The amount you deposit into the CD.
The CD's stated annual interest rate.
A = final balance, P = principal, r = annual rate (decimal), n = compounding periods per year, t = term in years. APY reflects the true annual yield including compounding.
A = P × (1 + r/n)^(n×t)A $10,000 CD at 4.5% for 1 year compounded monthly yields about $459 in interest. A typical high-yield savings account at 4% yields ~$408 — the CD wins if you can lock funds.
Locking $10,000 into a 5-year CD at 4.5% compounded monthly results in over $2,500 in interest, compared to just $459 for a 1-year CD at the same rate.
