Loan Payment Calculator
The Loan Payment Calculator estimates monthly installments using the standard amortization formula with principal, annual rate, and term. It helps compare financing options before signing a contract, test affordability under different rates, and understand payment sensitivity over time. Use it as a mathematical baseline, then add taxes, insurance, and fees to model real monthly cost.

Worked example: amortized payment planning
Loan amount is 180,000, annual interest 5.2%, term 20 years. The calculator estimates the monthly payment from the standard amortization formula, allowing budget stress tests.
Interpretation notes
Do not treat the payment estimate as the full cost of borrowing. Include insurance, fees, and taxes externally to get the real monthly burden.
