About Standard Deduction Calculator

The standard deduction is a flat reduction from salary income requiring no proof or receipts. Its value is the amount multiplied by your marginal rate, which is why the same deduction is worth far more to a higher-rate taxpayer.

Formula

Standard deduction value

Saving = min(deduction, salary) × marginal rate

Assumptions and limits

  • The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, fees or charges or compounding frequency into account.
  • Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
  • Tax figures are estimates based on the rates, caps and thresholds you enter. Real rules differ by jurisdiction and change every year, and personal circumstances alter the outcome. This is not tax or financial advice — confirm with a qualified adviser.
  • This is an estimate for general information and not professional financial, tax or legal advice. See the full disclaimer for the limits that apply to this kind of calculator.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

Does it need supporting documents?

No. That is the point — it replaced itemised allowances with a single flat figure.

Is it available on pension income?

In many regimes yes, since pension is taxed as salary. Business income does not qualify.
