About MyWealthCheck

Last updated: 2026-11-09

MyWealthCheck builds free planning tools for people working towards financial independence, wherever they live. The goal is simple: help you answer "am I on track?" with your own numbers, in your own currency, without handing them to anyone.

What you can do here

  • FIRE calculator: your FIRE number, the monthly investment to retire early, your earliest FI age and Coast FIRE number.
  • Retirement calculator: how much you need to retire and the monthly investment that gets you there.
  • Financial planner: your FIRE number, how much to invest each month, the earliest age you could be financially independent, and how to manage the money after FI, including in a market crash.
  • Plan goals such as a child's education or a house, and check year by year whether it all fits your income.
  • Guides: plain-English explanations of FIRE, the 4% rule and the maths behind the tools.

How we work

  • Private by design. Calculations run in your browser. Your inputs are not sent to our servers.
  • Global by default. Any currency, shown the way it's written locally, with country presets for inflation, returns and pension accounts (including EPF, PPF and NPS in India, with lakh and crore).
  • Conservative and tested. Returns are after tax and set conservatively. The calculation code has automated tests covering scenarios in several countries.
  • Education, not advice. We suggest types of products, never specific funds. See the disclaimer.
