The concept of "Power Payments" will help you repay your loans faster and reduce your total interest payments. Consider a situation where you have 3 loans: Loan A has a loan payment of $500/month and an interest rate of 5% APR; Loan B has a payment of $200/month and an interest rate of 3% APR; Loan C is a credit card with a payment of $300/month and interest rate of 18% APR.

If you have an extra $100/month that you can pay towards your loans, to which loan would you first apply the extra $100/month payment so that you would save yourself the most in interest?
