How the Inflation Calculator works

Inflation erodes the purchasing power of money over time — the same dollar buys less each year. This calculator shows how much a sum today will be worth in the future (or how much past money is worth now) at a given inflation rate.

Formula

Future cost = Present amount × (1 + i)ⁿ

i is the annual inflation rate (decimal) and n is the number of years. To find what a future amount is worth in today's money, divide instead of multiply: today's value = future amount ÷ (1 + i)ⁿ.

Worked example: $1,000 of goods at 3.5% inflation over 20 years

  1. Present amount = 1,000; i = 0.035; n = 20.
  2. (1 + i)ⁿ = 1.035²⁰ ≈ 1.9898.
  3. Future cost = 1,000 × 1.9898 ≈ $1,990.
  4. What costs $1,000 today would cost about $1,990 in 20 years — purchasing power nearly halves.

How to read the result

Inflation is why money kept in cash loses value and why long-term savings need to earn more than the inflation rate just to stay even. Use it to set retirement and college targets in realistic future dollars.

Common mistakes to avoid

  • Planning long-term goals in today's prices without inflating them forward.
  • Assuming a fixed inflation rate; it varies year to year.
  • Confusing nominal returns (before inflation) with real returns (after).

Frequently Asked Questions — Inflation Calculator

Because rising prices reduce what money buys, your savings must earn more than inflation just to maintain purchasing power. Only returns above inflation represent real gains.
Long-run averages in many economies sit around 2–4%. Using a slightly conservative (higher) rate makes long-term plans more robust.
Nominal return is the headline rate; real return subtracts inflation. A 7% nominal return at 3% inflation is about a 4% real return.
