Formulas Used

  • Monthly Mortgage Payment:
  • M = P × [r(1+r)^n] / [(1+r)^n − 1]
  • Interest per Month:
  • Interest = Remaining Balance × Monthly Rate
  • Principal Payment:
  • Principal = EMI − Interest
  • Total Interest:
  • Total Interest = Total Payments − Loan Amount
  • Total Cost:
  • Total Cost = Loan + Interest + Taxes + Insurance + HOA
  • Debt-to-Income (DTI):
  • DTI = (Monthly Payment / Monthly Income) × 100
