Formulas Used

  • Loan Payment (EMI):
  • EMI = [r × (1 + r)^n] / [(1 + r)^n − 1]
  • Debt-to-Income (DTI):
  • Max Housing = Income × DTI − Expenses
  • Loan Amount:
  • Loan = Payment / Loan Factor
  • Home Price:
  • Price = Loan + Down Payment
  • Future Value:
  • FV = P × (1 + appreciation)^t
  • Inflation Adjustment:
  • Real Value = FV / (1 + inflation)^t
