Planning Formulas

Quick answer: retirement planning usually combines compounding growth, future spending estimates, and a withdrawal-rate assumption.

  • Future value of current savings: FV = PV × (1 + r/n)^(n×t)
  • Future value of recurring contributions: annuity-based compounding over time
  • Inflation-adjusted income target: Future Need = Current Need × (1 + i)^t
  • Nest egg estimate: Target Portfolio = Needed Annual Income ÷ Withdrawal Rate
  • Projected annual income: Portfolio × Withdrawal Rate
Where PV = present value, r = annual return, n = compounding frequency, t = years, and i = inflation rate.

FAQ

What does this retirement calculator estimate?

It estimates how much your savings may grow by retirement, how much annual income that balance may support, and whether that lines up with your target retirement income.

Why include inflation?

Because future expenses usually cost more than they do today. Inflation helps convert today’s income goal into a future-dollar target.

What is a withdrawal rate?

A withdrawal rate is the percentage of your portfolio you plan to withdraw each year in retirement. A common planning example is 4%, though real decisions depend on risk, taxes, market conditions, and lifespan.

Does this replace professional advice?

No. This tool is for planning estimates. Taxes, fees, sequence-of-returns risk, pensions, Social Security timing, healthcare costs, and real-life spending patterns can materially change outcomes.
