Camera-AI on the shop floor pays for itself when the idle machine-hours it helps you win back, valued at what a machine-hour is worth to you, add up to more than the monthly subscription, and the surplus repays the cameras and installation fast enough. With this calculator's defaults (20 machines, 15 minutes recovered per machine a day, ₹900 an hour, a ₹1.55 lakh one-time cost and a ₹24,000 monthly subscription), the gain is ₹1,12,500 a month, the net after subscription is ₹88,500, payback takes 1.8 months, and the 3-year net is ₹30.31 lakh. Every one of those inputs is an assumption. Replace them with your own figures and the quotes you actually have.

How the calculator works

The calculator takes six inputs:

  • Machines the cameras watch. Only the machines in the camera view whose stops you would act on, not every machine in the plant.
  • Idle hours recovered per machine per day. The idle time you expect to win back once stops are seen in minutes instead of at the end of the shift. 0.25 h is 15 minutes. This is your estimate, and it is the input that moves the result most.
  • Value of a machine-hour (₹/h). Your machine hour rate. The machine hour rate calculator shows how to build one.
  • Working days a year.
  • One-time cost (₹). Cameras, cabling, switch, recorder and installation: whatever you pay once. If the cameras are already installed, enter only what you add.
  • Monthly subscription (₹/month). The recurring fee for the AI layer from the quote in front of you.

The formulas:

Machine-hours recovered a month = machines × recovered hours per machine per day × working days ÷ 12
Gain a month = recovered machine-hours a month × machine-hour value
Net gain a month = gain a month − subscription
Payback (months) = one-time cost ÷ net gain a month (shown as "never" if the net is zero or negative)
Net over 3 years = net gain a month × 36 − one-time cost
Break-even recovery (minutes per machine a day) = (one-time cost + subscription × 36) ÷ (machines × machine-hour value × working days × 3) × 60

The break-even row answers the question an owner should ask first: how many minutes a day each machine has to win back for the system to pay off over three years.

Worked example (India)

A 20-machine CNC and press shop. All values are assumptions for illustration, and they are the calculator's defaults. The two cost lines are taken from the indicative 16-camera build on our page what a factory camera + AI system costs in India: about ₹1.55 lakh for hardware and installation, and about ₹24,000 a month for the AI layer (16 cameras × about ₹1,500 per camera per month). Those are planning figures, GST extra, not a price list. Use your quotes.

Input Value Basis
Machines the cameras watch 20 assumption
Idle hours recovered per machine per day 0.25 h (15 min) assumption
Value of a machine-hour ₹900/h assumption; build your own with the machine hour rate calculator
Working days a year 300 assumption
One-time cost: cameras and installation ₹1,55,000 assume; indicative 16-camera build from our system cost page
Monthly subscription for the AI layer ₹24,000 assume; 16 cameras × ~₹1,500, from the same page
Machine-hours recovered a month 125 h 20 × 0.25 × 300 ÷ 12
Gain a month ₹1,12,500 125 × ₹900
Net gain a month ₹88,500 ₹1,12,500 − ₹24,000
Payback 1.8 months ₹1,55,000 ÷ ₹88,500
Net over 3 years ₹30.31 lakh ₹88,500 × 36 − ₹1,55,000
Break-even recovery 3.8 min per machine a day (₹1,55,000 + ₹24,000 × 36) ÷ (20 × ₹900 × 300 × 3) × 60

The result is sensitive to the recovered time. Holding everything else at the defaults:

Recovered per machine a day Gain a month Net a month Payback Net over 3 years
about 3.8 min (break-even) about ₹28,300 about ₹4,300 36 months about ₹0
5 min ₹37,500 ₹13,500 11.5 months ₹3.31 lakh
15 min ₹1,12,500 ₹88,500 1.8 months ₹30.31 lakh
30 min ₹2,25,000 ₹2,01,000 0.8 months ₹70.81 lakh

Read the table from the top. If you cannot name where 4 minutes per machine a day would come from (a setter who arrives sooner, material staged before the machine runs dry, a breakdown escalated within the hour), the system does not pay on these costs. If you can name 15 minutes, the case rests on whether those minutes turn into output you sell.

What typical numbers look like

  • Indian plants have idle capacity on average. RBI's Order Books, Inventories and Capacity Utilisation Survey, released on 7 October 2026, puts aggregate manufacturing capacity utilisation at 74.6% in April–June 2026. That is a voluntary survey of manufacturing companies (994 responded on capacity utilisation this round), not a machine-level figure, but it means about a quarter of capacity sat unused on average.
  • Recovered minutes per machine. We found no credible public benchmark for how much idle time camera monitoring recovers in Indian factories. Measure your own idle hours first: the downtime calculator and the guide to measuring the cost of factory downtime show how.
  • Camera and subscription costs. Quotes are priced per camera, per stream, per instance or per site. Before entering the subscription, convert every quote to rupees per camera per month and a 3-year total; how factory video analytics is priced in India walks through the comparison.

What this number does not tell you

  • Whether a recovered hour becomes money. A machine-hour won back is worth its rate only if it turns into output you sell or into overtime you no longer pay. On a machine that is not the bottleneck, or in a month with thin orders, it is worth close to nothing. See machine hour rate: count the hours you never sold.
  • Whether anyone acts on what the cameras show. Seeing a stop earlier saves nothing unless a supervisor or setter responds. The recovered-time input should reflect what your team will actually do, not what the system can see.
  • Other levers. Guard posts, theft and an unlocked night shift are left out on purpose. If they apply at your plant, does camera-AI pay for itself in an Indian factory? sets them out, and the guard ROI calculator prices the guard lever.
  • Tax and finance. Enter both costs on the same basis, with or without GST. If you claim input tax credit, ex-GST is right; see GST, input tax credit and depreciation on factory CCTV. The calculator ignores depreciation, interest and maintenance contracts.
  • What a camera can and cannot see. A camera shows whether a machine is running, stopped or waiting with nobody at it, and for how long. It cannot see why a job was late from stores or whether a part is within tolerance. Mama looks at machines and stoppages, not at individual workers; put up a clear worker CCTV notice under DPDP before cameras go live on the floor.

FAQ

How do you calculate the payback of camera-AI in a factory? Multiply the machines by the idle hours recovered per machine a day, the working days and the machine-hour value, and divide by 12 to get the gain a month. Subtract the monthly subscription, then divide the one-time cost by what is left. With 20 machines, 15 minutes a day, ₹900 an hour and 300 days, the gain is ₹1,12,500 a month; after a ₹24,000 subscription the net is ₹88,500, and a ₹1.55 lakh one-time cost pays back in 1.8 months.

How much idle time does camera-AI need to recover to break even? On the defaults, about 3.8 minutes per machine per working day covers the one-time cost and three years of subscription. The break-even rises if you watch fewer machines, your machine-hour value is lower or the subscription is higher, so check it with your own figures.

Should I use the machine hour rate as the value of a recovered hour? Only if the recovered hour turns into output you sell or overtime you stop paying. On a machine that waits for orders or for the bottleneck, a recovered hour is worth little, so enter a lower value or count only the bottleneck machines.

Do I need new cameras to use camera-AI? Not always. Many AI layers work on existing IP cameras; in that case, enter only what you add as the one-time cost. Check stream compatibility first in adding AI to the CCTV you already own.
