What this calculator does

LTV compares a mortgage with the property’s value. It affects interest rates, mortgage insurance and whether you qualify for refinancing.

Formula and method

LTV = first mortgage ÷ value; CLTV = (first + second loans) ÷ value

Worked example

Calculated by this tool with its default inputs:

Inputs

  • First mortgage amount: 320000 (any currency)
  • Second loan / HELOC (optional): 40000 (any currency)
  • Appraised value or price (whichever is lower): 400000 (any currency)

Results

  • LTV: 80%
  • Combined LTV (CLTV): 90%
  • Paydown needed to reach 80 % LTV: 0

How to read the results

At or below 80 % LTV, many conventional loans no longer require mortgage insurance.

Assumptions and limitations

  • Lenders use the lower of purchase price and appraised value when buying.

Financial results are estimates based on the inputs and assumptions shown. They are not financial advice; confirm figures with your lender, provider or a qualified adviser before making decisions.

Questions

Does LTV change over time?

Yes — it falls as you repay principal and as the home’s value rises.
