ROI calculator
What the manual way costs, worked out from four numbers the visitor can change.
What it is for
Showing a business buyer what the way they work now is costing them, before they have to ask a colleague for money. Four answers — how many people, how many hours a week, what an hour of their time costs, which plan they would be on — and the widget works out the year. It is the argument somebody would have had to build themselves, built on your page instead.
Where the numbers come from
You set what it opens on and the visitor overwrites it. This one starts at twenty-five people losing four hours a week, because a calculator showing nothing until somebody fills it in reads as broken rather than as waiting. It counts forty-five working weeks rather than fifty-two, and that assumption is printed beside the result rather than buried in the formula, since it is the one most likely to be argued with.
When not to use one
Not if it can only ever flatter you. This preset takes your own price back off the saving and says so plainly when the answer comes out negative, and a version that cannot do that is a figure nobody believes twice. Not, either, when the saving turns on something four questions cannot ask about. A number built from the wrong four is still a number, and somebody will quote it back at you.
Questions
- Can I change the figures it opens on?
- Yes. Every starting answer is a field you can rename, re-bound or remove, so what a visitor meets first is whatever you decided is typical of your customers rather than of ours.
- Does it take our own price off the saving?
- Yes. The gross figure and the net one sit beside each other, and a line appears underneath when the plan would cost more than the time it gives back.
- Why forty-five weeks and not fifty-two?
- Because nobody works fifty-two. Holiday, public holidays and the week everyone is ill come off first. Forty-five is the conservative round number, it is in the formula, and anybody who disagrees can change it.
- Do the figures somebody enters reach you?
- Only the ones they choose to send. The working out happens in their own browser, so a visitor who moves the numbers about and then leaves has left nothing behind at all.
