Compounding frequencies: Frequent payment and compounding schedules (e.g. bi-weekly) lower the accrued balance faster than standard monthly methods.

Compounding interest and loan payoffs

Amortization maps fixed debt repayments across compounding curves. The periodic payment is:PMT = P × r(1+r)^n / ((1+r)^n − 1).

Adding extra payments directly lowers the principal. This reduces compounding duration and overall interest charges.
