Food waste
FAO, ReFED and WRAP datasets place full-service restaurant waste at 4–10% of food purchases. We use 4.5% — the conservative floor for managed GCC operators.

Methodology
Every multiplier on this calculator has a published source.
Because your decision deserves more than a software vendor's guess. We use the most conservative end of every published range — never the headline number.
Over-ordering + spoilage
NRA + Cornell research across 210 restaurants finds 2–4% of food purchases lost to over-stock, spoilage, and unverified deliveries. We take the 3% midpoint.
Portion drift
Susskind & Reynolds (Cornell Hospitality Quarterly) measured a 2.2% mean drift between standard recipe and what actually plates, across 522 dinner services.
Admin labour rate
GCC operations manager fully-loaded cost — salary + housing + bonus + EOSB. Sources: Toast operator surveys + McKinsey 2024 hospitality margin study.
ZATCA risk (KSA only)
Based on the published ZATCA penalty schedule and 2024 audit-rate disclosures. Risk-adjusted expected loss = 1.8% of revenue for a non-compliant operator.
Sub-optimal menu mix
The Kasavana–Smith menu engineering matrix (1982, updated by Cornell 2020) shows margin × popularity re-engineering lifts revenue 1.2–2.4%. We use the floor.
Worldwide proof
These numbers actually happened — in named, public kitchens.
IKEA Food × Winnow
50% kitchen-waste reduction across 23 restaurants
After installing AI waste-measurement, IKEA Food halved kitchen waste and publicly reported diverting 4 million meals from bin. Published case, 2019–2021.

Sceptical? Good.
The most reasonable doubts people raise.
Why 70% recovery, not 100%?
Because humans run kitchens. Even with great software, 30% of bleed survives — judgement calls, staff disputes, human error. The 70% number is what our 500+ GCC field data shows AND the conservative floor in Champions 12.3 research.
Why are your multipliers lower than typical marketing claims?
Because we have to convince an operator, not a journalist. We always take the floor of the published range. ReFED says 4–10%? We use 4.5%. Our job is to under-promise the calculator and over-deliver the reality.
Do the numbers adjust by restaurant type?
Yes. Cloud kitchens and QSR run at lower waste multipliers (×0.7); fine dining and catering run higher (×1.3) due to more expensive inputs and more complex prep. The figures above are for casual dining — our default.
Can I see the full formula?
Yes. The full model — including every multiplier and unit-test — is open-sourced on GitHub. Transparency our competitors do not offer.
What if my real numbers turn out different?
The 90-day guarantee covers you. If you don't recover more than Polaris costs within 90 days, we refund 100%. So if the calculator promises AED 300K and you only realise AED 50K — we lose, not you.
The numbers are in front of you. The decision is yours.
