How Loan Payments Are Computed
Monthly loan payments are calculated using standard amortization: M = P × [r(1+r)ⁿ] ÷ [(1+r)ⁿ−1], where P is principal, r is monthly interest rate, and n is total monthly payments.
Understanding Principal vs. Interest Split
In early loan stages, a higher fraction of each monthly installment pays interest. Over time, principal reduction accelerates, lowering the remaining debt.
Smart Strategies to Reduce Loan Interest
Making bi-weekly payments, paying extra principal each month, or refinancing at lower APRs significantly decreases lifetime interest costs.
