MSP ROI calculator

Quantify the real cost of your current MSP relationship, including hidden licensing waste. Output is a board-ready summary, not a sales pitch.

Published 10 Oct 2025

What this tool does

Most MSP invoices are larger than they need to be, not because the MSP is dishonest, but because the contract structure rewards growth in device counts and licensing volume rather than business outcomes. This calculator surfaces the gap.

Why it matters

From 15+ years of engagement data, the average mid-market organisation can reduce MSP spend by 15-25% without reducing the service they actually rely on[1]. The calculator is the first 15 minutes of that conversation.

Inside the tool

What it includes

  • Per-device pricing inflation check (printers, switches, thin clients quietly billed)
  • Licensing utilisation audit (paid seats vs active users)
  • Out-of-scope hour analysis across a 12-month window
  • Comparison against the 15-25% typical optimisation finding from BTSL engagements

How to use it

  1. Enter your monthly MSP invoice total and managed device count
  2. Add your software licence stack and reported seat counts
  3. Provide ticket data for the last 12 months if available
  4. Receive a printable board-ready summary with prioritised actions
