How to use

Enter the values requested above. Estimate total deposits, pre-tax interest, and the maturity amount for equal monthly contributions at a stated annual rate. The result is calculated in your browser.

Formula

Deposited principal = monthly deposit × months. Estimated interest sums each deposit's remaining earning months at the annual rate.

Example

What if you deposit KRW 100,000 monthly for 12 months at 12%?

Deposits total KRW 1,200,000. With end-of-month deposits and simple interest, estimated pre-tax interest is KRW 66,000.

Frequently asked questions

When is each monthly deposit treated as made?
This estimate treats deposits as made at the end of each month, so the final deposit earns no interest in the period.
