About Retirement Date Calculator

Retirement date is the birthday on which the target age is reached, so someone born 18 June 1975 retiring at 67 reaches it on 18 June 2042. From 4 September 2026 that is 15.8 years, or about 189 months of contributions remaining - the figure that pension projections compound over.

Formulas

Retirement date

date = birth date with the year advanced by the retirement age

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 2 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

Is state pension age the same as retirement age?

Not necessarily. State pension age is set by legislation and rising in many countries, while personal retirement is a financial decision.

Why do the months matter more than the years?

Because contribution projections and annuity quotations work monthly, so the exact month count changes the final figure.
