Discover your savings rate and how many years until financial independence. Enter your net income, savings or expenses, starting balance, and expected investment return — results update instantly.
Savings rate is the percentage of net (after-tax) income saved or invested: (income − expenses) ÷ income × 100, or savings ÷ income × 100. Higher rates shorten years to financial independence (FI) under the 4% rule — FI number ≈ annual expenses × 25, implying ~4% safe withdrawal. Years to FI iterate compound growth: each year balance = balance × (1 + return) + annual savings until balance ≥ FI target. A 50% savings rate on $80,000 net with $40,000 expenses targets ~$1M FI; starting at $0 and 7% return often reaches FI in roughly 17–18 years versus 40+ years at 15% savings rate. FI timelines lengthen sharply when returns fall below assumptions or lifestyle inflation raises expenses after raises. Employer retirement matches and pension accruals should be included in savings numerators for a complete picture. Emergency funds and insurance needs may require parallel cash buffers beyond invested FI assets.
Worked example: Net $6,000/month, save $2,100 → rate = 35%. Expenses $58,800/year → FI target ≈ $1.47M. With $50,000 starting balance and 7% return, independence might arrive in about 22–24 years depending on contribution growth.

Evidence-based strategies to accelerate FI.
Savings rate is the primary lever under your control for FI timeline — more powerful than chasing extra return. FI date assumes stable expenses and sustained employment; life events add variance. Treat timeline as motivation, not certainty.
Increasing your savings rate by just 1 percentage point per year compounds dramatically. A household saving 15% today that adds 1% annually reaches 25% in a decade — potentially cutting years off their FI timeline without a single painful budget overhaul.
Cutting expenses has a double effect: it raises your savings rate immediately and lowers your FI number (25× expenses). Earning more helps too, but only if lifestyle inflation doesn't consume the raise. Track both levers with this calculator.
Financial independence traditionally means having 25× annual expenses invested, allowing a 4% annual withdrawal. At a 50% savings rate, you can reach FI in roughly 17 years from zero — one of the most powerful levers in personal finance.
Savings rate and FIRE math explained.
20% is the classic healthy baseline (50/30/20 rule). 30–50% puts you on a fast FI track. Below 10% is risky — you may never reach financial independence without major changes to income or spending.
We apply the 4% safe withdrawal rule: FI number = 25 × annual expenses. Your portfolio grows each year with compound returns plus new savings until it hits that target. Starting balance is included.
Use whichever matches your budget. The calculator converts everything to annual figures internally for consistent FI projections.
7% is a common long-term assumption for a diversified stock index portfolio (after inflation, opinions vary). Conservative planners use 5–6%; historical S&P averages are higher but not guaranteed.
