How to use this result
Even for plain deposits, the compounding assumption changes outcomes once the term gets longer. Monthly compounding and yearly compounding do not produce the same maturity amount.
This tool is for comparison and planning, not for bank disclosure replacement. Real products can differ because of preferential rate conditions, mid-term breakage rules, and tax treatment.
Use the result to compare rough options first, then verify the final yield sheet from the bank or savings institution.
Examples
One-year term deposit
Longer compound scenario
Tax planning rough check
Common questions
Q.Is tax included?
No. This calculator shows simplified pre-tax estimates unless you separately adjust for tax.
Q.Why are monthly and yearly compound results different?
Because the compounding frequency changes how often interest is added back to the balance.
Q.Does this include preferential rates?
No. Apply the rate you expect, then verify final preferential conditions with the product terms.
