How Student Loan Payoff Is Calculated
The simulation runs month by month for both scenarios:
Without Extra Payment:
- Each month, interest is calculated on the remaining balance.
- The monthly payment covers interest, and the rest reduces principal.
- The process continues until the balance reaches zero.
With Extra Payment:
- The same process, but the extra payment is applied directly to the principal each month.
- This accelerates the payoff and reduces total interest.
Interest Saved = Total Interest (Original) – Total Interest (With Extra)
