Formula used
- Annual expenses today = monthly expenses x 12.
- FIRE number today = annual expenses / safe withdrawal rate.
- Current progress = current investments / FIRE number today x 100.
- Every projected month, corpus grows by expected monthly return and monthly investment is added.
- Every projected year, expenses grow by the expected inflation rate.
- Projected FIRE number = projected annual expenses / safe withdrawal rate.
- Real return estimate = (1 + return) / (1 + inflation) - 1.
- Taxes, market volatility, changing expenses, asset allocation, and sequence-of-return risk are not included.
Quick answers
FIRE Number Calculator FAQs
What is a FIRE number?
A FIRE number is the estimated investment corpus needed for financial independence, often calculated from annual expenses and safe withdrawal rate.
How is FIRE number calculated?
A common formula is annual expenses divided by safe withdrawal rate. For example, lower withdrawal rates require a larger corpus.
Does the FIRE calculator include inflation?
Yes, it can inflate current expenses using the entered inflation rate before estimating future corpus needs.
Is the safe withdrawal rate guaranteed?
No. Safe withdrawal rate is an assumption and can vary by market returns, retirement duration, taxes, asset mix, and spending flexibility.
