Ice Cream Scoops per Tub Calculator: Servings From Every Tub Size

How many scoops in a 3 gallon tub? About 96 four-ounce scoops on paper, and closer to 81 to 86 in a real shop once you count what sticks to the sides and the scoops that come out a little big.

That number changes with every scoop size and every tub. A 2 ounce kids scoop gets you twice as many servings. A 2.5 gallon tub gets you about a sixth fewer. And the number that really matters is not scoops. It is how much each scoop costs you and how much you make on every tub.

The calculator below does that math for you. Pick your tub, pick your scoop, and add your prices. Below it you will find ready-made tables for every Rapamar tub size, so you can plan even without the calculator.

1. Scoops per Tub Calculator

Choose a tub and a scoop size. Add your tub cost and menu price to see cost per scoop and profit per tub. Add how many scoops of one flavor you sell in a day to see how long a tub lasts.

Profit per tub here means your sales minus the cost of the ice cream. It does not count cones, cups, toppings, labor or rent, so treat it as a first check, not your final margin.

2. How Many Scoops in a 3 Gallon Tub

A 3 gallon tub holds 384 fluid ounces. Divide that by your scoop size and you have the count on paper. Then take off 10% to 15% for real-world losses. Here is how many scoops in a 3 gallon tub for each common scoop size:

The 3 gallon tub is the standard size for dipping cabinets, which is why most shop math starts here. Rapamar makes it in three shapes: 3 gallon rectangle, 3 gallon square and 3 gallon octagon. All three hold the same 384 ounces, so the scoop count is the same.

3. Scoops per Tub for Every Rapamar Tub Size

This table shows every tub we make, with the count on paper first and the count at 90% yield second. Click any tub to see its product page.

Counts are rounded down to whole scoops. Gallon sizes are nominal capacity, so a full tub that is filled to just under the lid will land a little lower. For gallon to liter conversions and how each shape fits a dipping cabinet, see our ice cream container size guide.

4. Why You Never Get the Full Count

The count on paper assumes every ounce in the tub ends up in a cone or cup. That never happens. Here is where the rest goes:

• Walls, corners and the bottom. The last of the tub is hard to scoop cleanly, and some ice cream always stays on the sides.
• Heavy scoops. A scoop that comes out a little over size, many times a day, adds up fast across a full tub.
• Tub fill level. A tub filled to just below the lid holds a little less than its nominal size.
• Samples and tastes. Every free taste comes out of the same tub.
• Melt and refreeze. Ice cream that softens and refreezes turns icy and coarse, and some of it ends up thrown out.

That is why we suggest planning for 85% to 90% of the count on paper. If your shop tracks tubs closely, use your own yield in the calculator. Count the scoops you rang up from one tub and divide by the count on paper.

5. Cost per Scoop and Profit per Tub

Once you know your real scoop count, the money math is simple:

A worked example

These are example numbers only, so swap in your own. Say a 3 gallon tub costs you $60, you serve a 4 ounce single scoop, and you sell it for $5.

Now see what happens when scoops run heavy. If staff serve 4.5 ounces instead of 4, the same tub gives about 76 scoops at 90% yield. Sales drop to $380, and you lose $50 of profit on a single tub. Over a busy summer with dozens of tubs, that is real money. Portion control is the cheapest profit boost an ice cream shop has.

6. How Big Is a Scoop?

Scoop size numbers can trick you. On a squeeze disher, the number is how many level scoops fill a quart, so a #16 disher holds 32 / 16 = 2 ounces. On a classic Zeroll ice cream scoop, the number follows a different scale: the Zeroll #16 is rated at 2.5 ounces and the Zeroll #10 at 4 ounces.

So two scoops with the same number can give you very different counts per tub. Always go by the ounce rating. Our scoop size chart lists every size from #4 to #100 in ounces, milliliters and grams, with a printable version for your shop.

Ounces on a scoop are fluid ounces, which measure volume. How much a scoop weighs depends on how much air is in the ice cream. Super-premium ice cream has about 25% to 50% overrun, while standard ice cream runs 100% to 120%, according to food scientist H. Douglas Goff. A denser ice cream gives a heavier scoop from the same tub, but the same number of scoops.

7. How to Get More Scoops From Every Tub

You cannot change the size of the tub, but you can change how much of it ends up sold.

• Use one scoop size per menu item. Give every station the same scoop for singles, and a smaller one for kids and samples.
• Keep the cabinet in the dipping range. The International Dairy Foods Association says ice cream is easy to dip between 6 and 10°F. Store back stock between -5 and 0°F.
• Do not let tubs soften and refreeze. The IDFA warns that repeated melting and refreezing hurts quality, which leads to waste.
• Weigh test scoops. Once a week, have each server scoop 5 portions onto a scale. Retrain anyone running heavy.
• Scrape the walls as you go. Working the sides down as the tub empties leaves less behind at the end.
• Track tubs, not just sales. Count how many scoops each tub really gave you. Put that number in the calculator as your yield.

8. Picking the Right Tub Size for Each Flavor

Scoops per tub also tell you how long a tub sits in your cabinet. Divide the scoops you can expect by the scoops you sell per day. If you sell 25 four-ounce scoops of vanilla a day, a 3 gallon tub lasts about 3 to 4 days.

A slow seller is a different story. If you only sell 8 scoops a day of a specialty flavor, the same 3 gallon tub sits open for more than 10 days. A smaller tub keeps that flavor fresher:

• Best sellers: 3 gallon or 12 liter RAPASTACK tubs, so you change tubs less often
• Steady flavors: 2.5 gallon tubs
• Slow sellers and specials: 1 gallon or 1.5 gallon gelato octagon tubs
• Batch freezer shops: the 7 quart rectangle is sized for Emery Thompson CB350 batches

Before you switch sizes, make sure the new tub fits your cabinet. Order a sample pack and try it in your wells first.
