The CD maturity value formula
A = P (1 + APY)^t
P is the initial deposit, APY is the advertised annual percentage yield (already accounting for compounding), t is the term in years. For sub-year terms, use the equivalent fraction of a year.
Worked example
A $10,000 deposit in a 24-month CD at 5.00% APY: A = 10,000 × (1.05)^2 = $10,250 at the end of year 1, $10,762.50 at maturity. Total interest earned: $762.50.
Frequently asked questions
What is the early withdrawal penalty?
Typically 3 months of interest for terms under 1 year, 6 months for 1–5 year CDs, and 12 months for longer. Some CDs penalize principal if you withdraw before earning enough interest to cover the fee.
Are CD rates better than high-yield savings?
In early 2026, top CDs pay 4.8–5.0% APY for 12-month terms vs. 4.0–4.5% on high-yield savings. The trade-off is liquidity — you commit the money for the term.
Should I use a CD ladder?
A CD ladder staggers maturities (e.g., 1-, 2-, 3-, 4- and 5-year CDs) so a portion matures each year. Provides liquidity while capturing longer-term yields.
