Why Food Margins Lie: The Gap Between Gross, Contribution, and Cash

What gross margin actually measures, and what it ignores

Gross margin in FMCG is arithmetically simple: revenue minus cost of goods sold, expressed as a percentage of revenue. In a restaurant context, COGS refers only to raw materials: the protein, the grain, the dairy, the oil. Nothing else enters that calculation, and that exclusion is the source of most of the confusion.

A QSR selling at ₹250 per plate, with raw material costs of ₹ 90, reports a 64% gross margin. That number carries significant weight in investor presentations. The problem is that everything it excludes is far larger than what it captures. Those exclusions account for between 40 and 55 additional percentage points of cost before the business reaches any actual profit.

Even with raw materials at approximately 32% of revenue, a reasonably efficient number for an Indian QSR, the business carries another 47 to 52 rupees of costs per 100 rupees of revenue that never enter the gross margin line. According to the NRAI India Food Services Report 2024, India’s organised food services segment is projected to grow at 13.2% CAGR through 2028. The growth is genuine, and the margin math within it requires deliberate attention from every operator participating in it.

Labour cost is the number that never holds still

In most financial models, labour is projected as a stable percentage of revenue, often 22 to 28%, and left there. The actual behaviour of labour cost in an operating food business is considerably more volatile.

Four components sit under the labour line: direct kitchen crew wages, service or delivery staff wages, manager and supervisor compensation, and the costs of attrition: recruitment, onboarding, training, and the productivity dip during a new hire’s learning period. The fourth category rarely appears cleanly on a P&L, but its economic impact is real and recurring.

How labour scales, and when it does not

Labour in food and beverage is semi-fixed rather than variable, which means a kitchen requires a minimum crew regardless of order volume. When a Sunday brings three times the footfall of Monday, the existing crew is pushed harder. When Tuesday brings half the typical covers, that same crew still shows up and gets paid, and the cost per cover nearly doubles. This semi-fixed nature is precisely why contribution margin matters more than gross margin when evaluating outlet viability.

Sleepy Owl Coffee, a ready-to-drink and cold brew brand in the Rukam Capital portfolio, offers a useful contrast here. By placing labour upstream in manufacturing rather than at the point of service, the business sidesteps the semi-fixed crew problem that haunts every café or counter-service format. The trade-off is higher packaging cost and supply chain dependency. But the labour line becomes considerably more predictable, which is a structural advantage that compounds as the brand scales.

Rent does not negotiate when your tables are empty

Real estate is the highest fixed cost in a traditional dine-in or QSR format, and it has a property that makes it uniquely dangerous: it does not move in step with revenue. A lease signed at 12% of projected revenue becomes 24% of revenue when the outlet underperforms by half, and the landlord is not party to that renegotiation.

Standard guidance suggests keeping occupancy costs, rent plus CAM plus property-level utilities, below 15% of revenue. In practice, operators in high-footfall metro locations sign leases priced at 12 to 14% of their revenue projections. When actual revenues fall short, those occupancy costs migrate into a structurally uncomfortable range.

The rise of cloud kitchens was partly a structural response to this. Eliminating the dine-in footprint reduced occupancy costs from 12–18% of revenue down to 6–9%. But cloud kitchens introduced a different cost that did not exist in the traditional format: platform commission, which scales with every delivery order.

Every order on Swiggy or somato comes with a quiet partner

The aggregator model has restructured FMCG economics in India more than any single factor in the past five years. Delivery platforms bring real reach and genuinely incremental demand that most brands could not replicate through direct channels alone. But they come at a cost that, when not modelled correctly at the order level, fundamentally changes the contribution math.

As Business Standard reported in August 2024, Swiggy extended its service fee to be calculated on the gross order value, which includes GST and packaging, for restaurant partners across non-metro areas. Commission is now charged on a number larger than the net food value. Rapido’s June 2025 entry at 8–15% commission, in partnership with NRAI, illustrates how widely the platform cost burden has been recognised.

Packaging: the cost that grew with delivery

Delivery brought packaging costs at a scale that dine-in formats do not carry. Go DeSi, which sells traditional Indian snacks and impulse foods across delivery, modern trade, and quick commerce channels, carries packaging as a meaningful variable cost on every unit. A well-packaged delivery order in 2025 costs ₹18 to ₹55 per order depending on format. For an average order value of ₹200, this represents 9 to 27% additional cost on top of food cost. Regulatory pressure around single-use plastics has accelerated the shift to biodegradable alternatives, which carry a 30–40% cost premium over conventional materials.

Contribution margin: what the P&L was not designed to show you

Contribution margin is revenue minus all truly variable costs: those that change directly with each unit sold. In FMCG, the genuinely variable costs per order are raw materials, direct packaging, and the platform commission on that transaction. Everything else, rent, manager salaries, utilities, central team costs, is fixed or semi-fixed overhead that must be recovered from the aggregate contribution of all transactions.

A 66% gross margin collapses to approximately 10% EBITDA and then to roughly 5% monthly cash, after debt servicing and working capital timing. The roughly 60-percentage-point gap between gross margin and cash is where the FMCG business actually lives. Burger Singh’s FY24 filing shows this in real terms: strong revenue growth and brand recognition still produced a deeply negative EBITDA because total cost growth outpaced revenue growth across every line.

When negative contribution destroys value at scale

One of the more dangerous dynamics in the delivery model is running at a negative contribution margin on specific promotions, without knowing it. When a platform discount deal (where the brand co-funds the discount) results in less net revenue per order than the sum of raw materials, packaging, and commission, every additional order in that campaign destroys value. This happens whenever discount co-funding commitments are signed without an order-level cost model, which in practice is often absent. The commission agreement and the discount agreement are signed at different times, with different teams, and their interaction is not always stress-tested before go-live.

Wastage: the cost that lives in no P&L

In most FMCG financial models, wastage is folded into raw material cost as a vague yield-loss assumption. In a real kitchen, it has multiple distinct forms, each with a different cause and a different remedy.

1. Procurement Wastage

When demand forecasting is inaccurate, fresh produce ordered for 200 covers on a Tuesday that sees only 120 has nowhere to go, and without systematic demand planning, procurement wastage of 4 to 8 percent of total raw material spend is common in Indian restaurant operations.

1. Preparation Yield Loss

The gap between raw ingredient weight and usable yield after prep. Chicken that loses 30% in trimming; vegetables that lose 20% after peeling. When recipes are costed on raw weights rather than usable yields, food cost is systematically understated from the first calculation.

1. Portion Inconsistency

A chef who portions a biryani at 350g instead of the standardised 300g is giving away 17% more food cost on every plate. At 500 orders a day, this is a daily loss that never shows up in a P&L, only in a physical stock audit.

1. Expiry and Shelf Life Loss

Processed and semi-processed ingredients that exceed their usable life. More common in multi-outlet brands with centralised commissary supply chains, where production cycles may not match outlet-level demand.

1. Pilferage

Inventory leakage is a recurring and often underreported cost in kitchens without robust stock controls, and the India food services sector overview drawing on NRAI data notes that the largely unorganised nature of kitchen operations makes this difficult to quantify and harder still to prevent at scale.

When all wastage categories are measured through physical inventory audits, the aggregate impact typically runs between 6 and 12% of raw material spend, an additional 2 to 4 percentage points of effective food cost that was never in the original model.

Working capital: the gap between the P&L and the bank account

Even a genuinely profitable FMCG business can face a cash crisis. The cause is the working capital cycle: the difference in timing between paying costs and collecting revenue. In a traditional dine-in format, cash arrives the same day it is earned. In a delivery-heavy format, vendors are paid quickly, staff are paid monthly, but platform settlements arrive 30 to 45 days after the order was placed.

A brand doing ₹20 lakh in monthly delivery GMV may have ₹6–9 lakh of cash perpetually locked in platform receivables. When that brand scales from ₹20 lakh to ₹50 lakh in monthly GMV, it grows its locked receivables in proportion. Growth consumes cash even when the business is generating operating profit.

What this looks like in a real business, with real numbers

In FY2024, Burger Singh filed financials that showed two things simultaneously: revenues of ₹77.7 crore, up 34% year-on-year, and losses that had surged 6.3 times to ₹27.9 crore. The EBITDA margin came in at -30.94%, meaning that for every rupee the business earned, it spent ₹1.17.

Burger Singh is a QSR chain backed by Rukam Capital, built around an Indianised burger format with a growing franchise footprint across 65 cities. The brand is real, the demand is real, the growth in revenue is real. The problem was that total costs grew at 43.7%, outpacing revenue by a wide margin at every line. Procurement alone, meaning raw materials, accounted for 43% of total costs and grew 31.3% to ₹39.2 crore. Employee costs rose 54% to ₹18.37 crore, and corporate overhead, commissions, and advertising pushed total expenditure to ₹91.1 crore against ₹77.7 crore in revenue.

None of this is visible in a gross margin number. Gross margin, had it been reported in isolation, would have looked reasonable: the product works, the kitchen runs efficiently, the raw material cost is not out of line. The problem was everything downstream of that line: labour scaling faster than revenue, the costs of running a centralised supply chain across a multi-city franchise network, the corporate overhead that precedes revenue at each new location, and a working capital cycle that widened as the brand scaled.

This is not a story about a failing business. Burger Singh has brand presence, a loyal customer base, and a franchise model that is structurally sound. It is a story about the cost of growing quickly in a sector where cost structures are semi-fixed and the gap between top-line growth and cash generation is structurally wider than in almost any other category. The same dynamics, labour intensity, rent overhang, platform commission, working capital timing, are present in virtually every FMCG business at scale. Burger Singh’s RoC filing makes those dynamics legible in a way that most private company financials do not.

What an investor actually looks at, and what they should

Gross margin is typically the first number a founder presents. It is also the least predictive of long-term business health. The metrics that more reliably indicate whether an FMCG brand will sustain and scale are:

1. Outlet-level EBITDA margin

Profitability of each individual outlet after all costs, including rent, labour, and overheads allocated to that outlet, but before central costs and depreciation. A well-run QSR outlet in India should generate 12–18% outlet-level EBITDA. When this falls below 8%, there is either a ramp-up issue or a structural cost problem. Burger Singh’s corporate EBITDA of -30.94% in FY24 reflects the cost of fast-scaling a franchise network: corporate overhead, ramp costs across new outlets, and centralised supply chain costs that precede revenue at each new location.

2. Contribution margin per order

Outlet-level EBITDA is the most granular profitability metric available in food and beverage. When investors see strong gross margins alongside declining per-order contribution, it signals rising platform commission intensity, unsustainable discount co-funding, or packaging cost inflation that has not been passed through in pricing.

3. Cash conversion cycle

How long does it take for a rupee spent on inventory and labour to return as cash? For delivery-heavy formats, a 30–45 day cycle is structurally unavoidable, which means working capital requirements must be explicitly sized and funded before growth, not discovered mid-scale.

4. Revenue per square foot

Two cloud kitchens showing identical gross margins can have dramatically different unit economics depending on revenue intensity per square foot, because their fixed cost absorption profiles are entirely different.

The margin that matters is the one that actually turns into cash

There is something almost hopeful about a 65% gross margin on a restaurant P&L. It suggests sixty-five of every hundred rupees is available for everything else. But the operating reality of FMCG is that “everything else” is an enormous, often underestimated, and frequently growing list: fixed costs that do not flex, variable costs that surprise, and timing mismatches that convert profitable months into cash-constrained ones.

The brands that survive the first three years and build meaningful scale are not the ones with the highest gross margins. They are the ones whose operators understood early which margin number was the real one, and built their structures accordingly. That means tracking contribution margin at the SKU level before committing to platform promotions. Auditing wastage physically rather than assuming it. Understanding working capital implications before signing a lease that assumes delivery-funded growth.

The numbers that matter in this sector, contribution margin per order, outlet-level EBITDA, cash conversion cycle, are rarely the ones that lead a pitch or a monthly review. They are harder to calculate, less flattering, and more revealing. That is precisely why they matter more than the gross margin figure that leads most pitch decks. The question for every FMCG brand, and every investor evaluating one, is whether the team running it is looking at the right ones.
