📈 How to Use the FIRE Calculator

Step 1: Select your currency: USD, EUR, GBP, INR, or JPY
Step 2: Input:

  • Monthly Withdrawal (e.g., €2,000)
  • Expected Annual Return (e.g., 6%)
  • Retirement Duration (e.g., 30 years)

Step 3: Get your required FIRE corpus instantly.

Step 4: Analyze the depletion curve and sustainability.

Step 5: Export your plan or share it for review.


🔢 Formula Behind the FIRE Calculation

We use the Present Value of an Annuity formula to determine your retirement corpus: Corpus=Withdrawal×[1−(1+monthlyRate)−months]monthlyRate\text{Corpus} = \frac{{\text{Withdrawal} \times \left[1 - (1 + \text{monthlyRate})^{-\text{months}}\right]}}{\text{monthlyRate}}Corpus=monthlyRateWithdrawal×[1−(1+monthlyRate)−months]​

Where:

  • Withdrawal = Fixed Monthly Amount
  • monthlyRate = Annual Return ÷ 12
  • months = Years × 12

This formula ensures your money lasts exactly the number of years you specify—backed by compound math.
