Marketing guesstimates
Estimate demand, show your assumptions and check how sensitive the answer is. These fictional Indian scenarios use practice inputs.
Monthly office lunch orders in Pune
Estimate weekday orders from one office district. Assume 120 buildings, 250 workers each, 65% onsite, 35% ordering lunch, 20% choosing delivery, and 22 workdays.
Reveal the calculation
- 120 × 250 = 30,000 workers. Onsite workers per day = 30,000 × 65% = 19,500.
- 19,500 × 35% × 20% = 1,365 daily delivery orders.
- 1,365 × 22 = 30,030 monthly category orders. At 10% capture, your service gets about 3,003.
If delivery preference is 10–30%, category demand ranges from about 15,015 to 45,045. Validate with office occupancy and merchant order logs.
Annual mixer-grinder demand in Jaipur
Estimate replacement and first-time purchases. Assume 800,000 households, 65% ownership, a seven-year replacement cycle, and 5% annual adoption among non-owners.
Reveal the calculation
- 520,000 households own a mixer. At a stable replacement cycle, 520,000 ÷ 7 ≈ 74,286 replacements.
- 280,000 households do not own one. At 5% adoption, about 14,000 buy this year.
- The total is about 88,300 units annually. At ₹2,500 per unit, retail value is about ₹22.1 crore.
Cross-check using retailer sell-through and online delivery. Multiple devices, repairs and replacement age can change the result.
Monthly trial demand for a Bengaluru subscription
A coffee subscription serves 400 apartment complexes of 180 homes. Assume 45% drink ground coffee, 20% buy online and 5% of eligible households trial monthly.
Reveal the calculation
- 400 × 180 = 72,000 homes in the service footprint.
- 72,000 × 45% × 20% = 6,480 households meeting both criteria, assuming the online rate applies among ground-coffee drinkers.
- 6,480 × 5% = 324 trial customers per month. At ₹399 per trial, revenue is ₹1,29,276 before refunds.
Use 3–8% trial as a sensitivity range, about 194–518 customers. A pilot must verify retained contribution after delivery and CAC.
Annual B2B packaging opportunity in Surat
Estimate the addressable market for garment export cartons. Assume 600 exporters, 30% in the target segment, 4,000 cartons per month each and ₹28 per carton.
Reveal the calculation
- 600 × 30% = 180 target accounts.
- 180 × 4,000 × 12 = 86.4 lakh cartons annually.
- 86.4 lakh × ₹28 = ₹24.192 crore. If direct sales can reach 40 accounts, reachable value is ₹5.376 crore before win rate.
Separate seasonal peaks from average demand. Validate with dispatch volumes and distributor records.
Incremental coupon orders in Chennai
A grocery app reaches 100,000 eligible customers. A holdout converts at 4%, and treatment at 5%. Each incremental order contributes ₹180 before a ₹40 coupon used by 3,000 customers.
Reveal the calculation
- At 100,000 exposed customers, the baseline is 4,000 orders and treatment forecast is 5,000.
- 1,000 additional orders yield ₹1.8 lakh in contribution before coupons.
- 3,000 redemptions cost ₹1.2 lakh. Expected incremental contribution is ₹60,000 before other campaign costs.
Break-even requires about 667 incremental orders at the same redemption cost. Recheck repeat and coupon cannibalization.
Annual home water-purifier servicing in Hyderabad
Assume 1.5 million homes, 40% purifier ownership, 75% of owners service annually and 1.2 paid visits per servicing household at ₹700.
Reveal the calculation
- 1.5 million × 40% = 600,000 homes with purifiers.
- 600,000 × 75% × 1.2 = 540,000 visits per year.
- 540,000 × ₹700 = ₹37.8 crore in annual category revenue before parts.
At 60–90% annual service uptake, the estimate ranges from 432,000 to 648,000 visits. Compare with technician capacity and service-company invoices.
