What Are the Four Components of PITI?
Principal is the portion that reduces your loan balance. Interest is the cost of borrowing, determined by your rate and remaining balance. Taxes are property taxes collected monthly by your lender and held in escrow. Insurance includes homeowners insurance and, if applicable, [private mortgage insurance (PMI)](/glossary/private-mortgage-insurance). Together, these define your true monthly housing cost.
How Do Lenders Use PITI?
Lenders calculate your front-end ratio by dividing your PITI by gross monthly income. Most conventional loans require this ratio to be 28% or less. FHA loans allow up to 31%. This ratio helps ensure you can comfortably afford your home. A $6,000 gross monthly income, for example, supports a PITI of up to $1,680 under the 28% guideline.
Why Does PITI Change Over Time?
Even with a fixed-rate mortgage, your PITI can change. Property taxes are reassessed periodically and often increase. Homeowners insurance premiums may rise. If your escrow analysis shows a shortfall, your lender will adjust the monthly escrow portion upward. Only the principal and interest portions stay constant on a fixed-rate loan.
Frequently asked questions
Is PITI the same as my mortgage payment?
PITI represents the total payment most homeowners make, but some costs like HOA fees are not included. If your lender does not escrow taxes and insurance, your mortgage payment may only cover principal and interest, and you pay taxes and insurance separately.
How can I lower my PITI payment?
You can lower PITI by making a larger down payment, buying mortgage points to reduce your rate, shopping for cheaper homeowners insurance, appealing your property tax assessment, or eliminating PMI once you reach 20% equity.
