Retirement Date Estimator
Calculates a target retirement date from date of birth and retirement age, with approximate working days and time left.
What this means
Time left: 28y 7m. Retiring 2 years earlier requires saving enough to cover fewer working days.
Formula used
Retirement date = DOB plus target age years. Working days remaining approx years * working_days_per_year.
Worked example
DOB 1 Jan 1990, target 65 => 1 Jan 2055. From 18 May 2026 about 28y 7m left.
Common questions
Can I use this internationally?
Yes. Currency selectors are display-only unless a tool explicitly says otherwise; no currency conversion is performed.
How exact is the result?
It follows the published Technofatty formula for this tool, but real life can add fees, rules, timing quirks, and context.
Plain-English summary
Target retirement date: 01 Jan 2055. 6500 working days left.
This section translates the result into a short, direct takeaway rather than leaving the page at a bare number.
