A loan's APR can be found using a formula and following a few steps. First, add the loan's fees and interest together. You'll then divide it by the principal and again by the number of days in the repayment term. Then multiply by 365 and again by 100.

A weighted average interest rate is an average that is adjusted to reflect the contribution of each loan to the total debt. The weighted average multiplies each loan's interest rate by the loan balance and divides the sum by the total loan balance.

How to calculate discount rate. There are two primary discount rate formulas - the weighted average cost of capital (WACC) and adjusted present value (APV). The WACC discount formula is: WACC = E/V x Ce + D/V x Cd x (1-T), and the APV discount formula is: APV = NPV + PV of the impact of financing.

Here's the formula for the annual interest rate: Annual interest rate = [1 + (i / n)]n - 1, where 'n' is the number of periods and 'i' is the nominal interest rate.

To calculate a real interest rate, you subtract the inflation rate from the nominal interest rate. In mathematical terms we would phrase it this way: The real interest rate equals the nominal interest rate minus the inflation rate.

To calculate APR, use the following steps: Calculate the interest rate. Add the administrative fees to the interest amount. Divide by loan amount (principal) Divide by the total number of days in the loan term. Multiply all by 365 (one year) Multiply by 100 to convert to a percentage.

To calculate the weighted average interest rate of all your loans, multiply each loan amount by its interest rate. Add the results together, then divide that number by the sum of all your loan balances. Whatever that figure is, round up to the nearest 1/8 of a percent.

The formula and calculations are as follows: Effective annual interest rate = (1 + (nominal rate ÷ number of compounding periods)) ^ (number of compounding periods) - 1. For investment A, this would be: 10.47% = (1 + (10% ÷ 12)) ^ 12 - 1. And for investment B, it would be: 10.36% = (1 + (10.1% ÷ 2)) ^ 2 - 1.
