CD Calculator
CD maturity balance and interest from principal, rate, term and compounding.
How it works
Balance = P × (1 + r ÷ n)^(n × t)
A CD earns a fixed rate for a set term; more frequent compounding yields a higher balance.
Worked example
Principal 50,000 at 3% for 2 years:
- Annual compounding:
50000 × 1.03² = 53,045, interest 3,045 - Monthly compounding:
50000 × (1+0.0025)²⁴ ≈ 53,088, interest 3,088
More frequent compounding adds a little, but not much.
Notes and limitations
CDs usually carry an early-withdrawal penalty (interest drops to the demand rate), so liquidity is limited. Compare products on rate, compounding method and withdrawal terms — not the headline rate alone.
