How Julia's Wallet Test compares a new card with the cards you already use

The short answer

A new credit card does not need a whole new way of shopping. Julia's question is whether it makes the life you already have a little easier or less expensive. She calls her method the Wallet Test: before getting excited about an offer, compare it with what you already use, on the purchases you actually intend to make.

The Wallet Score, from 1 to 100, is her way of comparing cards without changing the rules whenever a new one comes along. It gets a card onto the shortlist. Your own spending, your household and your plans decide whether the card stays there.

The answer may be a new card, a new card for one category only, or keeping what you have. Julia says keeping the current card might be the right result.

How the Wallet Score is built

For everyday rewards cards, the 100 points are split four ways:

• 55 points for useful value after costs.
• 20 points for how freely you can use the rewards.
• 15 points for how easy the card is to manage.
• 10 points for purchase and trip protection.

Every card faces the same 3 annual spending budgets: everyday shopping, more food spending and more travel. Each totals $30,000. Opening bonuses are left out, and the test checks what happens if the biggest useful benefit goes unused. A card should not need a perfect year to make sense.

Cards for building credit, running a business or paying down debt get a clearly labeled test for that job. Julia would not compare a credit-building score with a rewards score and assume the higher number wins. The full breakdown sits in the companion guide, so you can see what drove each result.

A score is also not a verdict on your family. A hotel card might score modestly as an everyday card and still be worth keeping for a night you would actually use.

From the score to your own wallet

Take a grocery card. Julia would start with the usual stores and check how much of that shopping qualifies for the higher rate. A supermarket limit or an excluded store could change the choice. Then she would include the annual fee.

She would not count all of the new card's rewards as an improvement when her current card already earns something. Keeping that card might be the best answer. Or she might use the new card for one category and keep the old one for everything else.

A better rate also is not enough on its own. On $100 of qualifying spending, a 6% card earns $6 where a 2% card earns $2, which is $4 more. But if getting that rate meant paying a $5 fee that earned no rewards, she would keep only $1 instead of $2. She would prefer the cheaper purchase.

What could change the answer

Julia stays with a decision long enough to see what would change her mind. Spending might shift, a different store might qualify, or a hotel might be cheaper when booked directly.

• Monthly credits: a credit might reduce a subscription you already pay. If you would never buy that service, do not treat its advertised amount as money saved.
• Welcome bonuses: a bonus belongs in the first year. Compare later years separately, once the extra reward or fee waiver ends.
• Points: find a booking you could actually use and include any cash still due. Count another card's annual fee if you need it to reach that redemption. A large balance is only useful if it can pay for something you want.

Your household and your debt

Ask how the card works for the rest of your family. A second card might share the account's credit without creating another allowance. A travel perk might cover you while leaving your partner to pay. Count the arrangement you would actually need, including an extra cardholder fee if one applies.

If you are paying interest on debt, work on the repayment plan before chasing reward differences. If you pay in full, a small improvement that is easy to maintain may be enough.

Before you act

Bring a recent statement and the cards you already own. You do not need an elaborate collection to find out whether another account would help. Julia's product terms are checked and dated in the companion notes, but you should still check the actual application and the current benefit guide, because offers and account-specific benefits can change.

The dollar amounts here are Julia's worked examples, and card terms may have moved since the lesson was recorded. She gives numbers when they help a choice, with the fees and the useful benefits included. The aim is a wallet that fits your life, whether that means adding a card or keeping what already works.
