Weighted Average Interest Rate Calculator


Use the spreadsheet below to calculate your total loan balances and the associated weighted average interest rates for use in our student loan calculator

Input each loan balance and its associated interest rate into the chart. You weighted average will be displayed on the right size of the chart.

Note: If you are using the calculator in order to use our PAYE vs REPAY spreadsheet, remember to only include your PSLF-eligible federal loans into this calculator. However, the calculator below will give you a true weighted-average interest for any/all debt, if you wish (e.g. student loans + credit card + auto, etc).
