G Guest May 23, 2004 #1 I need a formula to calculate compound interest capitalized monthly to a given date
N Norman Harker May 23, 2004 #2 Hi Greg! =Amount*(1+RatePerMonth)^(NoOfMonths)-Amount But if you don't have exact months you need to determine the daily effective equivalent of the monthly rate: RatePerDay=(1+RatePerMonth)^(12/365)-1 Then use: =Amount*(1+RatePerDay)^(EndDate-StartDate)-Amount Or combining the formulas: =Amount*(1+((1+RatePerMonth)^(12/365)-1))^(EndDate-StartDate)-Amount
