Loan Details

Bi-weekly pays off faster and saves interest

📊 Loan Formula:

M = P × [r(1+r)^n] / [(1+r)^n - 1]
Where:
• M = Monthly payment
• P = Principal (loan amount)
• r = Monthly interest rate
• n = Number of payments

💡 Tips:

  • • Lower interest rates save thousands over time
  • • 20%+ down payment avoids PMI
  • • Property tax & insurance vary by location
  • • Extra principal payments reduce total interest
