Cost of inaction calculator
Most business owners can say what a project would be worth. Far fewer have put a number on what it costs to keep not doing it.
This page does both. Answer four questions about a project you have been meaning to finish and it returns two figures: the revenue the delay has already cost you, and what the project is worth in its first year. The numbers are yours rather than industry averages, and the method is written out in full below the calculator.
What’s inaction really costing you?

What cost of inaction means
Cost of inaction is the revenue a project would already have earned if it had been finished, counted across the time it has been sitting still. It is not a penalty and it is not a forecast. It is arithmetic on a decision you have already made: the project is worth doing, and it has not been done yet.
The figure matters because delay is the easiest cost in a business to ignore. An unfinished project appears nowhere in your accounts. There is no invoice for the launch that did not happen and no line item for the month that passed, so the cost stays invisible until somebody writes it down. Putting a number on it is what turns “I’ll get to that” into something you can weigh against the cost of getting help.
Most owners underestimate it, because the mind compares finishing the project against today rather than against the version of today in which it had been finished months ago.
How the four questions become a number
Three of the four questions shape the arithmetic. The fourth shapes the words around it. Here is exactly what each one does.
1. Which project
You pick one of four project types: launch a product or service, grow something that already works, complete a stalled project, or systemise the business so it runs without you. This choice decides which formula runs and which two figures you are asked for next.
2. Your two figures
Each project type asks for the two numbers that set its first-year value, and nothing else. There are no benchmarks or multipliers behind the scenes. Move either slider and the running total under it updates, so you can watch the formula work before you go on.
3. How long it has been sitting
You choose a range rather than an exact figure, and the calculator converts that range to its midpoint in months. That midpoint is the multiplier applied to the monthly value of the project.
4. What has been holding you back
A roadmap, focus, accountability, confidence, or all of them. This answer changes neither number. It selects the wording of the summary you get, and it is the part worth bringing to a conversation, because the block is usually the reason the arithmetic exists at all.
The four formulas
First-year value is the whole basis of the result, so here is each one in full.
| If you choose | You enter | First-year value |
|---|---|---|
| Launch a product or service | Customers per month, average sale price | customers x sale price x 12 |
| Grow what’s already working | Current monthly revenue, realistic growth target | monthly revenue x growth target x 12 |
| Complete a stalled project | Potential first-year revenue, amount already invested | potential first-year revenue |
| Systemise my business for freedom | Hours per week to reclaim, what an hour of your time is worth | hours x hourly rate x 52 |
- On a stalled project the amount already invested is shown back to you as context and is deliberately left out of the projection. It is a sunk cost, and counting it as future value would inflate the result.
- On the systemise option the first-year value is time rather than cash, priced at the rate you set. It reads as capacity reclaimed, not revenue booked.
How each stall range is counted
- 1 to 3 months: counted as 2 months
- 3 to 6 months: counted as 4.5 months
- 6 to 12 months: counted as 9 months
- 12+ months: counted as 15 months
Each range becomes its midpoint, so the estimate sits at neither the optimistic nor the pessimistic end of the answer you gave. The last band is open ended, so it is capped rather than run on indefinitely.
Cost of staying stuck = first-year value divided by 12, multiplied by the number of months. The other figure on the results screen, the project’s first-year potential, is the first-year value itself.
A worked example, start to finish
A consultant has a workshop programme built and ready to sell, and has not launched it. This is the whole calculation, in the order the calculator runs it.
- Project type
- Launch a product or service
- Average sale price
- $500
- Customers per month
- 15
- First-year value
- 15 x $500 x 12 = $90,000
- How long it has been sitting
- 6 to 12 months, counted as 9 months
- Monthly value of the project
- $90,000 divided by 12 = $7,500
- Cost of staying stuck
- $7,500 x 9 = $67,500
The results screen puts the two figures side by side: $67,500 of revenue the delay has already cost, against $90,000 available in the first year of running the programme. The blocker answer, say focus and prioritisation, changes the sentence framing them and neither total.
Under those a projection chart extends the same figure forward on a deliberately plain model: every completed project keeps earning its first-year value in each year that follows, with no compounding, no price rises and no drop-off. At 4 completed projects a year at $90,000 each, year one totals $360,000, and each following year adds the projects already running plus the new ones. The chart is the part of the tool you can steer directly: project value, projects per year and the time horizon are all adjustable, so you can pull it down to something you would stand behind.
What the number does not claim
Read both figures as the size of a gap, not as money owed to you.
- It assumes the project would have sold at the rate you gave it from the moment it was ready. Real launches ramp. For a conservative read, halve the monthly figure before you look at the total.
- It counts revenue, not profit. Delivery costs, tax and your own time are not subtracted.
- It ignores what you did instead. If those months went into other work that earned, the true net cost is lower than the figure shown.
- It does not adjust for inflation, for a price change over the period, or for a market that moved while you waited.
- The systemise option prices reclaimed time at the rate you set. That is capacity, not cash, and it converts to revenue only if you spend the hours on something that earns.
- Nothing here is a promise about what coaching would produce. The calculator measures the gap; closing it is a separate question.

What to do with the number
A cost of inaction figure is only useful sitting next to a decision. Put it beside what finishing would actually take: a deadline you have committed to, a weekly rhythm, and somebody holding you to both. If the gap is larger than the cost of getting help, you have your answer.
