Blended Rate Calculator
A blended interest rate is the average interest rate across multiple loans or financial products, weighted by their amounts. It provides a more accurate picture of your total cost of borrowing when you have different loans at different rates.
🧾 Formula
Blended Rate=(A1×R1)+(A2×R2)A1+A2\text{Blended Rate} = \frac{(A₁ × R₁) + (A₂ × R₂)}{A₁ + A₂}Blended Rate=A1+A2(A1×R1)+(A2×R2)
Where:
- A₁, A₂ = Loan amounts
- R₁, R₂ = Corresponding interest rates (%)
You can extend this to more loans as needed.

📘 Example
Loan 1:
- Amount = $20,000
- Rate = 5%
Loan 2:
- Amount = $30,000
- Rate = 7%
Blended Rate=(20000×5)+(30000×7)50000=100000+21000050000=31000050000=6.2%\text{Blended Rate} = \frac{(20000 × 5) + (30000 × 7)}{50000} = \frac{100000 + 210000}{50000} = \frac{310000}{50000} = 6.2\%Blended Rate=50000(20000×5)+(30000×7)=50000100000+210000=50000310000=6.2%
