Business Downtime Calculator vs Spreadsheet
Many small business owners estimate downtime cost in a spreadsheet — and that's a perfectly reasonable approach when the model already exists. WorkplaceReady's Business Downtime Cost Calculator is designed for the moment before that spreadsheet exists: it gives you a defensible first estimate in a few minutes, using the same underlying inputs an accountant would ask for.

WorkplaceReady Downtime Calculator
What it is
The Business Downtime Cost Calculator asks for a small set of business inputs (typical revenue, staff cost, recovery time, and how much activity continues during an outage) and estimates the operational and labour impact of an interruption. It is a planning tool, not an accounting tool.

What it is
A spreadsheet lets you model downtime cost exactly the way your business works — with your own formulas, categories and assumptions. It is the right long-term home for a mature estimate, especially one that has been reviewed by your accountant.
Side-by-side comparison
A quick reference for small business owners deciding which approach fits the moment.

When WorkplaceReady Downtime Calculator saves time
You need a number for a conversation this week
The calculator returns a plausible operational and labour impact estimate in a few minutes — useful for a management meeting, an insurance conversation or a supplier discussion.
You don't want to build a model from scratch
The inputs are already there, with sensible defaults you can adjust. You don't have to decide what to include or how to structure the maths.
You want to compare scenarios quickly
Change one input, re-run, compare. Faster than rebuilding a spreadsheet section for each scenario.
When Spreadsheet (DIY) is the right choice
You already have a model that works
If your accountant or operations team has a spreadsheet the business trusts, keep using it. The calculator is not designed to replace an established financial model.
You need custom categories or formulas
Some businesses need to model downtime by product line, shift, or customer tier. A spreadsheet is the right tool for that level of detail.
You need to hand the file to a third party
Auditors, lenders and advisors often prefer a file they can open, review and adapt.

Is the calculator a replacement for my accountant's spreadsheet?+
No. It's a fast, first-pass estimate designed for planning conversations. A spreadsheet reviewed by your accountant remains the right long-term home for a mature model.
How accurate is the estimate?+
It's as accurate as the inputs you provide. The calculator uses standard operational and labour cost logic and does not attempt to model tax, insurance recoveries or long-tail customer impact.
Can I save or export the result?+
You can print or screenshot the on-screen summary. For a persistent, editable record, a spreadsheet is a better fit.
Is it really free?+
Yes. The Business Downtime Cost Calculator is a free WorkplaceReady tool — no sign-up required.
