Frequently Asked Questions
What is PITI?▼
PITI stands for Principal, Interest, Taxes, and Insurance — the core components of a monthly mortgage payment. HOA and PMI may be added separately.
How does an extra payment affect my loan?▼
Extra payments go directly toward principal, reducing total interest and shortening the loan term. Our schedule shows the updated payoff timeline.
What is LTV?▼
Loan-to-Value ratio = Loan Amount ÷ Home Price. Above 80% LTV typically requires PMI until you reach 78% through payments or appreciation.
Does this include closing costs?▼
No. Closing costs (origination, title, appraisal) are separate one-time fees at purchase.
How accurate is the amortization schedule?▼
The schedule uses standard fixed-rate amortization. Actual payments may vary slightly due to lender rounding.
Can I compare 15 vs 30 year terms?▼
Yes — change the loan term and recalculate to compare monthly payment vs total interest.
What interest rate should I use?▼
Use your locked rate if available, or current market rates from your lender for estimates.
Is property tax monthly or annual?▼
Enter your monthly escrow amount. Divide annual tax by 12 if needed.
When can I remove PMI?▼
Typically when LTV reaches 78% through scheduled payments, or 80% if you request removal.
Is my data private?▼
Yes. All calculations happen locally in your browser — nothing is sent to a server.
