How Loan Calculations Work

Understanding the mathematics behind loan payments

Monthly Payment Formula

Monthly payments are calculated using the standard loan formula: M = P × [r(1+r)ⁿ] / [(1+r)ⁿ - 1]

Where M = Monthly Payment, P = Principal, r = Monthly Rate, n = Number of Payments

Amortization Schedule

Each payment is split between principal and interest. Early payments have more interest, while later payments have more principal as the balance decreases.

Extra Payments

Extra payments go directly toward principal, reducing total interest and shortening the loan term. Even small extra payments can save thousands over the loan life.

Interest Calculation

Interest is calculated monthly on the remaining balance. The annual rate is divided by 12 to get the monthly rate, then multiplied by the current balance.

Loan Management Tips

Smart strategies to save money on your loans

Make Extra Payments

Even $50 extra per month can save thousands in interest and years off your loan term.

Compare Rates

Shop around with multiple lenders. A 0.5% rate difference can save thousands over the loan life.

Bi-weekly Payments

Making payments every two weeks instead of monthly can cut years off your loan.
