Principal Payment

A principal payment is the portion of a loan payment that reduces the outstanding balance owed on the note rather than paying interest, building the borrower's equity as amortization schedules allocate more dollars to principal over time.

Exam context

Principal payment reduces loan balance. Interest payment compensates lender. Early payments mostly interest on amortized loan. PITI includes principal, interest, taxes, insurance.

Amortization mechanics

Early in a fixed-rate loan, most of each payment covers interest because interest accrues on the larger balance. Later payments shift toward principal. Extra principal payments shorten the term and reduce total interest but do not change the contractual monthly amount unless the loan recasts.

Equity and disclosures

Borrowers review amortization schedules at closing. Sellers applying net proceeds must satisfy remaining principal plus accrued interest at payoff. Agents comparing rent versus buy should explain that principal payments increase ownership stake unlike rent, while interest is the cost of borrowing.

Examples

  • Month 120 allocation

    On a 30-year loan, payment number 120 might apply $612 to principal and $1,088 to interest, reversing the ratio from year one when interest dominated.

  • Extra principal lump sum

    A borrower sends an additional $5,000 principal payment, dropping the balance immediately and shortening payoff by several months without refinancing.
