Deposit calculator

Calculate deposit earnings without compounding: accrued interest and the final amount at the end of the term.

Calculation parameters

Term unit

Amount at end of term

100000 • 12 mo. • 12% =
112000
12% annual rate
# Deposit amount 100000
Accrued interest 12000
= Final amount 112000
Formula: I = P × R / 100 × T P is the initial amount, R is the annual rate, and T is the term in years
How it works This is a simple-interest calculation without compounding: earned interest is not added to the base for later interest.

Explanation and example

The calculator uses simple interest. When the term is entered in months, the number of months is divided by 12 and the annual rate is applied proportionally to that fraction of a year.

For example, a deposit of 100,000 at 12% annual interest for 12 months:

100000 × 12 / 100 × 1 = 12000
Accrued interest is 12,000 and the final amount is 112,000.
More examples 100,000 at 12% for 12 months → 112,000 50,000 at 10% for 6 months → 52,500 80,000 at 7.5% for 2 years → 92,000 30,000 at 0% for 12 months → 30,000
Does this calculator compound interest?

No. This calculator is for a simple deposit calculation without compounding. Compound interest is handled by a separate calculator.

Are taxes or bank fees included?

No. The result shows the mathematical accrual at the entered rate before taxes, fees and other deductions.

How is a term in months calculated?

A term in months is converted to a fraction of a year by dividing the number of months by 12.

Can I use a decimal interest rate?

Yes. You can enter the rate using either a dot or comma as the decimal separator.

Is the result an exact bank quote?

No. Actual accrual can depend on the bank’s day-count method, taxes, fees, early withdrawal rules and other terms.
