I have a weird habit of tracking things. Side hustle income, bank bonuses, even how much gas I use on a typical week. So at some point last year, I decided to start tracking every single discount, coupon, or cashback offer I used too. Just to see what it actually added up to.
I figured it would be a small number. Maybe enough for a nice dinner out. I was wrong, and honestly the results kind of surprised me.
Why I Started Tracking This in the First Place
It started almost by accident. I was buying something online, applied a promo code out of habit, and thought “huh, I wonder how often I actually do this.”
So I made a simple spreadsheet. Every time I used a coupon code, cashback app, or any kind of discount, I logged the item, the original price, and how much I saved. Nothing fancy, just three columns and a running total at the bottom.
The plan was to check back in after a year and see what the number looked like.
The First Few Months Felt Pretty Underwhelming
For the first month or two, the savings were small. A few dollars here, ten bucks there. Mostly grocery coupons and the occasional cashback from an app I already had on my phone.
I almost stopped the experiment around month three because it felt like I was tracking pocket change. But I kept going anyway, mostly out of stubbornness.
Looking back, that early phase was useful though. It showed me how often I was leaving small discounts on the table without even thinking about it.
Then I Started Being More Intentional About It
Around the four month mark, something shifted. Instead of just applying a coupon when one happened to be available, I started actually looking for one before buying anything online.
This is where Coupon Mister came into the picture for me. Before checking out on most online purchases, I’d do a quick search there to see if there was a working code for whatever site I was buying from. Sometimes there was nothing useful, but often enough there was a code that knocked off 10 to 20 percent, which is a lot more than the spare change I was tracking earlier.
That one small habit change made a noticeable difference in the numbers from that point forward.
The Year End Total Actually Surprised Me
When I finally added everything up at the end of the year, the total came out to just over $740 in savings. That’s not life changing money, but it’s also not nothing. It’s basically a free flight, or a decent chunk toward a car repair.
What struck me more than the total was how it built up. Around 60 percent of those savings came in the second half of the year, after I started being more deliberate about checking for discounts before buying instead of after.
It reminded me a lot of the math behind side hustles, where every extra dollar earned can be redirected toward your goals, whether that’s debt, savings, or just breathing room in your budget. Except in this case, the dollars were saved instead of earned, which honestly feels just as good.Â
What Actually Made the Biggest Difference
Looking back at the spreadsheet, a few things stood out. Cashback apps on groceries and everyday purchases added up steadily over time, even when each individual amount felt small. Some of the apps I leaned on most are ones I’d already written about before, since I tend to stick with the cashback apps that actually pay out reliably rather than chasing every new app that shows up.
Coupon codes for bigger purchases, like electronics or annual subscriptions, gave the biggest single boosts. One code alone saved me close to $60 on a renewal I was about to pay full price for.
The smallest but most consistent category was just store-brand swaps combined with small percentage-off codes. Individually they barely registered, but stacked over twelve months, they quietly made up a decent chunk of the total.
Why I’m Going to Keep Doing This
Honestly, the tracking itself became kind of fun after a while. It turned into a small game of “can I find a better deal before I check out,” instead of feeling like a chore.
It also tied into something I think about a lot with money in general. Small, repeatable habits tend to beat big, occasional efforts. That’s basically the same idea behind the reverse latte factor concept, where small consistent amounts add up to something meaningful over time without requiring any major sacrifice.
I’m planning to keep the spreadsheet going this year too, just to see if the number grows now that the habit feels more automatic than it did at the start.
Final Thoughts
A year of tracking discounts taught me that small savings really do add up, especially once you start looking for them on purpose instead of by accident. The total wasn’t huge, but $740 for barely any extra effort is hard to argue with. If you’ve never tracked this kind of thing before, even a rough spreadsheet for a few months might show you more than you’d expect.
