Credit Card Debt Calculator Methodology

Credit card interest kicks in on the remainder of your unpaid balance each month. For the above calculator, we assumed you begin with a set balance, and begin to pay it off over time. The interest for each month is equal to the periodic rate multiplied by your balance after a payment is applied.

The periodic rate varies month to month, depending on the number of days in a billing period. In order to approximate this, we divide the card APR by 12, to get a monthly periodic rate.

The interest rate is then added to the balance after payment, and carries over into the next month where the process is repeated.

How We Calculate Rewards: ValuePenguin calculates the value of rewards by estimating the dollar value of any points, miles or bonuses earned using the card less any associated annual fees. These estimates here are ValuePenguin's alone, not those of the card issuer, and have not been reviewed, approved or otherwise endorsed by the credit card issuer.

Example of how we calculate the rewards rates: When redeemed for travel through Ultimate Rewards, Chase Sapphire Preferred® Card points are worth $0.0125 each. The card awards 2 points on travel and dining and 1 point on everything else. Therefore, we say the card has a 2.5% rewards rate on dining and travel (2 x $0.0125) and a 1.25% rewards rate on everything else (1 x $0.0125).
