How Much Slushy Mix Do You Need for 10, 30 or 100 Servings?
A measured planning guide for parties, food trucks and cafe counters. Work out your syrup, water and bottles before the first cup is poured - then plan for different sizes, flavours and machine capacities.
These are liquid-mix planning quantities, not guaranteed finished cup yields.
Start with the cup, not the bottle.
For 250mL servings, prepare 2.5L for 10 drinks, 7.5L for 30 drinks, or 25L for 100 drinks. With standard Slush It slushy syrup, that means using 500mL, 1.5L or 5L of concentrate respectively. Add four times as much cold water as concentrate.
Because the products come in 2L bottles, a single-flavour order requires one bottle for 10 drinks, one for 30 drinks and three for 100 drinks. That is the theoretical plan before any extra allowances. If you choose more than one flavour, calculate the bottle count for each flavour separately.
The result differs from a guest-number estimate: one person may take two drinks, and a 300mL cup consumes more mix than a 200mL cup. Count expected servings, not simply attendees.
Planning note: These values describe the liquid before freezing. Actual output depends on the measured fill volume, machine operation, sampling, spillage and drink presentation. Do not treat the table as a guaranteed frozen product yield.
The Slush It mixing rule
Five total parts of prepared mix, with no change in the recipe when you scale up.
Example: 500mL concentrate + 2L water = 2.5L prepared mix. This ratio applies to standard Slush It concentrates; sugar-free and other specialised products require their own label directions.
Make the right amount for 10, 30 or 100 drinks.
Choose one 250mL measured serve per drink for this starting plan. You can adjust the cup size in the next section.

Why these plans work: each 250mL serve uses 50mL syrup and 200mL water, before freezing and service losses. To change the number of portions, multiply those per-serve quantities by the number of drinks.
What if your cups are 200mL or 300mL?
A nominal cup capacity is not always the liquid volume you dispense. Use an actual measured portion for the best forecast. The table below shows nine exact, no-buffer recipes at a constant 1:4 dilution, rounded up only when purchasing whole 2L bottles.

Per serve: 40mL concentrate and 160mL water. Useful when the actual fill is small or you offer a child-size portion.
Per serve: 50mL concentrate and 200mL water. Our baseline for the three main planning tickets.
Per serve: 60mL concentrate and 240mL water. Even a small upgrade changes total stock requirements.
Keep a reserve without changing the mix.
A calculation that exactly covers your nominal cup count leaves no allowance for customer samples, spills, larger-than-planned pours or a guest returning for another drink. A 10% buffer is a simple planning illustration, not a manufacturer's promised wastage rate.
For 100 servings of 250mL, the base recipe is 25L. Adding a 10% planning reserve means budgeting 27.5L of liquid mix: 5.5L syrup plus 22L water. That still fits within three purchased 2L bottles of concentrate, although you must prepare and store batches within your equipment and food-handling requirements.
It is often more useful to buy sufficient concentrate but dilute it in stages. Do not load a larger batch into a small slushy machine or leave prepared mix sitting out simply because you purchased extra stock.
Two flavours can change the bottle count.
Totals alone can mislead you when you need separate syrup flavours. Every flavour comes in its own 2L bottle, so round up within each flavour, not just across the whole event. For example, both examples below supply a theoretical 100 servings at 250mL, without an added reserve.
60 Blue Raspberry: 15L prepared mix requires 3L concentrate, so buy two bottles. 40 Mango: 10L prepared mix requires 2L concentrate, so buy one bottle.
Total prepared volume: 25L. Total syrup used: 5L. Total bottles to purchase: 3.
50 Red Raspberry: 12.5L mix requires 2.5L concentrate, so buy two bottles. 50 Pink Lemonade: another 2.5L concentrate, so buy two bottles.
The same 25L of total prepared mix requires four purchased bottles because each flavour must be stocked separately.
For a 30-serving two-flavour party, even if one 2L bottle would cover the total 7.5L mix, offering two different flavours requires at least one bottle of each flavour. Choose your flavour split first; calculate stock second.
Do not combine the flavours in one tank just to avoid opening a second bottle. A dual-tank machine can display two distinct flavours when prepared separately, subject to its operating instructions. If you use different recipes, confirm each product's specific dilution instructions first.

Prepare by tank load, not by total order.
Knowing you need 25L for 100 serves does not mean that 25L belongs in your machine at once. Its actual bowl volume, maximum fill, minimum operating fill, number of tanks and ability to process refills determine the workable batches.
- Confirm the machine instructions. Check approved syrup-based recipes, minimum/maximum fill lines and the correct freezing cycle for your exact model.
- Test the actual serving volume. Fill your intended cup to the usual serving line using a measuring jug. Plan from that amount, not the cup's stated maximum capacity.
- Measure syrup separately. Add one part standard Slush It concentrate to four parts cold drinking water. Use marked food-safe jugs and keep the proportions constant.
- Load a permitted amount. Mix thoroughly in a clean, suitable vessel and transfer the approved quantity without exceeding the manufacturer's fill limit.
- Freeze and monitor service. Allow the proper freezing cycle. Keep a note of when refills are required; no single freezing time applies to all equipment.
- Replenish hygienically. Prepare subsequent charges using the same ratio. Follow the machine manual for refilling, cleaning and safe handling; follow the syrup label for opened-product storage.
Cost the portion you actually sell.
When planning slushy drink costs, start with the bottle price you actually pay. Divide that by the 10L of theoretical prepared mix from one standard 2L Slush It bottle, then multiply by your measured serve size. This produces a concentrate-only ingredient estimate - not a profit margin or a complete cost of goods sold.
For a worked illustration, imagine the concentrate costs A$16 per 2L bottle. A 250mL portion represents one-fortieth of a 10L prepared batch, making the theoretical syrup cost A$0.40 per 250mL serving. A 300mL pour costs A$0.48 using the same assumed bottle price.
Real costing must also include cups, lids, straws, water, electricity, machine depreciation, staffing, cleaning, overpour, samples and unsold mix. Do not promise savings based on a bottle-price calculation alone.
Frequently asked questions
How much slushy mix do I need for 10 drinks?
At 250mL per drink, 10 theoretical serves need 2.5L prepared liquid mix: 500mL standard Slush It concentrate plus 2L cold water. Buy one 2L bottle for a single flavour.
How much slushy mix do I need for 30 drinks?
Thirty 250mL serves need 7.5L prepared mix: 1.5L concentrate and 6L water. One standard 2L bottle contains sufficient syrup for this single-flavour base plan.
How much slushy mix do I need for 100 drinks?
One hundred 250mL serves need 25L prepared mix: 5L concentrate and 20L water. Buy three 2L bottles for one flavour without a planning buffer. A different mix of flavours can change the purchase count.
Is the Slush It ratio 1:4 or 1:5?
It is 1 part concentrate to 4 parts water. The final mix has five total parts. Calling the recipe 1:5 can cause mistakes if it is interpreted as one part syrup to five parts water.
How many 250mL slushies does a 2L syrup bottle make?
At the stated 1:4 dilution, it makes 10L of prepared liquid, equivalent to 40 theoretical 250mL portions before any machine hold-up, spills, samples or variation in measured serving volume.
Does a 10% buffer change the syrup-to-water ratio?
No. The extra stock allowance changes how much total mixture you plan for, but every prepared standard Slush It batch remains at one part concentrate to four parts cold water.
Can I make several smaller batches from one bottle?
Yes. The supplier lists smaller-batch examples such as 500mL syrup plus 2L water. Follow the bottle's current directions, keep opened syrup as instructed, and stay within your machine's permissible fill range.
What happens if I offer two slushy flavours?
Calculate the required syrup for each flavour separately, then round up to whole bottles for each flavour. For 100 x 250mL drinks split 50/50, each flavour needs 2.5L concentrate, so you need four bottles total: two of each.
Can I use the same numbers for Slush It Zero?
Not automatically. This article uses the verified dilution of the standard Slush It flavoured-mix collection. Sugar-free products and other formulas need their own current mixing instructions and compatible machine settings.
How far in advance should I prepare the mix?
There is no universal safe holding or freezing time. Follow product-label storage instructions and your machine manufacturer's operating and cleaning directions. Use cold water as recommended and plan service timing around a tested machine cycle.
