Your real FIRE number and timeline based on your actual savings rate.
Financial Independence, Retire Early
Your timeline under different savings rates
The FIRE movement's core insight is mathematically simple but powerful: your savings rate, not your income, determines your timeline to financial independence. Someone earning $60,000 and saving 50% reaches FI faster than someone earning $150,000 and saving 10%, purely because of the relationship between savings rate and required working years.
At a 50% savings rate with a 5% withdrawal rate, financial independence takes roughly 17 years regardless of your actual income level — because your FIRE number scales directly with your expenses, and higher income earners who maintain modest expenses reach the same multiple faster.
Lifestyle inflation is the silent killer of FIRE timelines. Every dollar of new spending after a raise both reduces your savings rate AND increases your FIRE number (since it's calculated as a multiple of expenses) — a double cost that compounds over a career.
