How Do Cashback Apps Make Money? Stores Pay, You Get a Cut

Stores and brands pay cashback apps to send shoppers their way. The app keeps part of that payment and passes the rest to you. Most apps also sell ad space and paid placement inside the app. Some share or license shopping data. And balances that expire or get eaten by inactivity fees never get paid out at all. If you’re wondering whether the model itself is a red flag, see are cashback apps legit. The short version: it isn’t, but you should know which deal is running behind the app on your phone.

The four ways money reaches the app

• Affiliate commission. A store pays the app for each sale it refers. Rakuten and TopCashback work this way.
• Pay per redemption. A brand pays every time someone redeems its offer, plus a fee on top. This is Ibotta’s core business.
• Profit share on extra sales. The store pays only for sales the app can show it wouldn’t have made otherwise. This is Upside’s model.
• Side revenue. This covers paid placement, in-app ads, data licensing, and balances that are never cashed out. Ibotta calls that last one “breakage”.

Rakuten: a commission, split with you

Rakuten says stores pay it a commission for referring shoppers, and it “keeps a portion of this commission and shares the rest with you as Cash Back.” The same page says members have earned over $4.6 billion in cash back since 1999.

The marketing leaves two things out:

• Rakuten doesn’t say what percentage it keeps. You see your rate, but never the store’s full commission.
• Rakuten’s advertising disclosure says retailers can also pay to boost their brand, which can get them featured on the site and in emails. So a store at the top of the app isn’t automatically your best deal.

Cash back is calculated on the net purchase. That excludes tax, shipping, fees, discounts, returns and warranties. The purchase has to go through a Rakuten link in the same browsing session, and disabled cookies block tracking. If the store’s commission never fires, nobody gets paid, including you.

Ibotta: brands pay every time you redeem

Ibotta is a public company, so its numbers are on file with the SEC. Its 2025 annual report calls it “a success-based marketing solution”. Brands pay only when a promotion leads to a purchase. They’re billed for the value of the reward plus a fee for each redemption.

What the filing shows for 2025:

• Over 900 clients, representing over 3,100 consumer packaged goods brands.
• Total revenue of $342.4M, down 7% from $367.3M.
• Redemption revenue of $297.2M. Revenue from Ibotta’s own app and website fell $33.8M, while third-party publishers (mainly the new Instacart and DoorDash partnerships) added $22.2M.
• Ads and other revenue of $45.2M, down 23%. This covers display ads, tiles and sponsored offers in the app.
• Ibotta also licenses data to clients and earns affiliate revenue.

Ibotta reports revenue “net of rewards”. So the $342.4M is what it booked after your rewards came out, not the total brands paid. Revenue per redemption was $1.11 on Ibotta’s own app and website and $0.79 through partner apps, an average of $0.87.

Here’s some rough math using only the filing’s figures. 340.8M redemptions divided by 18.2M redeemers is about 19 redemptions per person in 2025, or roughly one and a half a month. $342.4M in revenue divided by 18.2M redeemers comes to about $18.80 per person for the year, across every channel.

The filing defines breakage as user earnings “not expected to be cashed out due to inactivity”. It treats breakage as an accounting estimate but gives no dollar figure. If you want to make sure your own balance isn’t part of it, here’s how to cash out Ibotta.

Upside: paid only for sales the store wouldn’t have made

Upside’s contract methodology for grocery stores (last updated July 2023) compares you with a control group of shoppers who have a similar spending history. Spending above the control group counts as “incremental revenue”. That figure can’t go below zero, and it can’t exceed the sales credited to Upside.

The formula:

1. Incremental revenue × the store’s average gross margin = incremental gross profit.
2. The store funds your cash back up to that profit, and Upside covers anything above it.
3. Upside’s fee = its profit-share percentage × (incremental gross profit minus promotional costs).

Upside doesn’t publish real rates, so every number in this example is our assumption. Say Upside credits you with $100 of extra spending at a grocer with a 25% margin. That’s $25 of extra gross profit. If your cash back cost $5 and Upside’s share were 30%, Upside would earn 30% of $20, which is $6. The grocer keeps $14.

Upside earns the most when you change where you shop. Spending you’d have done anyway earns it nothing under this formula.

Your data

Fetch is private and publishes no financials, so we can’t tell you how its revenue breaks down. Its privacy policy is clearer about your data. By using the app, you “consent to Fetch disclosing your personal information to our brand partners.”

• Fetch says it doesn’t share phone numbers, precise geolocation or consumer health data.
• It admits these disclosures may count as a “sale or sharing” of personal data under state privacy law. That covers identifiers such as IP address and device IDs, internet activity and general geolocation, shared with analytics and advertising partners. You can opt out through its “Do Not Sell or Share My Personal Information” link.
• It doesn’t treat de-identified or aggregated data as personal information. Third parties may use that data to study shopping behavior.
• If you connect your email, Fetch can act “as your agent” to pull purchase details from your digital receipts.

Our full take is in is Fetch Rewards legit. Ibotta licenses data to clients too, and its bank transfers run through Plaid. Linking a bank gives an app and its partners a view into your finances, so decide whether that’s worth a few dollars a month.

TopCashback’s “no cut” pitch

TopCashback says it makes money from bonuses retailers pay for high shopper volume, plus on-site ads and sponsored content. It says this lets it run “without taking a cut from your Cash Back.” It doesn’t say it passes on 100% of the commission, so treat “no cut” as the company’s own claim.

Money you never collect

Fees and expiry rules decide how fast an idle balance shrinks:

• Rakuten: After 12 months with no shopping, it may take $5 a month from your balance, but never below zero.
• Ibotta: $3.99 every 30 days after 180 days with no redemption.
• Upside: Rewards expire after 6 months with no earning or redeeming.
• Fetch: Points expire after 90 days of inactivity. Fetch gives 30 days’ notice, and expired points can’t be recovered.

Shutdowns are worse. Dosh closed in February 2025, and balances left after 23 Feb were forfeited. Shopkick shut down in March 2026, and its points can no longer be used.

What it really pays per hour

No app publishes per-hour earnings. Your real cost is the extra steps (clicking through, scanning receipts, chasing missing cash back) plus the wait.

An example with assumed figures: you spend $200 net in early March at a store offering an assumed 3% on Rakuten. You earn $6.00, which clears the $5.01 minimum. If the purchase takes the full 14 weeks to confirm, it misses the 15 May payment and arrives around 15 Aug. That’s more than five months for $6. The Rakuten payout calendar explains the timing.

Fees eat into small balances too. Upside charges $1 on bank cash-outs under $10, so cashing out $8 costs you 12.5%.

Complaints worth knowing

• Tracking failures. Ad blockers, disabled cookies or switching sessions can stop a purchase from tracking. Rakuten gives you 90 days to report missing cash back.
• Payout methods disappearing. Upside dropped PayPal for most accounts in late 2025 and for the rest on 14 Aug 2026. PayPal Rewards stopped cash redemptions on 1 Aug 2026.
• Browser extension lawsuits. In separate suits, the Honey and Capital One Shopping extensions are accused of interfering with other people’s affiliate commissions. Judges have let key claims go forward, but neither case has a finding of liability. Since June 2025, Google has required Chrome extensions to disclose affiliate programs and to get user action before applying affiliate links.

Taxes, briefly

The IRS says a cash rebate from a dealer or manufacturer on something you buy “isn’t income.” Prizes and awards are taxable. Rakuten’s terms say referral and promotional bonuses may be taxable, and Upside may ask for your tax ID and issue a 1099. For 2026, the reporting threshold for 1099-MISC rose to $2,000. That changes when you get a form, not whether something is taxable. This is general information, not tax advice, so check your own situation with a tax professional.

Better alternatives by shopping style

• You shop online often: Rakuten. It has a simple commission split, a $5.01 minimum and quarterly payouts.
• You buy name-brand groceries: Ibotta. Brands fund the offers, but you need $20 to withdraw.
• You’ll switch stores for a better deal: Upside. Its model rewards changing where you shop. Watch the $1 fee on small cash-outs.

FAQ

Why would a store pay an app to give me money? It’s marketing that only costs the store when a sale happens. Rakuten’s disclosure says merchants pay because it sends shoppers to their sites and stores.

Do cashback apps sell my data? Fetch’s privacy policy says its sharing may count as a “sale” under state privacy law, and it offers an opt-out. Ibotta licenses data to clients.

Does the app profit if I never cash out? Ibotta’s filing counts expected unclaimed balances (breakage) as an accounting estimate. Inactivity fees and expiry rules at the other apps shrink idle balances.

Is cash back taxable? The IRS says rebates on purchases aren’t income. Referral and sign-up bonuses can be, so keep records.

Use it if, skip it if

Use it if

• You’re fine with the app taking a cut of marketing money the store would spend anyway.
• You’ll cash out regularly, so expiry and inactivity fees never hit you.
• You’ve read the privacy policy and accept what it shares.

Skip it if

• You won’t reach the payout minimum before the balance expires or fees start.
• You don’t want brand partners seeing your receipts or a bank-data service linked to your account.
• You’d switch to pricier stores to chase an offer, which is exactly the behavior the app gets paid to produce.
