Savings Pace

You are investing $1,500.00/month. Over 23 years, your contributions total $402,000 before investment growth.

FIRE Target

Your FIRE target is $1,200,000 — 25× your annual expenses of $48,000. The 25× multiple corresponds to a 4% implied withdrawal rate (the widely cited "4% rule"). These are illustrative benchmarks only. Your actual sustainability depends on expenses, market returns, and retirement length.

Time to Independence

At an assumed 7% annual return, your projected portfolio reaches $1,202,729 at age 53 — your estimated FIRE age. Investment growth of $750,729 drives 62% of that value.

Disclaimer: This analysis is for illustrative and educational purposes only. Projected FIRE ages and portfolio values assume a constant annual return and consistent monthly contributions. This tool does not account for taxes, inflation, investment fees, Social Security, CPP/OAS, pension income, healthcare costs, or sequence-of-returns risk. The withdrawal rate benchmarks shown (4%, 5%, etc.) are widely cited rules of thumb — not guaranteed safe withdrawal strategies. Actual paths to financial independence will differ. This is not investment, tax, or financial advice. Consult a qualified financial advisor for personalised guidance.

How It Works

FIRE Target

FIRE Target = Annual Expenses × Target Multiple

Where Target Multiple is 20 (5% rule), 25 (4% rule), 30 (3.3% rule), or 33 (3% rule). The 25× / 4% rule is the most commonly cited benchmark.

Portfolio Growth (same formula as compound interest)

FV = P × (1 + r_m)^n + C × [(1 + r_m)^n − 1] ÷ r_m

Where P = current invested assets, C = monthly investment, r_m = effective monthly rate, n = total months.

Time to FIRE — Binary Search

Unlike a fixed-horizon calculator, this calculator solves for the time horizon itself. It uses a binary search to find the earliest month n at which FV(n) ≥ FIRE Target:

Find minimum n (months) such that: FV(n) ≥ FIRE Target
Search bounds: 1 → 1,200 months (100 years)
Not reachable: if FV(1,200) < FIRE Target

At 0% return: n = max(0, (FIRE Target − current assets) ÷ monthly investment)  [linear solve]. If monthly investment = 0 and assets are below target, the target is not reachable unless growth alone closes the gap.

Required Monthly Investment for a Target Horizon

Used for the “5 years sooner” lever and the “reach FIRE in 20 years” not-reachable suggestion:

C_required = (Target − P × (1 + r_m)^n) × r_m ÷ [(1 + r_m)^n − 1]

Effective Monthly Rate

EAR = (1 + r / n_freq)^n_freq − 1    r_m = (1 + EAR)^(1/12) − 1

Where r = nominal annual rate and n_freq = compounding periods per year (1 / 2 / 12 / 365).

Assumptions

  • Constant return rate — the nominal annual return does not change over the investment horizon.
  • Consistent monthly investment — contributions are made every month without gaps.
  • No inflation adjustment — all values are in nominal (today's) dollars.
  • No taxes or fees — growth is shown before tax and before management fees.
  • No government benefits — CPP, OAS, Social Security, and pension income are excluded.
  • No withdrawal modeling — this calculator does not model portfolio drawdown in financial independence.

The FIRE Target Multiple and withdrawal rate benchmarks are commonly cited rules of thumb — not guarantees of withdrawal sustainability.
