Question 1

What does PITI stand for in mortgage lending?

Accepted Answer

PITI stands for Principal, Interest, Taxes, and Insurance—the four core components that make up a complete monthly mortgage payment.

Question 2

Why is PITI more accurate than a basic mortgage calculator?

Accepted Answer

Basic calculators show only principal and interest (P&I). PITI adds mandatory property taxes, homeowners insurance, private mortgage insurance (PMI), and HOA dues, which often add 30% to 50% to your actual monthly bill.

Question 3

When is Private Mortgage Insurance (PMI) required?

Accepted Answer

PMI is required on conventional loans when your down payment is less than 20% (LTV > 80%). It protects the lender and typically costs 0.3% to 1.2% of the loan amount annually.

Question 4

Can you provide a worked calculation for a $400,000 home?

Accepted Answer

On a $400,000 home with 10% down ($360,000 loan) at 6.5% APR for 30 years: Principal & Interest is $2,275.44/mo, property tax is $400.00/mo ($4,800/yr), homeowners insurance is $125.00/mo ($1,500/yr), and PMI is $150.00/mo. Total PITI is $2,950.44/month.

Question 5

How does an escrow account handle taxes and insurance?

Accepted Answer

Your mortgage servicer collects 1/12th of your estimated property taxes and insurance each month as part of your PITI payment, holding it in an escrow account to pay municipal tax and insurance bills on your behalf.

Question 6

Is my property financial data private on ToolboxDock?

Accepted Answer

Yes. All PITI calculations execute 100% locally in your web browser memory with zero tracking.

Question 7

When can I remove PMI from my monthly PITI payment?

Accepted Answer

Under the Homeowners Protection Act, you can request PMI cancellation when your loan balance reaches 80% of original home value, and lenders must automatically cancel it at 78% LTV.
