How we calculated
- Employer NI: 15% of salary above the £5,000 secondary threshold (gov.uk, 2026/27). Employment Allowance is not applied.
- Pension: 3% of earnings between £6,240 and £50,270, above the £10,000 trigger (gov.uk, TPR).
- Days: 260 weekdays less holiday (28 days statutory) and sickness (ONS 2022: 5.7 days).
- Outcomes are a year-one monthly average: ramp-up months count at the output you set.
- Figures checked 2026-09-28.
Conversion rates
Example rates, adjust to yours. The same rates apply to both sides. Faster follow-up often lifts them, but nothing here assumes it.

ClientTurn is bounded by plan allowances. Pro without Voice covers the emails and prospects. Calls: add 1 × 100 min + 1 × 500 min (£286/month).
These are estimates from your inputs, not a quote and not financial advice. Tax figures are for 2026/27, checked 2026-09-28 (NI, pension, holiday on gov.uk; sickness from ONS). ClientTurn prices exclude VAT. An AI agent is not a like-for-like replacement for every SDR task: relationship building and complex negotiation still need a person.
Questions
Before you decide.
More than the salary. On top of pay, employers add National Insurance (15% above £5,000 in 2026/27), an auto-enrolment pension, recruitment, tools, management time and a ramp-up period. Enter your own figures above.
Not for everything. ClientTurn handles the volume work: replying fast, following up, qualifying and booking. Relationship building and complex negotiation still need a person.
No. The AI Voice Sales Agent only calls leads who asked for a call or agreed to one on your form, and says it is an AI assistant at the start of every call.
Plans start at £99 a month. Pro with the AI Voice Sales Agent is £499. Every plan has monthly allowances and no overage; Enterprise is priced per contract.
