a year
At a median 7 145 kr/day, contract work grosses about 1 571 900 kr a year over 220 billable days, 116% more than the 729 000 kr permanent median. That premium has to pay for what an employer would otherwise cover: paid holiday and sick days, pension contributions, and the gaps between contracts.
Contract and permanent benchmarks come from separate samples, so treat the gap as a guide rather than a like-for-like quote. See Quantitative Developer (C++ / Python) contract rates and contractor take-home →
