Formulas Used

  • Monthly Payment (EMI):
  • M = P × [r(1+r)^n] / [(1+r)^n − 1]
  • Monthly Interest:
  • Interest = Remaining Balance × Monthly Rate
  • Principal Payment:
  • Principal = EMI − Interest
  • Remaining Balance:
  • Balance = Previous Balance − Principal − Extra Payments
  • Total Interest:
  • Total Interest = Sum of all monthly interest
  • Affordability:
  • Affordable Payment = (Income × DTI) / 12
