Use your real deposit amount
A rate may look attractive but may not apply if your deposit is below the product minimum.
Entering your intended amount helps the calculator keep the result practical.
Compare gross and net views
Gross interest shows the rate before a withholding-tax-style deduction. A net view helps you plan the interest you may actually keep.
