# IT Support Cost Calculator > IT support cost calculator for UK businesses: 25 users at £45 per user per month plus 2 managed servers is £1,275 a month, and £17,300 in year one with onboarding. ## Key facts - On this calculator's placeholder rates, 25 users and 2 managed servers models to £1,275 a month and £15,300 a year excluding VAT, rising to £17,300 in year one once a £2,000 onboarding fee is added. - Because device charges are largely fixed, the effective cost per user per month falls as headcount rises: £60 at 5 users against £49 at 100 users on identical rates. - UK business IT support is a standard-rated supply, so VAT at 20% is added to the fee (gov.uk, 2026); VAT-registered businesses normally recover it, which is why quotes should be compared excluding VAT. ## Key pages - [IT support cost calculator: what will support cost you?](https://itsupportcostcalculator.co.uk/): the main tool, answer above the fold. - [IT support cost per user per month: how the number is built](https://itsupportcostcalculator.co.uk/it-support-cost-per-user/): Per-user pricing is the UK norm for managed IT support.

Methodology: Every row is computed with the exact expressions this page's calculator uses: monthly fee = users x (rate per user + add-ons per user) + devices x rate per device; annual = monthly x 12; VAT at the standard 20% rate (gov.uk, 2026). Inputs held constant across rows: rate per user £45/month, add-ons £0, rate per device £75/month, onboarding £0, project hours 0. Those rates are the calculator's labelled placeholder defaults, chosen so the model computes, not a surveyed market average; substitute the rates on your own quote using the tool above. - Last updated: 2026-08-14.
