Combined Loan-to-Value (CLTV) ratio – Meaning, formula, calculation & impact on loan eligibility

Combined Loan-to-Value (CLTV) ratio – Meaning, formula, calculation & impact on loan eligibility

The Combined Loan-to-Value (CLTV) ratio is a number lenders use to assess how much you are borrowing relative to the property’s value. It considers all loans secured by the same property, including the main mortgage and any additional loans, such as a home equity loan or line of credit.

When lenders compare the total loan amount with the property’s value, they can see how much of the property is financed. CLTV is important because it helps lenders calculate the lending risk. A higher CLTV means more risk for the lender. It can affect your loan approval chances. It can also change the amount of the loan you can get and the interest rate you may be offered.

Key highlights of the combined loan-to-value ratio

CLTV’s full form, combined loan-to-value, represents the total debt secured by a property compared to its current market value.  The basic CLTV formula is:

Total of all property loans/Property value × 100

Lenders use this ratio to check your eligibility and measure lending risk. A lower CLTV usually improves the chances of loan approval and may lead to better interest rates. Most lenders prefer a CLTV of 80% or lower, as it indicates you have more equity and lower default risk.

For instance, if a home is worth Rs. 50 lakh, with a Rs. 30 lakh mortgage and a Rs. 5 lakh home equity loan, the CLTV is 70% (Rs. 35 lakh/Rs. 50 lakh x 100).

What is the Combined Loan-to-Value (CLTV) ratio?

Imagine a house is worth Rs. 60 lakh, for which you have taken a main home loan of Rs. 35 lakh. Later, you take another Rs. 10 lakh loan using the same property. Lenders calculate a CLTV considering the entire Rs. 45 lakh.

CLTV helps lenders determine how much money you have borrowed against a property compared to the property’s total value. The CLTV ratio is different from the standard loan-to-value ratio, as the latter only considers the primary mortgage. CLTV gives lenders a clearer picture of the total debt tied to the property.

How to calculate the combined loan-to-value ratio?

The step-by-step process to calculate the CLTV ratio is as follows:

1. Identify all property-backed loans

List every loan secured by the property, such as the main home loan, second mortgage, or home equity loan.

2. Find the outstanding balance

Calculate the current outstanding balance. Make sure you do it for each of these loans.

3. Add the balances together

Combine the remaining amounts of all loans to get the total debt tied to the property.

4. Determine the current property value

Use the latest market value or property appraisal.

5. Apply the formula

CLTV = (Total loan balance / Current property value) × 100.

CLTV formula with explanation

The simple CLTV formula is:

CLTV = (Total Outstanding Loan Balances / Current Property Value) × 100

In this formula,

  • Total outstanding loan balances refer to the combined amount you still owe on all loans secured by the property, such as the main mortgage and any additional loans.
  • Current property value refers to the present market value or appraised value of the property.

The result is multiplied by 100 to convert it into a percentage. The CLTV formula makes it easier for lenders to assess borrowing risk.

Example calculation of the CLTV ratio

Suppose a home’s value is worth Rs. 80 lakh in the current market. The owner has a primary home loan of Rs. 45 lakh and later takes a second loan of Rs. 15 lakh using the same property.

To calculate CLTV, you will need to first add both loan balances:

Rs. 45 lakh + Rs. 15 lakh = Rs. 60 lakh

Next, you will divide the total loan amount by the property value:

Rs. 60 lakh / Rs. 80 lakh = 0.75

Finally, multiply this by 100 to get the percentage.

The CLTV ratio in this example is 75%, showing that 75% of the property’s value is financed through loans.

Loans included in the CLTV ratio calculation

The combined loan-to-value ratio includes all loans secured by the same property. Lenders consider these loans to understand the total debt linked to the property.

  • Primary home loan: The main mortgage used to purchase the property.
  • Top-up loan: An extra loan taken from the same lender on an existing home loan.
  • Second mortgage: Another loan taken from a different lender using the same property as security.
  • Home equity loan: A loan borrowed against the equity built in the property.
  • Home Equity Line of Credit (HELOC): A flexible credit line secured by the property.

Lenders measure the full borrowing risk after including all these loans.

CLTV vs LTV – Understanding the key differences

Both LTV and CLTV ratios help lenders understand how much of a property’s value is financed through loans. However, they differ in what loans they include and how they measure borrowing risk.

How does the CLTV ratio affect loan approval and interest rates?

The combined loan-to-value ratio plays an important role in loan approval and interest rates. It helps lenders understand how much total debt is tied to a property. A higher CLTV means the borrower has taken more loans compared to the property’s value, which increases the lender’s risk. As a result, lenders may become stricter when reviewing the loan application.

Borrowers with a high CLTV may face higher interest rates, smaller loan amounts, or even rejection in some cases. However, a strong credit score, stable income, and good repayment history can improve approval chances. A lower CLTV usually leads to better loan terms and lower interest rates.

What is considered a good CLTV ratio?

A good CLTV ratio usually means the borrower has a healthy amount of equity in the property. Generally, lenders prefer a CLTV of 80% or lower, as it indicates lower risk. Some lenders may allow a CLTV between 80% and 90%, but this may come with stricter approval rules or higher interest rates.

If the CLTV goes above 90%, the loan may be considered riskier and harder to approve. The acceptable CLTV can vary depending on the lender, loan type, borrower’s credit score, and income stability. Borrowers with strong financial profiles may still qualify even with a slightly higher CLTV.

Regulatory guidelines and LTV caps for housing loans

The Reserve Bank of India (RBI) sets regulatory rules for housing loans in India. These rules place loan-to-value caps to limit how much banks can lend compared to the property value. For example, lenders may finance up to 90% of the property value for loans up to Rs. 30 lakh, up to 80% for loans between Rs. 30 to Rs. 75 lakh, and about 75% for loans above Rs. 75 lakh.

These limits ensure borrowers contribute a down payment and reduce lending risk. Since CLTV includes all loans on the property, these LTV caps indirectly influence how much additional borrowing lenders allow.

Important factors to consider before opting for multiple loans on a property

You must consider the following key factors before securing multiple loans on a property:

  • Repayment capacity: Make sure your monthly income can comfortably cover multiple EMIs without affecting daily expenses.
  • Property value changes: Property prices may rise or fall, which can affect your equity and overall loan risk.
  • Total interest burden: Taking more than one loan increases the overall interest you pay over time. You must be mindful of the same.
  • Loan tenure and EMI structure: Check how long the repayment period will be and whether the EMIs are manageable.
  • Impact on CLTV ratio: Multiple loans raise the CLTV, which may limit future borrowing options.
  • Long-term financial planning: Consider your future goals, savings, and emergency funds before taking on additional debt.

How to improve or maintain a healthy CLTV ratio?

You can improve or maintain a healthy CLTV ratio with the tips mentioned below:

  • Make regular prepayments: Paying extra toward your loan principal reduces the total outstanding balance over time.
  • Avoid unnecessary borrowing: Limit taking additional loans against the same property unless truly needed.
  • Increase your down payment: A larger initial payment lowers the loan amount and improves the ratio.
  • Track property value: Improvements or market appreciation can increase the property’s value and reduce CLTV.
  • Choose a shorter loan tenure if possible: Faster repayment lowers the outstanding balance sooner.
  • Maintain strong finances: Stable income and disciplined repayments help manage debt levels and keep your CLTV ratio at a healthy level.

Tax and financial planning considerations linked to CLTV

When you take multiple loans on a property, it can affect both tax benefits and overall financial planning. In some cases, you may claim tax deductions on home loan interest and principal repayments, depending on how the loan is used. However, when several loans are linked to the same property, it becomes important to keep clear records and understand which payments qualify for tax benefits.

A higher CLTV also means more total debt, which increases long-term financial commitments. You should review your repayment capacity, savings goals, and future expenses before adding new loans. Careful planning helps balance tax advantages with manageable debt levels.

FAQs

What is the Combined Loan-to-Value (CLTV) ratio?

The combined loan-to-value ratio shows the total amount of all loans secured by a property compared to the property’s market value. It helps lenders understand how much debt is tied to the property and the overall lending risk.

How is the CLTV ratio different from the LTV ratio?

The LTV ratio compares only the main home loan to the property value. In contrast, the CLTV ratio includes the primary mortgage plus any additional loans secured by the same property, giving lenders a broader view of total debt.

How do you calculate the CLTV ratio for a property?

To calculate CLTV, add the outstanding balances of all loans secured by the property. Then divide the total by the property’s current market value and multiply by 100. The result shows the percentage of the property financed through loans.

What is considered a good CLTV ratio for home loans?

A good CLTV ratio is usually 80% or lower. This indicates you have more equity in the property and less debt compared to its value. Lower CLTV ratios generally improve loan approval chances and may lead to better interest rates.

Does a higher CLTV ratio affect loan approval chances?

Yes, a higher CLTV ratio can reduce loan approval chances because it increases the lender’s risk. When total debt is high compared to the property value, lenders may charge higher interest rates, offer smaller loans, or apply stricter approval conditions.

Which loans are included in the CLTV calculation?

CLTV includes all loans secured by the same property. These may include the main home loan, a second mortgage, a home equity loan, a top-up loan, or a home equity line of credit. Adding them shows the property’s total debt exposure.

How can I improve my CLTV ratio before applying for a loan?

You can improve your CLTV ratio by reducing existing loan balances through prepayments, avoiding additional borrowing, or increasing your property’s value through improvements. Lower debt compared to property value helps create a healthier CLTV ratio.
