Link: What Did Medieval Items Really Cost? And How Much Did An Archer Make?
There’s an interesting table here of the wage rates of various jobs (and if you click through, goods and livestock). The snapshots were taken in different decades, often different centuries, so may not be directly comparable, since there was some major economic upheaval between the 14th and 16th centuries, and this doesn’t count benefits, which may include room, board, and equipment, and prices even varied pretty dramatically before then; they list war horse prices ranging from “up to 50 shillings” in the 12th century to “up to 80 pounds [1,600 shillings]” in the 13th century.
