Scale any recipe from a small test batch to commercial production. Enter ingredients once, scale to any batch size, and see total costs automatically recalculated.
| Ingredient | Base Qty | Scaled Qty (g) | Scaled Qty (kg) | Unit Cost | Scaled Cost | % of Batch |

| Batch Size | Scale Factor | Total Ingredient Cost | Labour | Overhead | Total Production Cost | Cost per 100g |

This calculator scales any food recipe from a base batch weight to a target production batch, recalculating every ingredient quantity proportionally and projecting per-unit cost at any scale. It is designed for food founders transitioning from kitchen-scale recipe development to pilot batches and full co-packer production runs — where precision matters both for product consistency and cost control.
The core scaling principle is simple: Scaling Factor = Target Batch Weight ÷ Base Batch Weight. Every ingredient quantity is multiplied by this factor. A recipe developed at 500g that needs to run at 50kg has a scaling factor of 100. If your base recipe uses 380g of makhana, the scaled recipe uses 38,000g (38kg) of makhana. The calculator handles this arithmetic automatically for all ingredients simultaneously.
Beyond simple scaling, this tool generates a multi-batch projection table showing ingredient quantities and total production cost across a range of batch sizes from 1g to 1000kg. This is particularly useful for supplier negotiations — you can see exactly how much raw material you need at different production volumes and use that to justify volume commitments in exchange for better pricing. It also helps with production scheduling by making it immediately clear how many individual units each batch produces at your target fill weight per pack.
The calculator computes ingredient cost per unit using your specified fill weight per pack and the total ingredient cost of the scaled batch. This gives you a true ingredient cost baseline — the floor below which you cannot price your product without losing money on raw materials alone. Note that this is ingredient cost only; it does not include packaging, labour, co-packing fee, overhead, or logistics, all of which must be added to arrive at a full COGS figure.
While ingredient quantities scale linearly, several important parameters do not scale proportionally in food manufacturing. Understanding these non-linear factors is critical when briefing a co-packer or running a pilot batch.
Roasting times, mixing durations, and moisture equilibration periods often need adjustment at scale. A 500g kitchen batch of seasoned makhana may achieve even coating in 2 minutes of tumbling. A 50kg drum roaster batch may require 8–12 minutes to achieve equivalent coating uniformity due to the different surface-area-to-volume ratio and mechanical mixing dynamics. Always specify target water activity (aw) rather than just process time when briefing a co-packer.
Strong flavouring ingredients — chilli powder, dried citric acid, amchur, nutritional yeast — sometimes need to be scaled at less than 1:1 at very large batch sizes because their flavour intensity is perceived differently when mixed at scale. Industry rule of thumb: scale spices at 0.9x for batches above 100kg and adjust after tasting the pilot batch. Salt in particular tends to be perceived as more intense at large scale.
Your target batch size must match your co-packer's equipment capacity. A drum roaster rated for 30kg per batch cannot run a 50kg batch — you would need to run two batches and potentially recombine them, which introduces consistency risks. Always confirm equipment batch capacity before setting your target batch size, and consider building your batch size around equipment constraints rather than the other way around.
A complete co-packer brief for a dry snack product should include: target batch size in kilograms, ingredient list with exact quantities (use this calculator's output directly), ingredient specifications (grade, origin, moisture spec for each), process steps with target parameters (roasting temperature, time, tumbling speed), target aw of finished product, target fill weight per pack, and expected yield after process loss. Process loss — the percentage of raw material weight lost to evaporation, coating adhesion, and product rejected during QC — is typically 3–8% for roasted snacks and should be accounted for in your ingredient quantities. The calculator does not model process loss automatically, so add 5% to your ingredient quantities as a starting buffer.
Most Indian food co-packers have a minimum batch size of 25–50kg for dry snack products. Starting with a 25kg pilot batch allows you to validate your recipe at commercial scale, assess the co-packer's process consistency, and generate samples for retail buyer presentations — without committing to a large production run before you have confirmed demand.
Units per batch = (Batch Weight in grams × Yield %) ÷ Fill Weight per pack. For example, a 25kg batch at 95% yield with 100g packs gives: (25,000 × 0.95) ÷ 100 = 237 units. The multi-batch table in this calculator shows this projection across multiple batch sizes.
The co-packer needs FSSAI registration or licence (depending on their turnover). You as the brand owner also need FSSAI registration to sell packaged food commercially in India. For brands below ₹12 lakh annual turnover, Basic Registration applies. Above ₹12 lakh, State Licence applies. Above ₹20 crore, Central Licence is required.
Ingredient quantity scaling is mathematically exact — it is simple proportional arithmetic. Cost projections are as accurate as the per-unit cost data you enter for each ingredient. The non-linear process adjustments (spice scaling, moisture equilibration) are not modelled by the calculator and must be validated during your pilot batch.

Process parameters, yield figures, and product quality outcomes must be validated through pilot batch testing with a qualified food technologist.
