Cancer Survival Rate Estimate Calculator

Work out cancer survival rate estimate instantly with clear inputs, formula shown and shareable results.

About Cancer Survival Rate Estimate Calculator

Converts a published five-year relative survival figure into survival at any other time by assuming a constant annual hazard.

Formula

Constant hazard conversion

Annual survival = five-year survival^(1/5); survival at t years = five-year survival^(t/5); median = ln(0.5)/ln(annual survival)

Worked example

With the default values below, Cancer Survival Rate Estimate Calculator returns Estimated survival at the chosen time of 77.22%. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

  • The result is derived only from the 2 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax, 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.
  • Educational estimate only. Not a substitute for professional clinical judgement, and must not be used to make treatment or dosing decisions.
  • This is an estimate for general information and not professional medical 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

Is a constant hazard realistic?

Only roughly. Many cancers have front-loaded mortality, so early survival is lower and later survival higher than this model predicts.

What is relative survival?

Survival compared with a matched general population, which removes deaths from unrelated causes.
