About this tax calculator
The tax calculator estimates the tax you owe and your take-home income from your own inputs. You bring the rate — the tool does not bundle any country's tax brackets, so it never goes stale when tax tables change between years.
The formula is: taxable income = max(0, gross − deductions); tax = taxable × rate; net = gross − tax. The effective rate shown is tax ÷ gross × 100, which is what you actually paid as a share of your full income.
Worked example: with gross income of 75,000, deductions of 12,500, a 22% rate, and tax year 2025, taxable income is 62,500. Tax owed is 62,500 × 0.22 = 13,750, net income is 75,000 − 13,750 = 61,250, and the effective rate is 13,750 ÷ 75,000 ≈ 18.33%.
This is an estimate, not a tax return. Bracket systems, credits, social-security contributions, and state or provincial taxes all change the real figure — verify with your local tax authority before filing. Not financial advice.
FAQ
- Why does the tax calculator ask for my own rate?
- Tax brackets change every year and differ by country, state, filing status, and credits. Bundling a static table would mean the tool is out of date the day rates change. Looking up your bracket once on your local tax authority's site and pasting in the rate keeps the result accurate for any year.
- What rate should I enter — marginal or effective?
- If your country uses a flat tax, enter that flat rate. If you face progressive brackets and want a quick estimate, use your top marginal rate for a conservative figure, or a blended/effective rate from last year's return for a more realistic one.
- What does the tax year field do?
- It is a free-text note that prints into the result, the copied text, and the formula line. It does not change any calculation — it is there so you know which year a saved result applied to.
- How is the effective rate different from the rate I entered?
- The rate you enter applies to taxable income (gross − deductions). The effective rate is tax owed divided by gross income, so deductions pull it below the entered rate. The two are equal only when deductions are zero.
- Does this tool handle social security, FICA, or state tax?
- Not directly. Enter a combined rate that already includes those, or use the Paycheck Calculator for a per-period split of federal, state, and FICA.
- Is anything stored or sent to a server?
- No. All calculation runs in your browser; nothing is sent to a server or saved between visits. Closing the page clears every input.
