This free FI / FIRE calculator estimates your financial independence number — the investment corpus needed so safe withdrawals can cover living expenses without earned income. Adjust age, income, expenses, savings, inflation, and return assumptions to see years-to-FI, gap to target, and which FI path (Lean, Coast, Traditional, or Fat) you are closest to for 2026.
If you spend about ₹60,000 a month (₹7,20,000 a year), a classic 25× traditional FI target is about ₹1,80,00,000 in today's money. Use the sliders above to match your surplus, current investments, and withdrawal-rate assumptions — then stress-test with Pro Mode (tax haircut, SORR shock, and spending step-down).
The model uses constant rates for returns, inflation, income growth, and withdrawal assumptions. Pro Mode adds estimation layers (tax, sequence-of-returns risk, and post-retirement step-down), but real outcomes still vary with markets, taxes, and spending shocks. Treat outputs as a planning baseline for 2026, not a guarantee.
What is a Financial Independence (FI) number?
Your FI number is the investment corpus needed so that withdrawals at a safe rate (commonly 4%) cover your annual expenses indefinitely. This calculator estimates that number for 2026 and projects when you might reach it across India, the US, and the UK.
How does the safe withdrawal rate affect my FI number?
A lower safe withdrawal rate (e.g. 3%) means you need a larger corpus but have a higher margin of safety. A higher rate (e.g. 5%) lowers the target but increases the risk of running out of money.
What does Pro Mode add in this FI calculator?
Pro Mode lets you stress-test your plan with average tax rate on returns, a one-time Year 1 sequence-of-returns-risk (SORR) shock, post-retirement expense step-down, retirement-age marker, and an optional leave-behind target.
What is SORR and how does it impact FI outcomes?
SORR stands for Sequence of Returns Risk: the risk that poor market returns arrive early in your journey or early in retirement. Even if long-term average returns look fine, an early negative shock can permanently reduce compounding because your corpus has less capital left to recover from. In this calculator, SORR is modeled as a one-time Year 1 return shock in Pro Mode and also increases the FI target as a safety buffer. More negative SORR assumptions generally push FI age later and require a larger corpus to reduce the probability of running out of money.
Does savings rate really matter that much?
Yes. Savings rate is the single most powerful lever for reaching FI faster. A higher savings rate both increases the amount you invest and decreases the lifestyle your portfolio needs to sustain.
Is this tool financial advice?
No. It is a scenario-based planning tool that gives indicative estimates. Real outcomes depend on market returns, tax rules, spending changes, and individual circumstances. Consult a qualified advisor.
After you size the FI number, model accumulation with SIP and drawdown with SWP / retirement tools.
