Formula to solve interest rate
To calculate a payment the number of periods (N), interest rate per period (i%) and present value (PV) are used. For example, to calculate the monthly payment R = interest rate (in percentage). T = time duration (in years). Inorder the calculate the total amount, the following formula is used: Amount (A) = Principal (P) + 16 Jul 2018 The average credit card interest rate in the summer of 2018 was 17% APR. If you owe $5,000 in credit card debt and make only the 4% minimum 15 Sep 2014 To find the interest rate (r) in the formula a=p(1+r)t , you need to know the values of a (amount), p (principal) and t (time). You would take a and

How to calculate the Simple Interest Formula, how to solve interest problems using the simple The Interest Rate (r) is a percent of the principal earned or paid. Covers the compound-interest formula, and gives an example of how to use it. For instance, let the interest rate r be 3%, compounded monthly, and let the initial all the values plugged in properly, you can solve for whichever variable is left.
To calculate interest rate, start by multiplying your principal, which is the amount of money before interest, by the time period involved (weeks, months, years, etc.). Write that number down, then divide the amount of paid interest from that month or year by that number. The answer is your interest rate, but it will be in decimal format.

If you can solve this to obtain A, B and C, you have found your r = rate of interest per interest period (e.g., 10% per year) t = number of Solution : For first fund: I1 = P1r1t1. I1 = P1 (.07)(1) For second fund: I2 = P2r2t2. I2 = P2
