Loan to Value Calculator

This tool works out the loan to value ratio in the three forms underwriting uses: LTV on the first mortgage alone, CLTV with every other lien added, and HCLTV with the undrawn part of a home equity line counted at its full limit. You enter the property value and the balances owed, and it returns each ratio, the equity behind them and where the first mortgage sits against the 80% line. A second option takes a balance and a target ratio and returns the principal reduction or the appraised value that would reach it. The distinction between the three ratios is what decides a second mortgage or a credit line application, since an open line counts against you whether or not anything has been drawn on it.

Calculator Type

Enter what is owed against the property. A second lien or an open credit line changes the ratio a lender looks at.

Property Value ($) *

The appraised value. On a purchase a lender uses the lower of the price and the appraisal.

First Mortgage Balance ($) *

What is owed now, not what was borrowed.

Other Liens Owed ($)

A second mortgage, and the part of a home equity line already drawn.

Undrawn Credit Line Still Available ($)

The part of a home equity line not yet drawn. Underwriting counts the whole line in the HCLTV.
