The LTV Calculator determines your loan-to-value ratio by dividing loan amount by property value, then shows required down payment and whether PMI applies at your target loan level. Input purchase price and loan amount to see your LTV percentage and understand lender requirements.
LTV is the lender's primary risk metric — higher LTV means more risk and higher insurance/rate costs. By understanding your LTV and the 80% threshold where PMI drops, you make informed decisions about reaching 20% down payment or paying PMI to buy sooner.
Who it's for
- Buyers deciding between down payment amounts and PMI cost trade-offs at various LTV levels
- Lenders calculating PMI requirements and risk-adjusted rates based on LTV positions
- Real estate investors understanding refinancing capacity based on property value and LTV
- Appraisers and underwriters assessing risk and eligibility based on LTV calculations
How it works
Enter purchase price and down payment (or loan amount)
LTV = Loan ÷ Value. If you know one, calculate the other.
Review LTV result
Under 80% = no PMI (conventional); 80–90% = PMI likely; 90%+ = high risk.
Project LTV improvement
As you pay down principal and property appreciates, LTV improves.
Why it matters
Instantly calculate LTV ratio from purchase price and loan amount
Determine required down payment for target LTV
Identify PMI applicability and removal timeline
Model when you'll reach 80% LTV (PMI removal) and 70% LTV (refi threshold)

Frequently asked questions
What LTV triggers PMI?
Over 80% LTV typically triggers PMI on conventional loans. FHA and VA have different rules (FHA: 96.5% LTV; VA: no PMI).
What's a good LTV to target?
70–75% LTV is strong; 80% is acceptable; 85%+ is high-risk. Lower LTV = lower PMI cost or avoidance.
How fast does LTV improve?
Combination of principal paydown (5–10% yearly on 30-year) and property appreciation (2–4% annually). Total: 7–14% annual LTV improvement typical.
Can I reduce LTV via appraisal?
If property appreciated significantly, new appraisal shows higher value = lower LTV = PMI removal. Request appraisal if you think value jumped.
