CD Calculator
Calculate CD, money market and high-yield savings earnings — APY growth broken down by year.
The Years/Months dropdown just sets how the term number is counted — e.g. "5" + "Years long" is a 5-year term, while "5" + "Months long" is a 5-month term.
Growth by Year
| Year | Interest to Date | Balance |
|---|---|---|
| 1 | +$450.00 | $10,450.00 |
| 2 | +$920.25 | $10,920.25 |
| 3 | +$1,411.66 | $11,411.66 |
| 4 | +$1,925.19 | $11,925.19 |
| 5 | +$2,461.82 | $12,461.82 |
CDs usually charge an early-withdrawal penalty (often several months of interest) if you cash out before the term ends.

What Is the CD Calculator?
The CD Calculator shows how much a certificate of deposit, money market account or high-yield savings account will earn. Enter your deposit, rate (APY or nominal APR with compounding) and term to see the ending balance, total interest and a year-by-year growth table. The money market mode adds monthly deposits to model an account you keep funding.
How It Works
Pick CD (single deposit) or Money Market/Savings (with monthly deposits), enter the amount, rate and term, and the results update instantly with a growth-by-year breakdown.
When to Use It
Use it to compare CD offers at different banks, see whether a longer term is worth it, or project a high-yield savings balance with regular contributions.
Frequently Asked Questions
- What's the difference between APY and APR?
- APR is the nominal annual rate before compounding; APY is the effective yield after compounding. Banks advertise APY for deposits — if you have an APR, choose the compounding frequency and the calculator converts it.
- CD vs. money market — which pays more?
- CDs usually pay a slightly higher rate in exchange for locking your money for the term; money market accounts pay a bit less but let you add and withdraw money. Run both modes to compare.
