How this calculator works
Savings rate is the percentage of income set aside rather than spent:
Savings Rate = (Annual Savings ÷ Annual Income) × 100
- Annual Savings
- Every dollar you do not spend: 401k (pre-tax contributions count), Roth IRA, taxable brokerage, HYSA, HSA contributions — but not loan principal repayments unless you consider that "forced savings"
- Annual Income
- Use the same base consistently. Gross income is common for benchmarking against published data; net (take-home) is easier to track day-to-day
The default example uses gross income ($65,000) and 15% savings ($9,750) — roughly the amount required to max a Roth IRA and contribute enough to a 401k to capture a typical employer match.
Source: US personal savings rate data is published monthly by the Bureau of Economic Analysis (BEA). The FIRE movement's savings-rate-to-retirement-timeline math originates from Mr. Money Mustache's 2012 analysis based on the standard Trinity Study withdrawal rate of 4%.
FAQ
What is a good savings rate?
The US personal savings rate has hovered between 3–8% in recent years, so anything above 10% puts you ahead of the average. Financial planners traditionally recommend 15% (including any employer 401k match) for a standard retirement at 65. If you want to retire early, 25–50% or more is required. A 50% savings rate can get you to financial independence in roughly 17 years from scratch.
Do 401k contributions count toward my savings rate?
Yes — pre-tax 401k contributions are savings, not spending. They reduce your taxable income and grow tax-deferred. Employer match contributions can also be counted, though some prefer to track only their own contributions for a conservative picture. Roth IRA and HSA contributions count too.
What savings rate do I need to retire early?
The relationship between savings rate and years to retirement (assuming a 5% real return and 4% safe withdrawal rate): 10% ≈ 43 years · 20% ≈ 37 years · 30% ≈ 28 years · 50% ≈ 17 years · 65% ≈ 10.5 years. These assume you are starting from zero.
Should I use gross or net income?
Either works — just be consistent. Using gross income produces a lower percentage and matches published benchmarks (BEA data). Using net income is more intuitive for day-to-day tracking. If you include pre-tax 401k contributions in savings, gross income is the more accurate denominator.
