The 30-second answer
A typical SMB swapping between 4 and 15 A4 signs a month pays off the digital screen in 3 to 9 months. From then on it saves £10 to £70 a month in printing, lamination and manager time — plus an amount that's hard to quantify but real in sustainability and agility.
So you see the actual figures, we calculate three typical scenarios. The assumptions are listed at the bottom of the page — if your print cost or hardware price differ, you can re-run the maths.
Café 1 screen
Hannah · The Sunrise Bakery Bristol · 4 A4 changes/month
Clinic 3 screens
Sarah · Greenfield Medical Centre Manchester · 15 A4 changes/month
Chain 10 screens
5-site franchise · 100 A4 changes/month total
Honest reading: the 3 scenarios use Digisini as reference (£9 Starter, £19 Pro, £199 Network) and assume a new £250 Smart TV + £40 Fire Stick. If your current TV runs Android TV or webOS, you save the £40 Fire Stick. If the TV already exists in the venue (very common in cafés and offices), year 1 hardware drops to £40 and payback shifts to 3-4 months in scenario 1.
The five variables that feed the calculation
ROI isn't magic. It comes from comparing what you spend today on printed signs with what you'd pay tomorrow on digital signs. The five numbers that matter:
| Variable | Reference value | Notes |
|---|---|---|
| Colour A4 print + lamination | £0.25-£0.45 | Typical UK print shop. In-house plotter ends up similar once you count ink + time. |
| Ink cartridges | £25-£40 each | A typical SMB uses 2-4 cartridges a year on signage. |
| Hour of design and manual plotter work | £15/h × 1-2 h/month | Manager or owner's time. It's not just cost — it's opportunity cost. |
| Hardware (Smart TV + Fire Stick) | £250 + £40 = £290 | £0 if you reuse an existing TV. A 700-nit commercial panel pushes this to £800-£1,500. |
| Digisini cloud software | £9-€199/mo | Starter £9, Pro £19, Business £59, Network £199. Free with watermark to test. |
How the math works
For one screen, year 1:
- Digital cost = One-time hardware (£290) + 12 × monthly subscription (£9 = £108) = £398
- Printed cost = Changes per month × 12 × cost per change (print + hours + amortised cartridge). For 4 changes/mo at £6.50/change (including time) = £312/year
Year 1 digital is slightly more expensive (hardware weighs). From year 2 on you only pay software, and the gap stacks in your favour every month.
5-year projection: when the saving shows up
The real return on digital signage shows in the 3-5 year TCO (Total Cost of Ownership), not in the first month. Here's the projection of the 3 scenarios:
| Scenario | Year 1 | Year 3 | Year 5 | 5-year saving |
|---|---|---|---|---|
| 1 · Café | +£86 | −£220 | −£940 | £940 |
| 2 · Clinic 3 screens | −£342 | −£2,166 | −£5,310 | £5,310 |
| 3 · Chain 10 screens | −£4,552 | −£17,304 | −£32,760 | £32,760 |
Negative numbers are savings (digital costs less). Only scenario 1 (café with 4 changes a month) has a slightly negative year 1 because hardware weighs more than the initial saving. From year 2 on it's all net gain.

Some variables are hard to put in pounds but they're real. We mention them so the calculation stays honest:
Extra sales from agility
A café that changes the daily special from their phone at 11 AM (because the chef just told them the cod is gone) probably sells 3-5 extra dishes by direct substitution. A printed sign would have kept showing the gone cod until someone went to change it. That doesn't enter the baseline ROI.
Night-time shop window pull
In retail, a shop-window screen keeps working after closing, catching evening walkers. Field estimates put this between 2-8% of extra attributable sales. We don't add it to the calculator because it depends on the area, but it's real.
Reduced perceived wait time
In GP surgeries and pharmacies with a waiting room, a screen rotating useful content reduces perceived wait by up to 35%. That doesn't translate directly to money but it does to satisfaction and reviews — and reviews convert.
Sustainability and CO₂ avoided
200 A4 prints avoided per year ≈ 4 kg paper + 0.8 kg plastic (laminate) + ≈ 5 kg CO₂ between production and transport. Multiply by 5 years and that's 25 kg of CO₂ per screen — useful to mention if your business has an ECO badge or sells to clients who value it.
When digital signage doesn't pay off
Honesty as criterion: there are cases where the amortised printed sign is still better. We won't sell you a screen you don't need.
- Business with fixed hours and no weekly offers: if you only change the "summer break" sign once a year, an A4 laminate at £1.50 is unbeatable.
- Venue with no wifi and no possibility to cache: cloud digital signage needs a connection at least every 48 hours to sync. In rural zones without internet, not even the best cache saves you.
- Space with no place for a TV: sounds obvious but it happens. Some small businesses have no spare vertical wall. Table-top signs or A4 prints remain the option.
- Manager or owner who won't learn the app: the cheapest tool is the one you already know. If the person operating the screen will never open the panel, a printed sign will work better than a screen no one updates.
The honest calculator: if your business changes fewer than 3 signs a month and the TV won't be in a visible shop window, you probably don't need digital signage yet. Come back when the change volume grows.
Do it yourself: 4-step template
If you want to reproduce the calc with your real numbers, follow these 4 steps:
- Count the changes per month: how many times a month you change or reprint signage. Be honest, add the small ones (prices, hours, events).
- Calculate cost per change: print + lamination + time. In the UK it's typically £5-£8 per change at a print shop and £3-£5 in-house with a plotter.
- Multiply by 12 months: that's your annual printed-signage cost.
- Compare with the plan you need: £9 Starter for 1 screen, £19 Pro for 3 screens with advanced scheduling, £199 Network for up to 50 screens multi-site. Add year 1 hardware (£40-£290).
If your annual printed cost is higher than total digital year 1 cost, payback already lands before month 12. If it's 2× in favour of digital, payback lands in 6 months. If 3×, in 4 months.
