Capacity, leave administration cost and payroll readiness are all things teams estimate by feel, usually optimistically, and the gap between the feel and the arithmetic is consistently large.
These do that arithmetic. Two of the four will produce a number bigger than you expect, which is the point of running them. None of them asks for an email, and the arithmetic runs in your browser rather than on our servers.
Your figures, our arithmetic, shown. No address required to see a number.
The capacity calculator and the leave admin cost calculator both measure the same thing from different ends: time that exists on paper and does not exist in practice.
Most teams find available capacity is fifteen to twenty-five per cent below the headcount figure they had been planning against, and that non-project time is roughly double their guess.
The payroll readiness checklist is the one to work through slowly. It is ordered deliberately, and the edge cases at the end are where first pay runs actually break.
Every tool here runs on your figures, shows its arithmetic, and lets you leave with the result. None of them ask for an address before showing a number.
See the Nest journeys →If you are planning delivery, run the capacity calculator first and be honest about non-project time. It is the input everybody rounds down.
If you are moving payroll, work through the readiness checklist before you agree a go-live date rather than after.
Balances, entitlement and the accrual rule per employee. A CSV from your current HR system or payroll provider is enough.
It asks for them explicitly rather than assuming a national rate, because employer contributions are the part people underestimate.
Yes. They read the same figures your provider already reports back to you; none of them need access to a payroll system.
No. Everything runs in your browser on figures you type in. Nothing about a named person needs to be entered at all.
No. They are arithmetic on your own headcount and hours, and are most useful while you are still deciding.
Tell us what you were trying to work out. Half of these exist because somebody asked for them.
