How to use the LTV Calculator

  1. Choose whether the loan is for a purchase or a refinance, and enter the price and the appraised value.
  2. Enter the first mortgage amount and any other loans secured on the home, including a HELOC if you have one.
  3. Read the LTV, the combined LTV and, with a HELOC limit, the HCLTV.

The ratios

value = lower of purchase price and appraised value   (purchase)value = appraised value                                (refinance)LTV   = first mortgage ÷ valueCLTV  = (first mortgage + other loans + HELOC drawn) ÷ valueHCLTV = (first mortgage + other loans + HELOC credit limit) ÷ value

These follow the definitions in the Fannie Mae Selling Guide, sections B2-1.2-01 to B2-1.2-03. Other lenders and investors publish their own, which are often the same but need not be.

Rounding

The exact ratio is shown to two decimal places of a percent. The Selling Guide’s rounded LTV first cuts the ratio to two decimal places, without rounding, and then rounds up to the next whole percent. Only an exact whole percent stays where it is.

The home equity calculator starts from a home you already own and works out equity and the balance that would reach a target LTV. The down payment calculator works out the deposit and loan for a purchase price.

With your numbers

  1. Value used = $400,000.00
  2. CLTV = ($320,000.00 + $0.00 + $0.00) ÷ $400,000.00 = 80%
  3. LTV = $320,000.00 ÷ $400,000.00 = 80%

Quick reference

Ratios only, on the value you enter. Lenders set their own limits and may value the home differently.

Common questions about the LTV Calculator

Which value does LTV use when the appraisal and the price differ?
On a purchase, Fannie Mae’s Selling Guide uses the lower of the two. If you agree to pay 400,000 and the appraisal comes in at 390,000, a 320,000 loan is 82.05% of value, not 80%. On a refinance there is no price, so the appraised value is used.
What is the difference between LTV, CLTV and HCLTV?
LTV counts the first mortgage only. CLTV adds every other loan secured on the home, with a HELOC counted at the amount drawn. HCLTV is the same as CLTV but counts the HELOC’s full credit limit, drawn or not, because it could be drawn at any time.
Why is the rounded LTV different?
The Selling Guide truncates the ratio to two decimals of a percent and then rounds up to a whole percent, so 80.001% becomes 80% but 94.01% becomes 95%. The rounded figure is what a lender following that guide compares with its limits. The page shows it alongside the exact ratio.
What LTV do I need?
That depends on the lender, the loan programme and the property, and it changes. This page does not state a limit. Ask the lender for theirs and compare it with the ratio here.
