| Example: | Outstanding loan balances are $3,500, $3,200, and $5,500 respectively---for a total of $12,200. The current interest rates for the loans are 7%, 5%, and 9%, respectively. |
| $3,500 x .07 = $245 $3,200 x .05 = $160 $5,500 x .09 = $495 |
| Example: | $245 + $160 + $495 = $900 $900 ÷ $12,200 = .07377 or 7.377% |
| Example: | 7.377% is rounded up to 7.5% |
