Should You Hire or Automate?
Before you sign a contract of employment, run the numbers. Compare the true cost of hiring against automating the same work and find out which option makes more financial sense for your business.
A £35k hire typically costs employers over
£43,000
in year one
Well-scoped automations typically pay back in
3 to 6 months
Up to
75%
of admin tasks in service businesses can be automated
When your business hits a capacity wall, the first instinct is to hire. But for service businesses with admin-heavy workflows, automation often covers the same ground at a fraction of the cost. This calculator shows you the true financial comparison: what hiring actually costs once you factor in employer taxes, pension, and recruitment, versus what automation would cost to build and maintain over the same period.
It will not tell you which is right for your business. It will tell you what the numbers look like before you decide.

The true cost of hiring that most businesses miss
Most business owners think about a hire in terms of the advertised salary. The actual cost is considerably higher. On top of gross salary, UK employers pay National Insurance contributions of 13.8% on earnings above the secondary threshold, a minimum 3% pension contribution under auto-enrolment, and typically 10 to 20% of first-year salary in recruitment costs through agencies or job boards.
Before the new hire produces any value, there is also onboarding time (typically two to four weeks of reduced productivity), equipment and software licences, and the management overhead of integrating someone into the team. For a role advertised at £32,000, the real first-year cost to the employer typically lands between £42,000 and £48,000.
Automation does not carry employment costs. Once built, the ongoing cost is tooling and maintenance, typically a small fraction of an ongoing salary. The upfront build cost is the trade-off, and for admin-heavy work it usually resolves within the first quarter.
When hiring is still the right answer
Automation is not a substitute for human judgment, relationship management, or specialist knowledge delivery. If the capacity gap is primarily in client-facing work, consulting, or tasks that require discretion and adaptability, hiring is the right call. Automation works best on tasks that are clearly defined, high frequency, and follow consistent steps each time.
The most effective approach for growing service businesses is usually to do both: hire for the delivery work that genuinely requires a person, and automate the admin overhead surrounding it. A well-automated business can often scale headcount more slowly than its revenue because each hire is more productive from day one, with less time lost to repetitive manual processes.
What counts as automatable work
The table below outlines common task types in service businesses and their typical automation suitability. Use it to sense-check how you categorised the work in the calculator above.
| Task type | Examples | Automation suitability |
|---|---|---|
| Data entry and formatting | CRM updates, spreadsheet population, form processing | High |
| Report generation | Monthly performance reports, financial summaries, client updates | High |
| Email and communication sequences | Follow-ups, onboarding emails, reminders, confirmations | High |
| Scheduling and coordination | Booking management, internal notifications, approval routing | Medium |
| Document creation | Proposals, contracts, invoices generated from templates | Medium |
| Client delivery and consulting | Advice, strategy, relationship management, knowledge work | Low |

No. To keep the comparison clean, the calculator uses a flat salary cost across years 1 and 3. In practice, most employees receive salary increases of 2 to 5% annually, which would push the 3-year hire cost higher than shown here. Automation costs do not change unless you upgrade the tooling or expand the scope, so the real advantage of automating typically grows over time.
