0 APR or Cash Back Calculator

When you're choosing between a 0 APR (zero annual percentage rate) offer and cash back rewards, it's important to compare both options to determine which will save you more money. Our calculator helps you make this comparison by showing you the equivalent interest savings and cash back value.

What is 0 APR?

A 0 APR offer means you won't be charged interest on your balance for a certain period. This is often offered by credit card companies as a promotional rate. The length of the 0 APR period varies, typically ranging from 12 to 21 months.

During the 0 APR period, any new purchases or balance transfers are added to your credit card balance without interest. After the promotional period ends, you'll be charged interest on your balance at the standard APR.

Key Points About 0 APR

No interest is charged during the promotional period
You must pay the balance in full before the period ends to avoid interest
Interest rates may increase after the promotional period
Some 0 APR offers require a minimum spending requirement

How Cash Back Works

Cash back rewards are a percentage of your purchases that are returned to you in the form of statement credits or rewards points. These rewards can be redeemed for cash, gift cards, or other rewards.

Cash back rates typically range from 1% to 5% on purchases, with some cards offering higher rates in specific categories. The cash back is calculated as a percentage of your total spending during a billing cycle.

Cash Back Calculation

Cash Back = (Total Spending × Cash Back Rate) / 100

For example, if you spend $1,000 and get 2% cash back, you'll receive $20 in cash back rewards.

Comparison Method

To compare 0 APR offers with cash back rewards, we calculate the equivalent interest savings and cash back value. This allows you to see which option will save you more money over time.

Our calculator uses the following formula to determine which option is better:

Comparison Formula

If (Interest Savings from 0 APR) > (Cash Back Value), then 0 APR is better.

Otherwise, cash back rewards are the better option.

By using our calculator, you can input your spending, interest rates, and cash back percentages to get a clear comparison of both options.

Example Calculation

Let's look at an example to see how the comparison works. Suppose you have a balance of $1,000 and you're choosing between:

A 0 APR offer for 12 months
2% cash back on all purchases

If you spend $1,000 during the 12-month period, you'll receive $20 in cash back rewards. If you use the 0 APR offer, you'll avoid interest charges for 12 months.

In this case, the cash back rewards ($20) are less than the potential interest savings from using the 0 APR offer, so the 0 APR option would be better.

When Cash Back Might Be Better

Cash back rewards can be more valuable if:

You can't pay off the balance before the 0 APR period ends
The cash back rate is higher than the interest rate you would pay
You have a high spending limit and can maximize cash back rewards

FAQ

How do I know if a 0 APR offer is right for me?

A 0 APR offer is right for you if you can pay off your balance before the promotional period ends. If you can't pay off the balance, you'll be charged interest at the standard APR, which may be higher than the cash back you would receive.

How do cash back rewards compare to interest savings?

Cash back rewards are typically a percentage of your purchases, while interest savings are based on the balance you carry. The value of cash back depends on your spending, while interest savings depend on the balance you have to carry.

Can I get both 0 APR and cash back rewards?

Some credit cards offer both 0 APR and cash back rewards. In this case, you can choose which benefit is more valuable to you based on your spending and payment habits.

What happens if I don't pay off my balance before the 0 APR period ends?

If you don't pay off your balance before the 0 APR period ends, you'll be charged interest at the standard APR. This can result in higher interest charges than the cash back you would receive.

How do I maximize cash back rewards?

To maximize cash back rewards, choose a card with a high cash back rate in categories you spend in most, and make sure to redeem your rewards for the maximum value.
