Put a number on what every week of delay is really costing your programme. It is almost always more than people think.
Why this matters. When a programme slips, the conversation is almost always about the extra cost of running it for longer. That is the smaller number. The bigger one, and the one that rarely makes it onto a slide, is the value you are not yet getting because the benefits have not landed. A programme worth two million a year in savings that slips six months has quietly cost a million pounds, before a penny of extra spend.
This calculator makes that hidden number visible, so delay can be weighed honestly against the cost of fixing whatever is holding the programme up.
The yearly benefit when it is working: revenue gained, cost saved, or cost avoided. A best estimate is fine.
How long the programme has slipped, or how long you expect it to slip.
Roughly what it costs to keep the programme running each month, team, suppliers, licences. Leave blank if you are not sure.
Please enter at least the annual value and the delay in months.
A number like this usually means something specific has stalled, scope, data, a decision that is not being taken, a supplier that is not performing. Christopher Fagan has recovered some of the largest transformation programmes in the UK, including the BP Pulse rollout across five countries. A short, confidential conversation will help you find what is actually holding yours up.
Talk to Christopher FaganThis is a deliberately simple model. It counts the benefit you postpone plus the cost of running longer, which is the honest core of cost of delay. It does not try to model compounding, lost market position or team morale, all of which usually make the real figure larger, not smaller.
