Road Accident Fatality Rate Calculator

Work out road accident fatality rate instantly with clear inputs, formula shown and shareable results.

About Road Accident Fatality Rate Calculator

Expresses road deaths both per head of population and per distance travelled, the two standard denominators in road safety statistics.

Formula

Road fatality rates

Deaths per 100,000 population = deaths / population x 100,000; deaths per 100 million vehicle km = deaths / vehicle km (millions) x 100

Worked example

With the default values below, Road Accident Fatality Rate Calculator returns Road deaths per 100,000 population of 24.000. Change any input above and every figure here is recalculated in your browser.

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, tax, fees or charges or compounding frequency into account.
  • Figures are rounded for display to 4 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

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

Frequently Asked Questions

Which denominator is better?

Population rates measure societal burden; distance-based rates measure how safe travel itself is.

Why do the two rates diverge?

A country with high mobility can have a low distance-based rate and still a high population rate.
