This calculator provides estimates for educational purposes only. It is not a bank quote, tax advice, legal advice or personalized financial advice. Actual earnings and penalties depend on the financial institution's terms, compounding method, dates, taxes and rounding.

Compare multiple CD assumptions

When to use the CD comparison calculator

Use this calculator when you have two or three certificate of deposit offers and want to compare projected maturity value, estimated interest and lockup time using the same basic assumptions.

Inputs explained

Each offer uses a deposit amount, APY and term in months. Optional tax inputs estimate after-tax interest, but they do not replace tax advice.

  • Use matching deposit amounts for a cleaner comparison.
  • Use matching terms when you want a direct APY comparison.
  • Use different terms when lockup time is part of the decision.

Example scenario

A 12-month CD with a lower APY may be easier to compare with an 18-month CD when you can see both the ending balance and the extra months your money is locked up.

How to interpret the results

The table highlights projected returns and shortest lockup period, but it does not label one CD as best overall because liquidity, penalties, minimum deposit rules and renewal terms can change the decision.

Limitations

The comparison does not use live bank rates and does not verify offer availability. Always confirm the official APY, term, minimum balance, fees and early-withdrawal penalty with the institution.
