See How Making Extra Payments Can Shorten Your Loan and Save Interest
How Loan Calculations Are Done
Monthly Payment Calculation
Your monthly payment is determined using a standard loan formula that considers the loan amount, interest rate, and repayment period.
- M = Monthly payment
- P = Loan amount (principal)
- r = Monthly interest rate (APR divided by 12)
- n = Total number of payments
How Interest Is Calculated
Each time you make a payment:
- Interest is calculated on the remaining balance
- A portion of your payment covers interest
- The rest reduces the principal
- Your balance decreases accordingly
Impact of Extra Payments
Paying more than the required amount directly reduces your principal. This helps:
- Lower total interest paid
- Shorten your loan term
- Build faster progress toward payoff
Lump-Sum Payment Effect
A one-time large payment significantly reduces your remaining balance, which:
- Cuts future interest costs
- Speeds up loan repayment
