Retirement Calculators
Retirement planning suffers from a scale problem: the numbers are so large and the time horizons so long that intuition fails almost everyone. Is saving 10% of your income enough? What is an employer match actually worth over 30 years? How much does inflation shrink a “comfortable” nest egg between now and 2055? The calculators in this section turn those abstractions into concrete projections. You can model a 401(k) with employer matching and annual raises, project Roth IRA growth and see the value of tax-free compounding, run a full retirement projection that adjusts for inflation so the result is stated in today’s dollars, and — if early retirement is the goal — calculate your years to financial independence based on your savings rate using the math behind the FIRE movement and the 4% rule. Every projection shows its assumptions up front and lets you change them, because a retirement calculator is only as honest as the inputs it admits to. Use these tools to sanity-check your current plan, compare scenarios side by side, and find the contribution level that actually gets you to the retirement you want.
