Every calculator on the site, all free, none requiring a signup, and all of them reading the same figures the guides do — so a number here can never disagree with a number on the page that explains it.
Pay and Tax
The two things every pay calculator here gets right and most get wrong
Order of operations. Unemployment insurance and the second pillar pension come out before income tax is calculated, not after — treating them as post-tax deductions overstates tax on every salary. And the employer's side. Social tax at 33% is paid by the employer on top of your gross, not deducted from it, so your gross is not what you cost. Both are shown.
Money
If a calculator quotes you a capital gains rate for Estonia, it is describing another country
Estonia has no separate capital gains tax for a resident individual. Investment gains are income, taxed at 22%. Our own investment code carried a hard-coded 15% until August 2026 — a rate belonging to a neighbouring country's system rather than Estonia's. It never reached a live page, and it is fixed. We mention it because a reader has no way to audit a calculator's constants and is entitled to know when we have found one of ours wrong.
How we build them
Four rules, and they are the reason to trust the output rather than a reason to trust us.
Every constant comes from one file. No calculator holds a rate of its own. They all read config/figures.ts, where each figure carries its source and the date it was read — so the 22% in a calculator and the 22% in a guide are the same variable, and cannot drift apart.
Dates are inputs, not assumptions. The minimum wage rose on 1 April 2026, so there is no single correct 2026 minimum wage. The hourly calculator takes a date and applies the rate that was in force, rather than hard-coding one figure and being wrong for a quarter of the year.
The arithmetic is tested, and the tests are derived rather than copied. A test fixture copied from wherever a number came from will agree with itself forever, however wrong the number is — which is exactly how a foreign tax rate survived in the investment code. Expectations are now derived from the constants, and the constants are asserted separately.
What is not modelled is stated. Overtime premiums, sequence-of-returns risk, currency risk, your specific contract. Each calculator says what it leaves out, because a projection that hides its assumptions is worse than no projection.
