Pro Tips

  • Try adjusting the loan term or making extra payments to see dramatic interest savings-even small additional payments can cut years off your loan.
  • Use the comparison feature to evaluate different interest rates and terms; sometimes a shorter term saves more than you'd expect.
  • Keep your amortization schedule handy for tax purposes if applicable, as some loan interest may be deductible.
  • Compare the calculator results with official loan offers to ensure accuracy and catch any hidden fees or terms.
