A FIRE tracker app that connects today’s wealth to your freedom date

The complete progress view

The metrics a FIRE tracker should keep together

Current net worth is only the starting point. A useful tracker connects the balance sheet to spending, access ages, and planning assumptions.

FIRE number

Estimate the invested assets needed from planned annual spending and a withdrawal rate you control.

Progress percentage

Compare eligible invested assets with the target rather than treating every asset as equally spendable.

Estimated FIRE date

Project a possible age and year based on savings, growth, inflation, and tax assumptions.

Accessible versus pension assets

Separate money available before retirement-account access ages from pensions and other restricted savings.

Savings rate

See how changes in annual income, spending, and contributions affect the projected timeline.

Multiple currencies

Keep international accounts in their native currencies while planning in one chosen base currency.

How to use it

Build a projection you can review

1. Add accessible and retirement assets

Include taxable investments, ISAs, brokerage accounts, pensions, 401(k)s, IRAs, and other relevant assets without confusing access dates.

2. Enter spending and savings

Use realistic annual spending and contributions. Your savings rate is one of the biggest controllable inputs.

3. Stress-test assumptions

Try lower returns, higher inflation, different retirement spending, and a more conservative withdrawal rate.

4. Review after real changes

Update after major income, spending, location, family, tax, or portfolio changes—not just when markets rise.

FIRE tracker questions

What should count toward my FIRE number?

Typically, count invested assets intended to fund retirement. Treat home equity, emergency cash, age-restricted pensions, and illiquid assets according to whether and when they can actually support spending.

Can I change the 4% rule?

Yes. The classic rule is a starting assumption, not a universal answer. Use a withdrawal rate appropriate to the expected retirement length, asset allocation, flexibility, taxes, and risk tolerance.

Does this work for expats?

PopaDex supports planning across multiple currencies. Expats should also model taxes, pension access, healthcare, and expected retirement-country spending separately.
