CD Interest Formula

A = P × (1 + r/n)^n×t

A = Maturity value (final amount)

P = Principal deposit amount

r = Annual interest rate (APY as decimal)

n = Compounding frequency per year (365)

t = Time in years

CD Ladder Strategy: By splitting your deposit across multiple CDs with staggered maturity dates, you maintain regular access to portions of your funds while earning higher rates on longer-term CDs. As each short-term CD matures, you can reinvest it into a new long-term CD.

Frequently Asked Questions

What is a CD (Certificate of Deposit)?▾

A CD is a savings product where you deposit money for a fixed term at a guaranteed interest rate. CDs typically pay higher rates than savings accounts but funds are locked until maturity.

What is a CD ladder?▾

A CD ladder splits your deposit across multiple CDs with staggered maturity dates. This provides regular access to funds while capturing higher long-term rates.

What happens if I withdraw a CD early?▾

Early withdrawal typically incurs a penalty of 3-12 months of interest depending on the CD term. Some banks offer no-penalty CDs with slightly lower rates.
