FIRE Accumulation Calculator

Calculate your time to Financial Independence

Parameters

Simulation Mode

Historical uses real past data (deterministic). Monte Carlo randomizes years to create new hypothetical scenarios.

Current Net Worth ($)

Total value of all your investments (401k, IRA, brokerage, etc). Don't include home equity unless you plan to sell.

Track your net worth with Empower

Annual Savings ($)

How much you save and invest each year, after taxes. The higher this is relative to your spending, the faster you reach FI.

Your savings rate is what accelerates your path to FI

Retirement Lifestyle

Enter your desired after-tax spending (money in your pocket). We'll gross it up for taxes and calculate your FI target using a 4% safe withdrawal rate.

Desired Annual Spending (today's $)

After-tax spending money in your pocket, inflation-adjusted

Your FI Target:$1,500,000

If you retired today:30.0% withdrawal rate (Very risky)

Coast FIRE

Stop saving after a certain year and let your portfolio grow from market returns only. Calculate when you'll reach FI by coasting.

Stop saving early and let market growth do the rest

Taxes & Fees

These reduce your effective returns. Tax rate affects how much you need to withdraw to get your desired spending. Fees drag on portfolio growth.

Tax Rate (%)

Most retirees see 10-22% effective rates

20% off H&R Block tax filing

Investment Fees (%)

Annual expense ratio

How Long Until Financial Independence?

The FIREwiz accumulation calculator estimates how many years it will take to reach Financial Independence based on your current savings, annual contributions, asset allocation, and target FIRE number. Instead of assuming a fixed rate of return, it runs hundreds of simulations using actual historical market data (1928–2023) to show you a range of outcomes.

See the probability of reaching your FIRE number at different time horizons, along with portfolio percentile paths so you can understand best-case, median, and worst-case trajectories. Adjust your savings rate or allocation and watch the projections update in real time.

Considering Coast FIRE? Enable the Coast FIRE option to find the portfolio balance at which you can stop contributing and let compound growth carry you to your goal by a target retirement age. All projections are shown in today's dollars so your FIRE number means the same thing regardless of when you reach it.
