// Credit Card Rewards Calculator
//
// Credit Card Rewards Calculator helps users determine
// the monthly and annual amounts they can earn from credit cards
// paying percentage rewards (typically 1% or 2%) on eligible purchases.
// The calculator also computes the amount of interest that will be paid
// (at various APR rates)if users carry balances at various levels.
// The purpose is to show users how carrying a credit card balance
// diminishes the rewards earned and to help them determine the break-even point.
