About the Retirement Calculator

The Retirement Calculator projects your retirement pot from current savings, monthly contributions and expected returns, then checks it against your target income. It runs as plain JavaScript inside the page, which means there is no upload step, no queue and no size limit imposed by a server — the only limit is your own device.

What people use it for

  • Checking whether your current saving rate is anywhere near enough.
  • Seeing how five more working years changes the outcome.
  • Setting a monthly target from a retirement income goal.
A projection is not a plan. Returns are not smooth, inflation varies, and life happens. Re-run this every year with real numbers rather than trusting a single forecast made once.

Frequently asked questions

Are there any usage caps on the Retirement Calculator?
There is no cost and no cap. The Retirement Calculator is not a demo of a paid product, so nothing is held back or watermarked.
Is the Retirement Calculator safe to use with private information?
No. The Retirement Calculator runs entirely in your browser using JavaScript. Because the work happens locally, the tool also keeps working if your connection drops, and closing the tab is all it takes to discard everything.
What is the Retirement Calculator used for?
Typical uses: checking whether your current saving rate is anywhere near enough. Seeing how five more working years changes the outcome. Setting a monthly target from a retirement income goal. It is built for exactly those cases rather than being a general-purpose tool with this bolted on.
Is there a catch?
A projection is not a plan. Returns are not smooth, inflation varies, and life happens. Re-run this every year with real numbers rather than trusting a single forecast made once.
Can I rely on this for exact work?
The calculation runs in double precision and the result is shown to ten significant figures, so converting a value and converting it back returns the original. What is displayed is rounded for readability; what is copied is not.
