As to yearly wage, none existed as such. When on campaign or in garrison, soldiers in English employ were generally paid on a weekly basis where possible, but sometimes payment (especially for the nobility and gentry, who generally couldn't desert) could be six months or a year in coming if the Crown's finances were in particularly bad shape, as they were between 1295 and 1303. Soldiers would be paid for the period they served, including Sundays and Holy Days in contrast to civilians, and this typically between one and two months, unless the muster took particularly long or a major siege was involved.

I'd like to add a follow up question: Is there any truth to the statement that soldiers were partially paid by being allowed to loot? If so, how common/widespread was that and what period of history was it most common in?
