Deposit Interest Calculator
Calculate gross and net deposit returns based on principal, term, annual rate, and withholding/deduction rate.
Formula
Gross return = principal × annual interest rate × days / 365; Net return = gross return - withholding
Source / method note
The calculation is based on the simple term deposit return formula: gross return = principal × annual interest rate × days / 365. Bank campaign rates, central bank market data, and withholding practices may change periodically, so rates are left as user inputs.
Legal / official rate note
This tool is prepared for informational estimation purposes. For net return, withholding, term, currency, bank campaign conditions, and tax practices, the bank's current offer and applicable legislation should be based.
