The four parts of PITI
Most mortgage payments are built from the same four pieces. Knowing what each one does makes your Loan Estimate and monthly statement much easier to read.
- Principal: the part that pays down what you borrowed.
- Interest: what the lender charges you to borrow.
- Taxes: your property taxes, usually collected monthly and paid from an escrow account.
- Insurance: your homeowners insurance premium, also usually paid from escrow.
How principal and interest work over time
On a fixed-rate loan, your principal and interest payment stays the same for the life of the loan. What changes is the mix. Early on, most of each payment goes to interest. Over time, more of it goes to principal.
On an adjustable-rate loan, principal and interest can change when the rate adjusts. Your loan documents explain when and by how much.
Where the taxes come from
Your local taxing authority sets your home's assessed value and the tax rate. Tax bills can rise after a reassessment or a rate change. Some areas offer exemptions for primary homes, seniors or veterans. Rules vary by state and locality, so check with your county or city, or ask your settlement agent.
Homeowners insurance
Your lender requires homeowners insurance on the home. The premium depends on things like rebuild cost, location, the age of your roof and your claims history. It can change at each renewal. If your home is in a flood zone, flood insurance may be required too.
What escrow does
Most loans have an escrow account. Each month, part of your payment goes into it. Your servicer then pays your tax and insurance bills when they're due.
Once a year, your servicer reviews the account. If taxes or insurance went up, your payment may rise, and you may owe a shortage. If they went down, your payment may drop, and you may get a refund of any surplus.
A sample monthly payment
Here is how the pieces add up on a $320,000 loan. Hypothetical example. APR may differ; example only. Rates change daily.
- Principal and interest: about $2,076 (30-year fixed at 6.75%)
- Property taxes: about $333 (on a $4,000 yearly bill)
- Homeowners insurance: about $125
- PITI: about $2,534
- Add PMI or HOA dues, if any, for the full housing payment
Example details: $320,000 30-year fixed at 6.750% (6.778% APR): 360 monthly payments of $2,075.51. Principal and interest only; taxes and insurance not included, so the actual payment will be higher. Unless noted, APR assumes ZERO Closing Costs, no discount points and 15 days of prepaid interest. Hypothetical example prepared November 4, 2026, not a current CapCenter rate offer; subject to credit approval.
Why PITI matters for approval
When lenders measure debt-to-income, they use your full housing payment: PITI plus any mortgage insurance and HOA dues. Two homes at the same price can have very different PITI if taxes or insurance differ. That can change how much you're able to borrow.
Ways to lower your PITI
Some of these trade one cost for another, so compare the full picture before you decide.
- Shop your homeowners insurance before closing and at renewal.
- Ask about a tax assessment appeal if your assessment looks high.
- Put more down to lower your loan amount or avoid PMI.
- Look at homes with lower taxes, insurance or HOA dues.
