Ratehub Credit Card Calculator

Finding the right credit card can save you money and earn you rewards. Our RateHub Credit Card Calculator helps you compare interest rates, annual fees, and rewards programs to make an informed decision.

How the Credit Card Calculator Works

The calculator evaluates credit cards based on three key factors: interest rates, annual fees, and rewards programs. You input your spending habits and preferences, and the calculator ranks cards based on your needs.

Key Formula

The calculator uses a weighted scoring system where:

Interest rate (40% weight)
Annual fee (30% weight)
Rewards program (30% weight)

Each factor is normalized to a 0-100 scale before applying weights.

For example, a card with 15% APR, $95 annual fee, and 2% cash back would score:

Interest rate: (15/25)*100 = 60 points
Annual fee: (95/150)*100 = 63.3 points
Rewards: (2/3)*100 = 66.7 points

Final score = (60*0.4) + (63.3*0.3) + (66.7*0.3) = 58.6 points

Key Factors to Consider

Interest Rates

Variable APRs can change based on your credit score and market conditions. Look for cards with 0% introductory APR periods for balance transfers or purchases.

Annual Fees

Some premium cards charge $95-$500 annually. Consider whether the rewards justify the cost, especially for cards you won't use frequently.

Rewards Programs

Different cards offer cash back, points, or miles. Match your spending patterns to the card's rewards structure.

Pro Tip: Always check the card's terms and conditions for any hidden fees or redemption requirements.

Worked Example

Let's compare two cards for a traveler who spends $3,000/year on flights:

Card Feature	Card A	Card B
APR	18%	15%
Annual Fee	$0	$95
Rewards	1.5% cash back	3% cash back on flights
Calculator Score	52.5	61.5

Card B wins because it offers higher rewards on the traveler's primary spending category, despite the annual fee.

Are there any hidden fees I should watch for?

Yes, watch for foreign transaction fees, balance transfer fees, and inactivity fees. Always read the fine print before applying.

How do I maximize my rewards?
