Frequently Asked Questions

What is the future value formula?

FV = PV × (1 + r)ᵗ, where PV is the amount invested, r the annual return as a decimal and t the number of years.

Why is the inflation-adjusted figure so much lower?

Because inflation compounds too. At 6% inflation, prices double roughly every 12 years, so a nominal 8% return is only about 1.9% in real terms. The real value is what tells you whether you actually got richer.

What is CAGR?

Compound annual growth rate — the single constant rate that would take your starting value to your ending value over the period. The reverse mode calculates it from two values and a time span.

Are these projections guaranteed?

No. The calculator compounds the rate you enter; it has no view on markets. Real returns fluctuate, can be negative in any given year, and past performance never guarantees future results.
