🧾 Take-Home Pay Estimator

Enter your gross salary and the percentages taken by tax and other deductions. The calculator shows monthly take-home pay. Because tax systems vary by country and personal situation, this is a transparent estimator you control — not a black box claiming false precision.

Marginal vs effective tax rate — the classic confusion

Your marginal rate is the tax on your next dollar; your effective rate is total tax divided by total income, and it is always lower in a progressive system because early slices of income are taxed lightly or not at all. "I'm in the 24% bracket" does not mean 24% of your salary disappears — a single US filer at $70,000 pays an effective federal rate closer to 13–15%. Use the effective rate here.

Finding your real numbers

  • Last year's tax return is the gold standard: total tax ÷ total income = effective rate.
  • A recent payslip works too: identify each deduction line and convert it to a percentage of gross.
  • Moving or changing jobs? Look up the destination country's or state's typical burden for your income level, then refine after the first payslip.

What to do with the result

Budgets built on gross pay fail immediately. Anchor your rent, loan and savings decisions to the net figure. A common allocation for the net amount is 50% needs / 30% wants / 20% savings and debt — see our 50/30/20 budget calculator to split it automatically.

Frequently asked questions

Why not calculate the exact tax for my country?

Exact tax depends on filing status, dependents, deductions, credits and local rules that change yearly. Tools that promise exactness for every reader quietly go stale. This estimator makes the assumptions visible and editable, which is more honest and more portable.

What effective rate should I guess if I have no history?

Very roughly: US single filers at average incomes often land at 12–20% federal-plus-state; much of Western Europe lands at 25–40% including social charges. Adjust after your first real payslip.

Are bonuses taxed differently?

They are often withheld at a higher flat rate during the year, but at filing time they are ordinary income in most systems — the effective-rate approach here handles them fine over a full year.
