The short answer
Last updated: July 2026
Loan-to-value (LTV) is the loan amount divided by the property value, shown as a percentage. It tells a lender how much equity cushions the loan. A $240,000 loan on a $300,000 property is 80% LTV, leaving a $60,000 (20%) down payment. Lenders cap LTV by program and property type. This estimate uses your inputs.

20.0% of value — the equity between the loan and the price.
Estimate based on your inputs. Not a promise of results.
Estimate only. Lenders set their own maximum LTV by loan program and property type, and mortgage insurance often applies above a certain threshold. This is arithmetic on your numbers, not a lending decision.

How it works
How this tool works.
Loan-to-value is one of the first numbers a lender looks at. It measures the loan against the property’s value, so a lower LTV means more of your own equity is at stake and less risk for the lender. It also drives whether mortgage insurance applies and, often, the rate you’re offered.
Enter the loan amount and the property value, and this calculator estimates LTV along with the down payment it implies in dollars and percent. It’s arithmetic on your inputs, not a lending decision.

Make the result useful
Loan-to-value context
Loan balance is the principal used in the ratio.
Property value can be purchase price, appraisal, or another stated value basis.
LTV changes when either balance or value changes.
A lender may use a different value, program limit, or adjustment.
The assumptions that move this result
Loan balance
Current or proposed principal.
Property value
Stated appraisal, purchase, or market-value basis.
Value date
When that value applies.
Loan type
Program context that may set a limit.
Calculation lens
LTV = loan balance ÷ property value

Worked scenario
Scenario: $240,000 ÷ $300,000 = 80% LTV.
Edge case
Edge case: same loan on $280,000 value is 85.7% LTV.

Answers
Questions, answered plainly.
What LTV do lenders allow?
It varies by loan program and property type, and investment properties usually require a lower LTV than a primary home. Above a certain threshold, mortgage insurance often applies. Each lender sets its own maximum.
How does LTV relate to the down payment?
They’re complements. On a purchase, LTV plus your down-payment percentage add to 100%. An 80% LTV means a 20% down payment; a larger down payment lowers the LTV.
Which value do lenders use?
Typically the lower of the purchase price or the appraised value. If an appraisal comes in under the contract price, the lender sizes the loan off the appraisal, which can raise the effective LTV.
