How does compound interest grow savings?
With compound interest, the interest earned each period is added to the balance and earns interest itself, so savings grow faster over time.
Saving the same monthly amount for 20 years ends up with far more than double what 10 years gives. The savings and compound interest calculators show this year by year; the simple interest calculator covers short-term sums where interest is paid on the principal only.

How does inflation affect savings and retirement?
Inflation erodes purchasing power: if your return is below inflation, your savings shrink in real terms even as the number grows.
The inflation calculator shows what an amount will buy in future, and the retirement and annuity calculators show savings and income in today’s money.
How do you measure an investment’s return?
Return is measured two ways: return on investment (ROI) is total gain divided by the starting amount, and the compound annual growth rate (CAGR) is the average yearly rate behind that gain.
CAGR is the fairer measure when comparing investments held for different lengths of time.
