Reading the result
The calculated amount equals the entered cost multiplied by the percentage and divided by one hundred. The remaining cost is the difference. Enter the eligible expense base for the programme you are reviewing, which may differ from the invoice total.
Prepare the figures before deciding
Check eligible expenses, amount limits, dates and documentation in the programme terms. If a maximum award applies, compare that limit with the result. The calculator does not include caps, tax deductions or compatibility rules.

Frequently asked questions
Which percentage should I enter?
The percentage of the programme you are reviewing, or a value you want to compare as a scenario.
Does the result confirm a grant?
No. It is a calculation using your inputs. Award and final amount depend on the programme conditions and decision.
Can I calculate without a project cost?
Request a quote from Lumera to obtain a project reference and return to compare the amounts.
