Savings Rate → Years to FI Calculator

The Savings Rate to Years to FI calculator cuts through one of the most persistent myths in personal finance: that a higher income is the fastest path to financial independence. What actually determines your timeline is the gap between what you earn and what you spend, your savings rate. Enter your income, expenses, current savings, and age, and the calculator instantly shows how many years stand between you and FI, along with your target number, projected FI age, and a portfolio growth chart. The sensitivity table is where it gets really useful: it maps out nine savings rate benchmarks from 10% to 70%, so you can see at a glance how dramatically shaving your expenses, not chasing a raise, compresses your timeline. The insight box quantifies it further, showing exactly how many years an extra $10,000 in annual savings buys you. Built on the 4% safe withdrawal rule and compound growth, this is the calculator that reframes the entire conversation from "how do I earn more?" to "how do I keep more?"
