How Our Loan Comparison Tool Works

Our loan comparison tool calculates and compares key metrics for multiple loan options side-by-side. The calculation uses standard amortization formulas to determine monthly payments, total costs, and interest amounts, helping borrowers make informed financing decisions.

The Loan Payment Formula

Monthly Payment = P × [r(1 + r)^n] / [(1 + r)^n - 1]
Where: P = Principal, r = monthly rate, n = number of payments
Total Cost = Monthly Payment × Number of Payments
Total Interest = Total Cost - Principal

The calculator computes monthly payment using the amortization formula, then calculates total cost by multiplying by the number of payments. It identifies the loan with lower total cost and shows potential savings. This helps borrowers understand not just monthly affordability but long-term financial impact.

Mathematical Foundation

Loan comparison is based on amortization mathematics from financial theory. The amortization formula calculates equal periodic payments that fully repay principal and interest over the loan term. Each payment includes both interest (on remaining balance) and principal reduction. Early payments are mostly interest; later payments are mostly principal. Comparing total cost reveals true long-term expense differences between loan options.

  • Lower interest rates significantly reduce total cost over time
  • Shorter loan terms have higher monthly payments but lower total interest
  • Monthly payment impacts cash flow; total cost impacts wealth
  • Small rate differences compound into large savings over decades
  • Consider both payment affordability and total cost in decisions
  • Factor in fees, closing costs, and prepayment options
