The fifth grant is calculated slightly differently from the fourth SEISS grant.
People who have seen a drop in turnover of 30 percent or more will be entitled to a grant worth 80 percent of average monthly trading profits, capped at £7,500.
However for people whose turnover has not decreased by 30 percent or above, the fifth grant will be worth less than this.
In this case, the fifth grant will be worth 30 percent of average monthly trading profits, capped at £2,850 for the three-month period.
Rishi Sunak told MPs in his Budget announcement: “People whose turnover has fallen by less than 30 percent will therefore have less need of taxpayer support and will receive a 30 per cent grant.”
