About LoanPayCal

A free, privacy-first mortgage calculator built for American homebuyers.

Why we built this

Most mortgage calculators on the internet are lead-generation tools. They look helpful, but behind the scenes they're collecting your data, showing you ads for mortgage brokers, and trying to sell you loan quotes.

We built LoanPayCal to be the opposite: a clean, accurate, privacy-first mortgage calculator that gives you the full picture — including property tax, home insurance, PMI, and HOA fees — without ads and without trying to sell you anything.

What makes us different

• No ads. Zero display ads, zero pop-ups.
• Complete PITI calculation. Most calculators only show principal & interest. We include property tax, insurance, PMI, and HOA — the way lenders actually calculate your monthly payment.
• Amortization schedule. See exactly how each payment splits between principal and interest, yearly or monthly.
• Extra payment calculator. Find out how much interest you can save by paying a little extra each month.
• 15 vs 30 year comparison. See the dramatic difference in total interest paid.
• Affordability calculator. Enter your income and debts to find your maximum affordable home price.

Our methodology

All calculations use standard US mortgage formulas:

• Monthly PI: Calculated using the standard amortization formula: M = P × [r(1+r)^n] / [(1+r)^n − 1]
• PMI rates: Estimated using industry-standard ranges: 0.25%–1.00% of loan amount annually, based on down payment percentage.
• Property tax: Based on the selected state's average effective tax rate. You can also enter a custom rate.
• DTI limits: Affordability calculations use the 28/36 rule (housing costs ≤ 28% of gross income; total debt ≤ 36%).
