The Power of Principal Prepayments

When you take out a mortgage, car loan, or personal loan, your standard monthly payment is divided between paying off the **interest** (the cost of borrowing the money) and the **principal** (the actual amount borrowed).

How Prepayments Accelerate Payoff

In the early years of a long-term loan (like a 30-year mortgage), the majority of your payment goes to interest. However, when you make an **extra payment**, 100% of that additional money is applied directly to the **principal balance**. By reducing the principal early, you permanently lower the balance on which interest is computed in all future months, resulting in substantial interest savings and a shorter term.

Bi-Weekly Payment Strategy

Making bi-weekly payments is a popular acceleration strategy. By paying half of your monthly payment every two weeks, you make 26 half-payments in a year, which equals 13 full payments instead of 12. This extra payment each year can shave years off your loan without putting a major strain on your budget.
