How to cost internal staff time on an event
Your team spends hours on the event every week, and none of it appears in the budget the committee sees.
The short answer
Estimate internal labour as hours per role, multiplied by a loaded hourly cost supplied by your finance team. Show it on a separate line below the cash budget, labelled as internal cost, not as money to be paid out.
The purpose is visibility. The committee can then see what the event really takes and decide whether to fund the time, protect it, or buy outside help for part of it.
Decide why you are costing time
- To show the full cost of the event to a committee or board.
- To compare in-house delivery with appointing outside help.
- To protect staff capacity by agreeing hours with their managers.
- To satisfy a funder's request, if one exists, for staff contribution. Ask the funder for its rules rather than assuming them.
Build the estimate from tasks, not from titles
- List workstreams: programme, speakers, registration, suppliers, communications, finance, on-site.
- For each, list the people involved and estimate hours across the project, with a low and a high figure.
- Ask each person's manager to confirm the hours are realistic alongside their normal work.
- Ask finance for the hourly cost to use, and what it includes. Do not invent a rate or use a figure from a different organisation.
- Multiply and total by workstream. Enter the result in the budget builder as an internal cost category, separate from cash.
Staff, volunteers and committee members
| Group | How to record | Question to ask |
|---|---|---|
| Salaried staff | Hours multiplied by finance's loaded hourly cost. | Is any of this time already charged to another budget? |
| Volunteers and committee | Record hours as a note, or value them as in-kind only if your finance contact agrees (see in-kind valuation). | Is there any expense or honorarium being paid? |
| Temporary or contract staff | Treat as cash cost from the contract. | Is the cost already in a supplier quotation? |
| Overtime or time off in lieu | Record separately and check with HR. | What does your policy say, and who approves? |
Using the number
Show cash budget, internal labour and total effort as three separate lines. Do not add internal labour into the cash total that finance will pay.
If hours exceed what managers can release, the committee has a choice: reduce scope, extend the timeline, or bring in outside support for named workstreams. See cost reduction trade-offs for how to frame the options.
Worked example · Fictional example
Internal labour for a regional forum
Fictional organisation and figures. The hourly cost is a round number the fictional finance team supplied for arithmetic, not a market rate.
A fictional corporate communications team plans a forum. Finance supplies a loaded hourly cost of RM 50 for all staff to keep the example simple. The estimate is 420 hours in total.
The internal labour line shows RM 21,000, below the cash budget of RM 60,000. The committee sees that two staff members would be at 40 per cent of their time on the event for three months and asks their manager to confirm.
| Workstream | People | Hours | Hourly cost (from finance) | Internal cost |
|---|---|---|---|---|
| Programme and speakers | 2 | 140 | RM 50 | RM 7,000 |
| Registration and communications | 2 | 120 | RM 50 | RM 6,000 |
| Suppliers and finance | 1 | 80 | RM 50 | RM 4,000 |
| On-site coordination | 3 | 80 | RM 50 | RM 4,000 |
| Total | 420 | RM 21,000 |

Handle it in-house, or bring in help?
Your team can usually handle this when
- Finance provides a standard hourly cost and your managers can confirm hours quickly.
- The purpose is visibility for the committee, not billing.
- The team is small and workstreams are easy to list.
Outside planning help earns its fee when
- Hours are estimated from titles rather than tasks and nobody can say what the team will stop doing.
- The estimate shows the team is over capacity and outside support for named workstreams must be scoped.
- Several departments contribute staff and the allocation needs a neutral overview.
Is your team's time larger than the plan shows?
An Event Blueprint can map workstreams to roles and hours, so the committee sees which tasks the team keeps and which could go to a temporary embedded event manager for a set period. Finance still supplies the hourly cost and your managers confirm the time released.
Questions organisers ask
What hourly cost should I use?
Ask your finance team. They know what a loaded cost includes in your organisation. This site does not supply rates.
Should internal labour be part of the event budget?
Show it on its own line, below cash. It reveals the real effort, but it is not money paid out, so it should not be added into the cash total finance must fund.
Do I cost volunteer time?
Record the hours at least as a note. Whether to put a value on them is a decision for your committee and finance contact, and it affects how the figure is read.
