ROI Calculator
The cost of answering late.
Every enquiry goes to whoever replies first. Put your numbers in and see the revenue and hours a workforce that answers in seconds gives back.
Three numbers to have ready
- Enquiries you take a month
- Average value of a won client
- How fast you reply today
Two minutes, no email needed. The result stays on screen.
In short
The ROI calculator shows what unanswered enquiries cost you over a year, and what an Autonomous Digital Branch recovers. Enter your enquiry volume, their value, and your current response time; it estimates the leads lost to slow replies and after-hours gaps that an always-on AI workforce would capture and book instead.
Every figure here is an illustrative estimate, not a guarantee. We use conservative caps on purpose, so the number is one you could defend to a finance director. Your real result depends on your market, your offer, and how well the front of your business already runs.
The number
What a reply in seconds is worth.
Most enquiries go to whoever answers first. Put four honest numbers in and we will show the revenue and the hours you leave on the table by replying slowly.
Start with your volume.
Round figures are fine. We only need the shape of your funnel.
Calls, forms, and messages combined.
A single job, or a year of a retainer.
Worked example
The model, worked through once.
The same maths the calculator runs, on its starting values, line by line. This is an illustrative example of the model, not a quote or a promise; put your own numbers in above and the figures change with them.

Why the number is rarely small
A slow reply is not a small problem. It is the problem.
The lead you lose to a faster competitor cost the same to generate as the one you win. You paid for the advert, the referral, the reputation. The only difference was who answered first.
Sources: Drift Lead Response Report (2017), Harvard Business Review / MIT lead-response study (2011), and Silverfin All Accounted For (2025). These are published benchmarks, not results we are attributing to a single client.
55%
of firms reply in over five days, or never
In an audit of 433 B2B companies, 55% took more than five working days to reply to a web enquiry, or never replied at all (Drift Lead Response Report, 2017). By then the prospect has called someone else.
21x
more likely to qualify a lead in five minutes
Reply within five minutes and you are up to 21 times more likely to qualify the enquiry than a firm that waits thirty minutes (Harvard Business Review / MIT lead-response study, 2011). After business hours, the gap is a chasm.
£48k
lost per accountant each year to admin
UK accountants lose nearly £48,000 each in potential earnings every year to admin and outdated systems (Silverfin, All Accounted For, 2025). Most of it is invisible until you count it.
Reading your number
What your result is actually telling you.
Three figures come out the other side. Together, they are the gap between the business you run today and one that answers every enquiry, every hour, without another hire.
Extra revenue a year
The deals you would win if every enquiry were answered and qualified on the spot, instead of leaking to whoever replied first.
Hours handed back
The time your people currently spend answering, qualifying, and chasing by hand, freed for the work only a human should do.
The conversion you are leaving
The lift from your current win rate to what a branch that never sleeps and never forgets a follow-up can hold.
Built to be defensible
We cap the recovery and the conversion deliberately. The number you see is one you can put in front of a finance director without flinching.
Questions
The calculator, answered.
It takes four numbers from you: monthly enquiry volume, average value of a won client, how fast you reply today, and your current win rate. It then models the share of would-be conversions lost to a slow first response, and recovers part of that loss, capped at 45 percent of it, so the result stays honest rather than flattering. Conversion is never allowed past 95 percent.
It is an estimate, and we say so on the result. The figures show the shape of the opportunity, not a promise. We use conservative caps precisely so the number is one you can defend to a finance director. Your real outcome depends on your market, your offer, and how well the front of your business already runs.
Most enquiries go to whoever answers first. The Harvard Business Review / MIT lead-response study (2011) found firms that reply within five minutes are up to 21 times more likely to qualify a lead than those that wait thirty minutes, and the odds fall sharply after the first few minutes. An Autonomous Digital Branch answers and qualifies in moments, day or night, so fewer leads slip to a faster competitor.
No. The headline figure, the extra revenue and the hours saved, appears on screen as you work through the steps. You only share your details if you want us to send the breakdown and come back with a branch scoped to capture it.
