Common questions
Is CardFit free?
Yes. You can find, compare, and save cards without an account. CardFit is free to use. No one can pay to change these results. If a card issuer ever pays us, for example for a referral, we will label it clearly.
Does CardFit check my credit?
No. CardFit never checks your credit or asks for your Social Security number. It uses only the rough monthly spending you enter.
What is the match score?
It is Koko Finance’s rating of how closely a card fits your goal and spending. Higher means a closer fit. It is not a dollar value or a chance of approval.
Where does the card data come from?
Koko Finance supplies card details, rankings, and reward math. Its catalog does not cover every card, so confirm current rates, fees, and offers with the issuer before you apply.
Will I be approved?
CardFit does not predict approval. Each issuer decides using its own criteria.
Where are my saved cards?
Without an account, saves stay in this browser on this device. Signed-in saves are stored with your account.
