How to Calculate Hourly Compounding Interest

Determine the value of the following amounts: the initial value of the loan, the hourly compound interest rate, and the number of hours that have elapsed since compound interest began accruing. These three values correspond to the variables L, i and h respectively.

Insert these values into the following formula: L times (1 + i)^h = F. F represents the total amount owed on the loan, including the compound interest.

Solve the formula for F. If you only want to know the amount of interest that has accrued independent of the initial value of the loan, subtract the value of L from the value of F.
