How cd is calculated
The projection compounds once per year at the rate entered. It does not look up a market yield or official inflation series. Formula: Maturity value = deposit × (1 + annual rate)^term. Use the displayed details to inspect the intermediate amounts and replace example assumptions with terms from your own quote or records.
Maturity value = deposit × (1 + annual rate)^term.A $10,000 deposit at 4% for 2 years with annual compounding becomes $10,816.
Assumptions & useful context
The result depends on the values you enter and the method described above. Displayed numbers may be rounded; calculations use the unrounded values. Check that this model matches your situation before relying on it.
Financial projections use your assumptions. Actual returns, lender terms, fees and tax rules can differ; these results do not guarantee a future outcome.
Frequently asked questions
CD Calculator: what does the result include?
Simple interest is computed on the original principal only. Compound interest also earns returns on previously credited interest.
CD Calculator: which assumptions matter most?
No. You supply the annual assumption, so the result is a what-if calculation rather than a historical index lookup or bank quote.
