Amortization and Balances
Compare loan amortization, fully amortizing payments, and negative amortization through their effects on principal balances.
Compare when debt payments are due, how they are allocated, and whether principal declines, remains outstanding, or increases.
Repayment, amortization, and balance describe related but different loan mechanics. Repayment identifies what the borrower must pay and when. Amortization explains how payments affect principal over time. The balance is the amount outstanding after payments, interest, advances, fees, and other permitted adjustments.
A borrower can make a payment without reducing principal. An interest-only payment keeps principal level, while a payment below accrued interest can increase the balance through negative amortization.
| Area | Primary question |
|---|---|
| Amortization Methods and Loan Balances | How is each payment allocated between interest and principal, and what balance remains? |
| Repayment Schedules and Terms | When are payments due, and how do grace periods, deferments, rollovers, and satisfaction change obligations? |
| Rule of 78 and Readjustment | How is precomputed interest allocated or rebated when a covered loan is paid before schedule? |
| Payment behavior | Interest covered? | Principal result |
|---|---|---|
| Fully amortizing | Yes | Declines to zero by maturity under stated assumptions |
| Partially amortizing | Yes | Declines but leaves a balloon balance |
| Interest-only | Yes | Remains level during the interest-only period |
| Negative amortization | No | Increases by capitalized unpaid interest |
| Extra principal | Yes, subject to allocation order | Declines faster if correctly applied |
Use the note, payment schedule, disclosures, and servicing history to identify:
Do not infer the balance from the number of payments alone. Variable rates, missed payments, fees, advances, modifications, and capitalization can move the actual balance away from the original schedule.

Compare loan amortization, fully amortizing payments, and negative amortization through their effects on principal balances.
Repayment schedules define payment timing, temporary relief, maturity, rollover, payoff, and final satisfaction of debt.
