What Is a Blended Interest Rate?

A blended interest rate is the combined interest rate you pay when you have multiple loans with different interest rates. It represents the weighted average of those rates based on how much you owe on each loan.

In simple terms, if you have two or more loans, the blended rate helps you understand the overall interest rate you are paying across all your outstanding balances.

The loan amount plays an important role in this calculation. A loan with a larger outstanding balance has a greater impact on the final blended rate than a smaller loan. This means the combined rate is not simply the average of the individual interest rates; each rate must be weighted according to its loan balance.

Simple Example

Suppose you have two loans:

• Loan 1: $5,00,000 at an annual interest rate of 5%.
• Loan 2: $10,00,000 at an annual interest rate of 8%.

Since the second loan has a larger outstanding balance, its interest rate will have more influence on the combined rate.

To calculate the blended interest rate, multiply each loan balance by its interest rate, add the results, and divide the total by the combined loan balance.

The calculation gives you a blended interest rate of 7%.

This means that, instead of looking at each loan separately, you can use 7% as the weighted average interest rate to understand your overall borrowing cost.

A blended interest rate is particularly useful when combining existing loans, refinancing debt, or comparing different borrowing options.

How to Calculate a Blended Interest Rate

Calculating a blended interest rate involves combining the outstanding balances and interest rates of multiple debts to find their overall weighted average interest rate. This is useful when you have several loans with different interest rates and want to understand the effective interest rate you are paying across all of them.

The blended rate formula is:

Example: Blended Interest Rate Calculation

Suppose you have three debts with the following balances and annual interest rates:

Step 1: Calculate the annual interest for each debt.

• Debt 1: $20,000 × 6% = $1,200
• Debt 2: $25,000 × 8% = $2,000
• Debt 3: $15,000 × 8% = $1,200

Step 2: Calculate the total annual interest.

Step 3: Calculate the blended interest rate.

Blended Rate Analysis Results

Therefore, the blended interest rate across all three debts is 7.33% per year. This means that, based on their outstanding balances, the three debts have a combined weighted average annual interest rate of 7.33%.
