About Mortgage Calculations

Mortgage calculations involve determining how much you'll pay each month for your home loan. The payment typically includes principal and interest, and may also include property taxes, insurance, and private mortgage insurance (PMI).

Key Terms
  • Principal: The original loan amount.
  • Interest: The cost of borrowing money, expressed as a percentage.
  • Term: The length of time to repay the loan (typically 15 or 30 years).
  • Amortization: The process of paying off debt with regular payments of principal and interest.
  • PMI: Private Mortgage Insurance, required when down payment is less than 20%.
Tips for Mortgage Planning
  • Making extra payments can significantly reduce your loan term and save on interest.
  • A shorter loan term means higher monthly payments but lower total interest paid.
  • Consider refinancing if interest rates drop substantially below your current rate.
  • Aim for a down payment of at least 20% to avoid PMI costs.
  • Factor in property taxes, insurance, and possible HOA fees when budgeting for your mortgage.
