True Price Calculator

A shelf price tells you very little. By the time a store sale, a clipped coupon, a rebate app and your card have each taken their cut, the real cost of an item can be half the number on the tag. The catch is that some of that money arrives today and some of it arrives weeks or months later, and some of it only arrives once an app decides you have earned enough.

This calculator does both jobs. Enter what you have for one item and it prints your true price, flags stacks that stores are known to block, and shows when each piece of the money actually reaches you.

Payout rules last checked against each company’s own pages on September 28, 2026.

How do you use the calculator?

1. Type the regular shelf price and pick in store or online. Rakuten only counts online, so it switches off for in-store trips.
2. Fill in whatever comes off at the register: the store’s sale, a coupon clipped in the store app, and a manufacturer coupon if you have one.
3. Fill in whatever pays you back afterwards: an Ibotta rebate you activated, Fetch points for the receipt, your card’s cash back rate, and a Rakuten rate for online orders.
4. Optional: open “Add what’s already in your apps” and type your current balances. The timeline then tells you whether this purchase gets you over each app’s payout line.

Leave any box empty if it doesn’t apply. Nothing you type is saved or sent anywhere; the math runs in your browser and disappear when you close the page.

What does “when the money reaches you” mean?

Most savings math leaves this part out. A dollar off at the register and a dollar of rebate are not the same dollar. The first one never leaves your account. The second one sits in an app until you meet that app’s rules, and it can’t pay a bill until then.

• Register savings are the only money you are guaranteed on the day.
• Ibotta lets you withdraw once your balance reaches $20, you have redeemed at least one offer, and at least 7 days have passed since that first one. Ibotta says the money then takes 0 to 5 days to arrive, depending on how you withdraw.
• Fetch pays in points, not cash. Fetch describes 1,000 points as worth roughly $1 in gift cards, and a redeemed reward takes 72 hours to process.
• Rakuten pays by quarter, on February 15, May 15, August 15 and November 15, and only if you have at least $5.01 in cash back. Anything below that rolls into the next quarter.
• Your card pays on your issuer’s schedule, which your card’s terms set.

That is why a small rebate can feel like it vanished. $1.50 from Ibotta is 7.5% of the way to a $20 withdrawal. It’s real money, but it’s money you’ll see on a later trip, not this one.

What does a worked example look like?

The calculator opens on the same illustrative example we use in how to stack cashback apps: a name-brand laundry detergent with a $12.99 shelf price, bought in store.

• Shelf price: $12.99
• Store sale, −$3.00: $9.99
• Store coupon, −$2.00: $7.99 paid at the register
• Ibotta rebate, $1.50 back: $6.49
• Rewards card, 2% of $7.99 = $0.16 back: $6.33 true price

You hand over $7.99 and end up paying about $6.33, which is 51% off the tag. $5.00 of that saving happened at the till. The other $1.66 is spread across an Ibotta balance and a card statement, and arrives on their timetables. Change any number in the calculator above and the receipt updates as you type.

How is the true price calculated?

In plain terms:

• Paid at the register = shelf price − store sale − store coupon − manufacturer coupon. It never goes below $0.00.
• Card cash back = your card rate × what you paid at the register. Your card earns on what it was charged, after coupons, not on the shelf price.
• Rakuten = its rate × what you paid, and only for online orders.
• Fetch = points ÷ 1,000, because Fetch values 1,000 points at roughly $1.
• True price = paid at the register − Ibotta − Fetch − card − Rakuten.

Everything is before sales tax, and the Rakuten date is the earliest possible check for a purchase made today.

Which combinations does it warn you about?

• Store coupon plus manufacturer coupon on one item. Kroger’s published coupon policy says: “Limit one Store/Manufacturer coupon (paper or digital) per item purchased.” Other chains write their own rules, so the calculator asks you to check your store rather than assuming.
• An Ibotta rebate on a couponed item. Individual offers can carry their own restrictions. The offer’s terms in the app are the only reliable answer.
• Rakuten on an in-store trip. Portal cash back only tracks when you click through to a store’s website and buy online.
• Discounts bigger than the price, or an unusually high card rate. This is usually a typo and occasionally a real money-maker. Either way it’s worth a second look.

What can’t this calculator tell you?

It doesn’t know which offers are live in your area this week, whether your store will accept a particular coupon, or whether a receipt will be approved. It covers Ibotta, Fetch and Rakuten because those are the apps whose payout rules we checked on their own help pages; other apps set their own thresholds. Companies change these rules without notice, which is why the checked date sits at the top of this page. Treat every figure as an estimate, not financial advice, and check the app before counting on a payout.

Frequently asked questions

Does the calculator save my numbers?

No. It has no account, no login and no database. The calculation happens on your phone or computer and nothing you type is sent to us.

Why isn’t my card cash back worked out on the shelf price?

Because your card only sees the amount it was charged. If coupons took a $12.99 item down to $7.99, a 2% card pays 2% of $7.99.

Can I use Ibotta and Fetch on the same receipt?

Usually, yes, because they work differently: Ibotta pays on specific offers you activate, while Fetch gives points for scanning the receipt itself. We compare them properly in Ibotta vs. Fetch.

Why does the Rakuten date look so far away?

Because Rakuten pays quarterly. A purchase made early in a quarter waits longer than one made near its end, and a balance under $5.01 waits for the next check. We explain the full cycle in how Rakuten works.
