Calculate your full monthly mortgage payment including principal, interest, property tax, homeowners insurance, PMI, HOA fees, and tax deduction benefits.
Your actual monthly mortgage payment is much more than just principal and interest. The full PITI payment includes Property Tax, Insurance, and potentially PMI (Private Mortgage Insurance) and HOA fees. These additional costs can add 30-50% on top of the base P&I payment, and many first-time homebuyers are surprised by the difference.
Understanding the true cost of homeownership also requires factoring in the mortgage interest tax deduction. For homeowners who itemize, the ability to deduct mortgage interest and property taxes can reduce the effective monthly cost significantly — though the 2017 tax reform raised the standard deduction high enough that many homeowners now benefit more from the standard deduction.
This comprehensive PITI calculator models every component of your monthly housing payment, computes the mortgage interest tax deduction benefit, calculates your DTI (debt-to-income) ratio for qualification purposes, and provides an amortization schedule showing how your equity builds over time. Check the example with realistic values before reporting.
The true cost of a mortgage includes far more than P&I. This calculator reveals your complete monthly obligation including taxes, insurance, and PMI, plus shows the tax deduction impact and DTI ratio that lenders use for qualification. Keep these notes focused on your operational context. Tie the context to the calculator’s intended domain. Use this clarification to avoid ambiguous interpretation.
Monthly P&I = L × [r(1+r)^n] / [(1+r)^n − 1] where L = loan amount, r = monthly rate, n = total months Monthly Property Tax = Home Price × Tax Rate / 12 Monthly PMI = Loan × PMI Rate / 12 (if LTV > 80%) Total PITI = P&I + Property Tax + Insurance + PMI + HOA
Result: $2,916/month total PITI
On a $320K loan at 6.75%: P&I = $2,076 + property tax $417/mo + insurance $175/mo + no PMI (20% down) = $2,668/month. With $100K income filing MFJ, itemizing saves ~$3,500/year in taxes.

PITI stands for Principal, Interest, Taxes, and Insurance — the four components of a typical monthly mortgage payment. Lenders use PITI to calculate your DTI ratio for qualification.
Private Mortgage Insurance is required when your down payment is less than 20% (LTV > 80%). It typically costs 0.3-1.5% of the loan annually and can be removed once LTV reaches 78-80%.
Yes, up to $750,000 of mortgage debt ($375K if married filing separately). However, you must itemize deductions — if your standard deduction is higher, the mortgage interest deduction provides no additional benefit.
Most conventional loans require a DTI under 43%, though some programs accept up to 50%. FHA loans allow up to 57% in some cases. Lower DTI gives you better rates and more choices.
If you have an escrow account (required for most loans with < 20% down), yes — your lender collects property tax monthly and pays it when due. Otherwise you pay taxes separately.
Budget 1-3% of home value annually for maintenance and repairs. So a $400K home needs $4,000-12,000/year in maintenance plus any utility differences from your previous housing.
