A common 'rule of thumb' is to allocate around 10% of the
total project budget to evaluation costs. The cost percentage may be
higher for complex evaluations using a raft of data collection techniques
and with a heavy reliance on outside consultants. Alternatively, the
cost percentage may be lower than 10% if the evaluation is quite modest,
with only internal staff involved, and if some of the overhead costs
are born by the school/faculty.

You can download a Budget/Costings
Worksheet [Word] for calculating your estimated costs. As you
make various planning decisions you can enter their estimated costs
and so monitor likely expenditure against budget.
