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.
Enter the loan amount you’re considering.
Enter the property value or purchase price.
The tool divides the loan by the value to estimate LTV.
It also shows the down payment — value minus loan — in dollars and as a percentage.
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.
LTV = loan balance ÷ property value
Use the output as a documented scenario result, not a guarantee.
Read the number in context
Worked scenario
Scenario: $240,000 ÷ $300,000 = 80% LTV.
Edge case
Edge case: same loan on $280,000 value is 85.7% LTV.
It does not determine approval, appraisal, or mortgage insurance requirements.
Before you act
• Use a supportable value source.
• Confirm lender calculation.
• Test a lower-value scenario.
Worked formula
LTV = loan balance ÷ property value
Is this a forecast?
No. It calculates the assumptions you enter.
Can it replace professional review?
No. Use current records and qualified advice.
What should I save?
Keep the assumptions and source records used for the decision.
