How is my monthly payment calculated?

Your monthly payment is calculated using the standard amortization formula. The formula takes into account three key factors: the principal amount (how much you borrow), the annual interest rate (APR), and the loan term (how many months you have to repay).

M = P [r(1+r)^n] / [(1+r)^n - 1]

Where M = monthly payment, P = principal, r = monthly interest rate, n = number of payments.

Tips to lower your monthly payment

  • Improve your credit score before applying — even 20 points can make a difference
  • Choose a longer repayment term (note: you'll pay more in total interest)
  • Compare offers from multiple lenders to find the lowest APR
  • Consider a co-signer or secured loan option for a lower rate
  • Look for lenders with no origination fees to reduce upfront costs
