Loan to Value (LTV) Calculator
Calculate your loan-to-value ratio, combined LTV with a second lien, your equity percentage and how far you are from the 80% mark where PMI usually drops.
LTV 80.00% — 80% or below
At or under 80% LTV you normally avoid private mortgage insurance and qualify for a lender's better pricing tiers.
Distance to the 80% threshold
- Room before you hit 80% LTV
- $0.00
- Total debt secured on the property
- $320,000.00
Lenders use the lower of the appraised value and the purchase price, and PMI removal rules differ between loan types and countries. Estimates only, not financial advice.

About the Loan to Value (LTV) Calculator
The ByteTools Loan to Value Calculator divides your loan balance by the property's value to give the ratio lenders use to price risk. Enter the appraised value and your first mortgage balance, add a second lien or HELOC if you have one, and it returns LTV, combined LTV (CLTV), your equity in both percent and currency, and the gap to the 80% threshold.
That 80% line matters because it is where private mortgage insurance is normally cancellable on a conventional loan, and where rate pricing tiers usually improve. The tool tells you how much principal you would need to pay down, or how much the property would need to appreciate, to cross it.
For a purchase, lenders base LTV on the lower of the purchase price and the appraised value, so enter whichever of the two is smaller to match how your lender will see it. Everything is calculated locally in your browser and nothing is uploaded. Estimates only, not financial advice.
Frequently asked questions
How do you calculate loan to value?
Divide the loan amount by the property value and multiply by 100. A $240,000 mortgage on a $300,000 home is 240,000 ÷ 300,000 = 80% LTV. The remaining 20% is your equity.
What is the difference between LTV and CLTV?
LTV counts only the first mortgage. Combined LTV adds every lien secured on the property — second mortgages, home equity loans and HELOC balances. Lenders assessing a new second lien care about CLTV, which is usually the higher number.
What LTV do I need to avoid PMI?
80% or below on a conventional loan, which means a 20% down payment. If you start higher, PMI can normally be cancelled once the balance reaches 80% of the original value, and it drops automatically at 78% under US federal rules.
Is a lower LTV always better?
For borrowing costs, yes — lower LTV means less lender risk, better rate tiers and no mortgage insurance. The trade-off is that money tied up in home equity is not liquid, so it is a balance rather than a target to maximise.
Which value do lenders use, the price or the appraisal?
The lower of the two on a purchase. If a home appraises at $290,000 but you agreed $300,000, the lender bases LTV on $290,000 — which is why a low appraisal can force a bigger down payment.
