Loan Calculator
A loan calculator is an essential tool for mortgage and auto loan decisions. Supports two repayment methods: <strong>Equal Interest</strong> (fixed monthly payment, higher initial interest portion) and <strong>Equal Principal</strong> (fixed principal repayment per month, decreasing interest — lower total interest). Enter loan amount, annual rate, and term to see monthly payments and total interest.
Quick presets for common scenarios (mortgage $1M 30yr 3.85%, auto loan $150K 5yr 4.75%). Expand the amortization schedule for month-by-month details — principal, interest, and remaining balance. All calculations are client-side; input data is never stored or uploaded. Note: results are for reference only; actual loan terms are governed by financial institution contracts.
