Definition
The blended rate is a financial metric used to determine an average rate that reflects different interest, tax, or billing rates over various time periods or for various portions of the principal amount. It is a weighted average rate, taking into account the time period each rate is applied and/or the proportion of the amount subject to each rate.
Examples
Example 1: Blended Interest Rate for Mortgages
If you refinance an existing mortgage with a $200,000 balance and a 3% interest rate, combining it with a new loan for an additional $50,000 at a 5% interest rate, the blended rate is calculated as follows:
\[ \text{Blended Rate} = \frac{(200,000 \times 0.03) + (50,000 \times 0.05)}{200,000 + 50,000} = \frac{6000 + 2500}{250,000} = 3.4% \]
Example 2: Blended Tax Rate
A corporation might have different tax rates applied to different income brackets. If $100,000 is taxed at 10%, and $150,000 is taxed at 20%, the blended tax rate is:
\[ \text{Blended Tax Rate} = \frac{(100,000 \times 0.10) + (150,000 \times 0.20)}{100,000 + 150,000} = \frac{10,000 + 30,000}{250,000} = 16% \]
