Some lending institutions calculate the monthly payment $M$ on a loan of $L$ dollars at an interest rate $r$ (expressed as a decimal) by using the formula $$M=\frac{L r k}{12(k-1)}$$ where $k=[1+(r / 12)]^{12 t}$ and $t$ is the number of years that the loan is in effect.

Key Concepts

Compound Interest

Compound interest refers to the process where interest is calculated not only on the initial principal but also on the accumulated interest from previous periods. In finance, it is widely used to determine how loans and investments grow over time, especially when the interest is compounded at regular intervals such as monthly or annually.

Loan Amortization

Loan amortization is the method of repaying a loan through a series of regular, fixed payments over a specified time period. Each payment includes both interest and a contribution towards reducing the principal balance, leading to gradual repayment of the debt until it is fully paid off.

Annuity Payment Formula

The annuity payment formula is a mathematical expression used to determine the fixed periodic payment required to fully repay a loan or investment over time. This formula takes into account the interest rate, the total number of payments, and the principal amount, ensuring that the sum of all payments matches the loan's value plus accrued interest.

Total Interest Calculation

Total interest calculation involves determining the overall amount of interest paid over the life of a loan. This is typically done by multiplying the periodic payment by the total number of payments and then subtracting the original loan principal, providing insight into the true cost of borrowing.
