The Replace-It Calculator

What's that manual job or monthly subscription really costing you?

Quick answer

The Replace-It Calculator works out what a manual process or software subscription costs a year, counting both staff time and licence fees, and shows how much you could spend replacing it and still come out ahead.

Name the thing that's eating your time or your budget. See what it costs you a year, and exactly how much you could spend replacing it and still come out ahead.

What it costs you now
Most things cost you twice: the time your team spends on it and any software you're paying for. Put in whatever applies, you can leave one at zero.

Licences for the replacement
The bit most people get wrong, and it can swing the whole answer. It depends entirely on what the app connects to:

• If it only uses standard Microsoft connectors (SharePoint, Outlook, Excel, Teams) and your team already has Microsoft 365, the licence cost is usually £0, it's covered by what you already pay.
• If it needs premium features (Dataverse, SQL, custom connectors), every person who uses the app needs a paid Power Apps licence on top. Microsoft’s UK list price for Power Apps Premium was £15.40 per user a month before VAT when checked on 8 October 2026. Microsoft 365 E5 does not include it.

Either way, you only licence the people who use the app, not your whole company. Put in whatever applies, set it to £0 if you're confident it's standard connectors only.

What you could spend replacing it

Here's the honest maths. At each build price below, this is what you'd save (or lose) over 3 years, with the licences counted in. The dashed line is your break-even, spend below it and you're ahead.

Want to know what yours would actually cost?

This is exactly what I do, replace the manual graft or the monthly subscription with one thing that fits, and stop the bleed. Tell me what you're wrestling with and I'll give you a straight figure.

A rough estimate, not a quote. Real numbers depend on your actual setup. Nothing you enter leaves your browser unless you choose to send the email form.

Assumptions and limits

  • The current cost is hours a week × hourly cost × 52, plus the monthly software fee × 12. It assumes a replacement removes all of that time, which is rarely true in full.
  • The comparison runs over three years and counts only the build price and the licences you enter. Support, hosting, training and changes later are not included.
  • The build prices on the ladder are round numbers for comparison, not quotes.
