Before I joined NerdWallet, I viewed credit card rewards skeptically. I didn’t think it was worth investing too much effort in managing multiple cards or strategically selecting which card to use for which purchase.

I liked keeping my financial life simple, and for a long time that meant using a basic, 1% cash-back card — the one that came automatically with my bank account.

Then NerdWallet opened my eyes to all that I was missing. Being surrounded by people who love researching credit cards and applying for new ones to get sign-up bonuses made me realize that with just a little extra effort I could be saving hundreds of dollars more a year. With two growing children straining my budget, that extra cash would come in handy.

Cash back for food

My first step was to take a close look at our monthly budget and figure out which card would give us the highest cash-back rate based on our spending categories. Since we spend so much on groceries, the Blue Cash Preferred® Card from American Express stood out: We could earn 6% cash back on up to $6,000 per year on our purchases at U.S. supermarkets, as well as 3% cash back at U.S. gas stations and U.S. department stores (and 1% cash back on all other purchases). Terms Apply.

While those rewards came with an annual fee of $95, a quick calculation showed that we would come out ahead. If we maxed out at the $6,000 limit, which we easily spend in a year on food, we would earn $360 in cash back for our grocery spending and likely another $90 on gas, given we spend about $250 a month on gas for our two cars.

After subtracting the annual fee, that would give us at least $355 extra a year. The Blue Cash Preferred® Card from American Express also includes a welcome offer: a $200 statement credit after you spend $1,000 in purchases on your new Card within the first 3 months. Terms Apply. That made the card even more appealing — an easy way to add $555 to my annual budget.

Defraying the cost of purchases

My next step was to get the Amazon Prime Rewards Visa Signature Card. Like many busy families, we rely on Amazon for almost all of our household purchases: A week doesn’t go by without several Amazon boxes landing on our doorstep.

Not only does the Amazon Prime Rewards Visa Signature Card give us 5% back on all of those purchases, but also 5% back at Whole Foods; 2% back at restaurants, gas stations and drugstores; and 1% back on all other purchases. While the card itself charges no annual fee, you must be an Amazon Prime member to get it, and a membership costs $119 a year.

Based on my estimates, we spend:

  • About $600 a month at Amazon (including snack food, clothing, sports equipment, household supplies, birthday presents and school supplies).
  • $150 a month at Whole Foods.
  • $300 a month at restaurants.

I calculated that using this card would give us an extra $43 or so in cash back a month, or more than $500 a year.

Adapting to our new habit

With both of these cards, I added my husband as an authorized user, so he can also rack up rewards with his everyday purchases. That has made it slightly harder for him to review his purchases and check for errors each month, since I’m the one who pays the bill, but we decided that hassle is worth the benefit of the added rewards.

I still keep my old 1% cash-back card in my wallet as a backup, but I try to make most of my purchases using either the Blue Cash Preferred® Card from American Express or the Amazon Prime Rewards Visa Signature Card.

When we first implemented our new credit cards rewards strategy, it was a little confusing: My husband kept asking me which credit card to use where; he never had so many choices before. But he soon began associating the Blue Cash Preferred® Card from American Express with the gas pump and regular grocery store, and the Amazon Prime Rewards Visa Signature Card with restaurants and Whole Foods. (I loaded that card into both of our Amazon accounts so it is used automatically.)

One unexpected benefit to our new system is that it has made us more disciplined spenders. Since our spending is primarily broken out on two different cards based on category, it’s easier for me to eyeball the statements and notice any aberrations or overspending each month. At first, I was shocked at how much we spent at Amazon, and we have been able to cut back on a few unnecessary items, like certain overpriced foodstuffs. (I’m looking at you, individually packaged seaweed snacks.)

Bumps along the way and goals

My new credit card rewards habit did not always go smoothly. Early on, before I was used to juggling my different credit card due dates, I accidentally forgot to make a payment and was immediately hit with a late fee.

Fortunately, when I emailed the card issuer to explain that I had simply forgotten, the charge was reversed. Then I set up automatic payments so the balances are always paid in full each month before their due date. That’s one less task to worry about.

I have to admit I am still not a perfect credit card maximizer. I hesitate to apply for a new card with an appealing sign-up bonus out of fear of complicating my finances further, and I know I could do much more to maximize my travel rewards, which is a goal for my husband and me as our children get older and easier to travel with. I have my eye on the Chase Sapphire Preferred® Card and a trip to Europe sometime in the next few years.

For now, I am grateful that I got over my fear of credit card rewards so that my family has an extra $1,000-plus this year — that’s money we can put toward savings, household expenses or a fun family vacation. When you’re trying to stretch a family budget, a little bit of cash back can go a long way.
