Depending on the measure used, £500 in 1563 could equate to either £98,300 (using the retail price index) or £1,320,000 (using the average earnings index). A prosperous member of the gentry might expect an annual income of at least £500 during the period, with a wealthy knight like William Darrell, owning 25 manors, enjoying an annual income of around £2000.[94] ↑ It is difficult to accurately compare 16th century and modern prices or incomes.
