How this calculator works

CD ending balance compounds the deposit for the term, then subtracts any early withdrawal penalty estimate.
Example calculation
A $10,000 CD at 4.5% for 12 months earns about $450 before any penalty or taxes.
CD Calculator FAQ
Are these retirement and investment calculators financial advice?
No. They are educational planning tools for U.S. users and do not replace advice from a qualified financial, tax, legal, or investment professional.
Why can actual investment results be different?
Actual results can differ because market returns vary, taxes change, fees apply, inflation shifts, and account rules may limit contributions or withdrawals.
