How the Calculation Works
The calculator uses a standard loan amortization formula to compute your monthly payments:
Monthly Payment Formula:
Monthly Payment =
P × r × (1 + r)^n ÷ ((1 + r)^n − 1)
Where:

- r = Monthly interest rate
- n = Number of payments (loan term)
Additionally, it adds sales tax and other fees to give a complete cost overview.
