Calculate Average Interest Rate

In order to save on interest, it may in some cases be advantageous to transfer the balance of one or several credit cards to another card with lower interest rates or to another form of less costly credit. Combine up to fifteen debts and calculate the average interest rate of this consolidated debt.

Note: to avoid errors in calculation, enter only numeric characters and decimal points in the three right-hand columns. The use of commas, letters or dollar signs in these columns will cause an error.
