A Series of Deposits End of the Monthįor recurring monthly deposits where deposits are made at the end of each month you would use the following calculation.Īll the definitions in this formula are the same as the definitions in the first formula, except PMT is the monthly deposit. To find the interest which was earned from the account all you would need to do is subtract the initial deposit amount from the end result. n = number of times interest is compounded per year.r = annual interest rate, as a decimal rather than percent (also called APR).The above calculator automatically does this for you, but if you wanted to calculate compound interest manually the formula is The hard way would be manually calculating the returns. The easy way to do this is to use the above calculator. How Inflation is Accounted ForĪfter taxes are deducted from interest earnings & final savings are calculated, inflation is accounted for by multiplying the final amount by (100% - inflation rate) years If your account is untaxed then enter zero as the marginal tax rate in the above calculator. Ordinary interest on a regular bank savings account is typically paid for on an annual basis, with banks sending account holders a 1099-INT if they earn above some baseline level of around $10. This approach is how tax payments would work on savings stored inside a tax deferred retirement account.

This calculator estimates taxes based on the rate entered with the tax payment made at the end of the investment period. If you would like to end money at the end of each month then you would subtract the regular contribution amount from the initial savings to calculate interest at the end of the month. In the above calculator when recurring account contributions are made, money is added or subtracted at the beginning of each month, week, or other selected period. If you would like to change the compounding frequency for a one-time deposit then set the "deposit each cycle" variable to $0 and select "transaction frequency" at whatever frequency you wish to compound interest. Most bank savings accounts use a daily average balance to compound interest daily and then add the amount to the account's balance monthly, which is mathematically quite similar to monthly compounding. If the account has a lump-sum initial deposit & does not have any periodic deposit, by default interest is compounded monthly. Our calculator compounds interest each time money is added.
