What actually kills restaurants
It isn't bad food, low footfall, or aggressive competition. The dominant patterns we see in pilot data and in industry post-mortems:
- Working capital exhaustion: month 2 EMI + salaries + rent without enough revenue cushion.
- Food cost drift: opening at 30%, drifting to 38% by month 5 without realising it.
- Aggregator commission compounding: chasing orders instead of profitable orders.
- Retention collapse: opening week is great because of curiosity; week 6 is the truth.
Number 1: break even (and how often you cross it)
If you don't know your daily break even, you can't know if today was profitable. Track ‘days above break even’ in a calendar view from week one. Healthy: 22+ days/month. Tight: 18 to 21. Dying: <17.
Number 2: food cost %
Track weekly, not monthly. A 2 point drift over 4 weeks is the canary. Action: pull a recipe cost on your top 6 dishes against current mandi prices. Most drift comes from 2 to 3 dishes, fix them, not the whole menu.
Number 3: prime cost
Prime cost = food cost + total labour. Healthy Indian casual dining: 55 to 62%. QSR: 50 to 58%. Above 65% the business is structurally fragile; there is no margin left for rent + utilities + everything else. Cut labour before menu price.
Number 4: 30 day cohort retention
Of every 100 first time customers in week 1, how many came back within 30 days? Healthy: 22%+. Below 12% you have a product market problem, not a marketing problem. The most common cause: opening week menu was different from steady state menu.
