UK minimal financial assistance allowance calculator
Add the relevant assistance recorded in award letters to estimate headroom against the £315,000 MFA threshold.
Which period and awards should I include?
The applicable period is the elapsed part of the current financial year and the two preceding financial years, rather than a rolling 36-month period. Identify the correct period with the awarding authority. Consider the enterprise and other enterprises under common control, rather than only one company or project.
Not every public grant is MFA. Check each award letter's classification, any relevant SPEI or other cumulation rules and the date assistance was awarded. Avoid double-counting. Sector rules and Northern Ireland arrangements may require different treatment.
This tool performs arithmetic on the figures you enter. It cannot determine the legal classification of assistance, group boundaries, applicability of a regime or entitlement to receive an award. Confirm these with the awarding authority or a qualified adviser.

If relevant assistance totals £100,000 across the applicable period, the arithmetic headroom is £215,000. A proposed £220,000 MFA award exceeds that headroom by £5,000; this does not establish whether another subsidy route is available.
