Tips for Your Rate
- You're above the US average — great start! Reaching 25% would put you on track for retirement before 65.
- Look for geographic arbitrage opportunities or ways to grow income.
- Maximize tax-advantaged accounts (401k, IRA, HSA) before taxable investing.
Frequently Asked Questions
Why does savings rate matter more than income?
Because your savings rate determines both how much you invest AND how much you need to live on. A person earning $50k at a 50% savings rate reaches FI faster than someone earning $200k saving 10%.
What is a good savings rate for FIRE?
Most FIRE practitioners aim for 50% or higher. At a 50% savings rate, you can reach financial independence in roughly 17 years regardless of income level.
Should I calculate savings rate from gross or net income?
Both are useful. Gross savings rate shows your total efficiency. Net (take-home) savings rate is more practical for budgeting. FIRE communities typically reference net.
Methodology
Savings Rate: Calculated as Monthly Savings ÷ Monthly Take-Home Pay × 100. The gross savings rate uses pre-tax income as the denominator.
Years to FI:Based on the formula derived from Mr. Money Mustache's "Shockingly Simple Math Behind Early Retirement." Assumes 7% real (inflation-adjusted) annual return, 4% safe withdrawal rate, and no existing savings.
What-If Scenarios: Show the reduction in working years if you increase your savings rate by the given amount, holding income constant.
