CD Calculator
Certificate of deposit maturity value, from the APY.
Certificate of deposit maturity value, from the APY. Says which constants are exact and which are conventions.
Value at maturity
$12,523.05
$2,523.05 of that is interest
A quoted APY already includes the effect of compounding, so it is the figure to compare between products — a 4.5% rate compounded daily and a 4.6% rate compounded annually are not ranked by the headline number. Breaking a CD early usually forfeits several months of interest, which this does not model.

Frequently asked questions
How much will my CD be worth?
The deposit compounded at the rate for the term. £10,000 at 4.5% for five years reaches about £12,523.
What is the difference between APR and APY?
APY includes compounding and APR does not. For deposits, APY is the honest comparison figure; a nominal rate compounded daily always yields more than the same rate compounded annually.
What happens if I withdraw early?
Most CDs charge a penalty, commonly several months of interest, which this does not model. Check the specific terms — penalties vary widely and can exceed the interest earned on a short holding.
Is a longer term always better?
Not necessarily. Longer terms usually pay more but lock the money up, and if rates rise you are stuck below market. A ladder of staggered maturities is the usual compromise.
