To calculate an estimate of the doubling time, divide 72 by the interest rate. For example, for an investment earning 4%, it will take about 18 years (72/4) for the investment to double in value.

Use this simple interest calculator to find A, the Final Investment Value, using the simple interest formula: A = P(1 + rt) where P is the Principal amount of money to be invested at an Interest Rate R% per period for t Number of Time Periods.

The simple interest formula is I = P x R x T. Compute compound interest using the following formula: A = P(1 + r/n) ^ nt. Assume the amount borrowed, P, is $10,000. The annual interest rate, r, is 0.05, and the number of times interest is compounded in a year, n, is 4.

Compounding Daily Interest To calculate the daily compounding interest on a $10,000, 10% note for 90 days (please allow for rounding differences): Convert the percentage rate to a decimal: 10 ÷ 100 = 0.10. Convert the annual rate to a daily rate: 0.10 ÷ 365 = 0.00027397.

Time = (100 × Interest)/(Principal × Rate) Therefore, Time (T) = 10 years.

The interest, typically expressed as a percentage, can be either simple or compounded. Simple interest is based on the principal amount of a loan or deposit. In contrast, compound interest is based on the principal amount and the interest that accumulates on it in every period.

The formula for calculating compound interest is P = C (1 + r/n)nt – where 'C' is the initial deposit, 'r' is the interest rate, 'n' is how frequently interest is paid, 't' is how many years the money is invested and 'P' is the final value of your savings.

P = the principal investment amount (the initial deposit or loan amount) r = the annual interest rate (decimal) n = the number of times that interest is compounded per unit t. t = the time the money is invested or borrowed for.

To compute daily interest for a loan payoff, take the principal balance times the interest rate and divide by 12 months, which will give you the monthly interest. Then divide the monthly interest by 30 days, which will equal the daily interest.
