Total Loan to Value: Calculate Combined LTV

Total loan to value (total LTV, or TLTV) is the combined balance of loans secured by a property divided by the property’s value, expressed as a percentage. Enter the property value and the balances of the loans secured against it to calculate total LTV, the combined loan amount, and the equity remaining by this calculation.

Formula

Total LTV = (combined balances of loans secured by the property ÷ property value) × 100.

• Property value (val): the value used as the denominator, in dollars. It may be a purchase price, an appraisal, or another value specified for the calculation.
• First mortgage balance (pri): the current outstanding balance of the first mortgage, in dollars.
• Other secured loan balances (sec): the balances of any additional loans secured by the same property, in dollars. This may include a second mortgage or a home equity loan or line of credit.
• Total LTV (ltv): the combined secured balances as a percentage of property value.

The calculator adds the first mortgage and other included secured balances, then divides their sum by the property value. For example, if the combined balances equal the property value, total LTV is 100%. If the balances exceed that value, the result is above 100%. This calculation does not establish what a lender will count or how a property will be valued.

Worked Example

Using the calculator’s default inputs:

1. Property value: $300,000.
2. First mortgage balance: $210,000; other secured loan balances: $30,000.
3. Combined secured balances: $210,000 + $30,000 = $240,000.
4. Total LTV: ($240,000 ÷ $300,000) × 100 = 80.00%.
5. Property value less included balances: $300,000 − $240,000 = $60,000.

The $60,000 figure is a simple difference between the entered value and balances, not a guaranteed sale proceeds estimate or a complete measure of equity. Selling costs, other claims, and changes in value are not included.

Assumptions

• The property value and loan balances are entered in the same currency and refer to the same property.
• All amounts are entered as dollar values; the calculator uses the balances as supplied and does not accrue interest or update them over time.
• Any additional balance included is secured by the property. Unsecured debt is excluded.
• The calculation does not include fees, taxes, insurance, PMI, escrow, or transaction costs.

What Total LTV Measures

LTV is a ratio, not a loan payment or interest-rate calculation. A first-mortgage LTV considers only the first mortgage balance. Total LTV combines that balance with other loans secured by the same property. Some contexts use a related measure called combined loan to value (CLTV); terminology and the balances included can vary, so check the specific definition being used.

Consider a property valued at $400,000 with a $250,000 first mortgage and a $40,000 home equity loan. First-mortgage LTV alone is 62.5% ($250,000 ÷ $400,000). Total LTV is 72.5% (($250,000 + $40,000) ÷ $400,000). Looking only at the first mortgage would leave out $40,000 of property-secured debt and understate the combined ratio.

The ratio describes debt relative to a selected property value at a point in time. It does not tell you the monthly payment, the loan’s total cost, or whether an application will be approved. Those involve other figures and criteria that this calculator does not model.

Choosing Inputs and Reading the Result

Use balances rather than original loan amounts when the question is about current LTV. A loan may have been partly repaid, and its outstanding balance can differ from the amount borrowed at closing. For a proposed transaction, the relevant calculation may instead use the anticipated new loan amount and any other secured balances that will remain; confirm which figures are intended.

• Use a consistent property value: An estimate, purchase price, and formal appraisal can differ. The choice affects the percentage, so use the value specified for the purpose and record its date.
• Include the relevant secured debts: Add each balance that the particular calculation defines as secured by the property. Do not add credit cards or other unsecured debts merely because they belong to the property owner.
• Check shared or revolving balances: For a line of credit, use the balance or other amount required by the calculation’s definition. Different processes may treat available credit differently; this calculator uses only the amount entered.
• Interpret percentages carefully: A lower total LTV means the included balances are smaller relative to the entered value. It does not by itself establish a lender’s terms, costs, or decision.

For a rough sense of the arithmetic, total LTV below 100% means the included balances are less than the entered property value; 100% means they equal it; above 100% means they exceed it. This comparison is not a formal appraisal or proof of realizable equity. Property values can change, and the figure may be outdated if balances or values have moved.

Common Mistakes and Limits

A frequent mistake is dividing only the first mortgage by the property value while calling the result total LTV. Another is using the original mortgage principal instead of its current balance, or omitting a second loan secured by the property. These choices can materially change the result.

Keep the inputs in the same currency and enter full dollar amounts, not amounts in thousands. For instance, enter 300000 for $300,000, not 300. The calculator rounds displayed results to two decimal places; small rounding differences may occur when comparing them with a calculation based on rounded figures.

Also avoid treating the difference between value and debt as cash you could receive. A sale or refinancing calculation may involve costs and other amounts, and the property value itself may not match a future transaction price. The calculator is a snapshot using only the inputs supplied; it does not determine lender-specific definitions or current application requirements. Get any required loan balances, valuation, and calculation method from the relevant lender.

Frequently Asked Questions

How do you calculate total loan to value?
Add the balances of the loans secured by the property, divide by the property value, and multiply by 100. For example, $240,000 in combined balances on a $300,000 property gives 80% total LTV.

What is the difference between LTV and total LTV?
LTV often refers to one loan, commonly the first mortgage, divided by property value. Total LTV includes additional qualifying loans secured by that property. Definitions can vary by context.

Does total LTV include a home equity loan?
Include its outstanding balance when it is secured by the same property and the calculation’s definition calls for it. Confirm how a specific lender or document treats a home equity line of credit.

Can total LTV be over 100%?
Yes. It is above 100% when the included secured balances exceed the entered property value. The result is a ratio, not a guarantee about sale proceeds or a lender’s decision.

Should I use the purchase price or an appraisal?
Use the value specified for the calculation. Purchase price, an appraisal, and a current estimate may differ, and the appropriate figure depends on the context.

Is total LTV the same as equity?
No. Total LTV is a percentage ratio. Property value minus the included balances is a simple dollar difference, but it may omit costs, other claims, and changes in value.

This result is an estimate based on your inputs; the lender’s disclosure gives the exact figures.
