Well, neither price nor value are actually "markups" over anything.

However, price can be broken down into a part corresponding to cost-price
and another corresponding to profit. Profit can be expressed as a "markup"
over cost-price, giving the profit rate (assuming fixed capital = 0).

The substance of value is indeed the labor time required to (re)produce a
commodity but, as part of this labor time is just surplus labor, we can
express that surplus labor as a "markup" (so to say) over cost-price in
labor time terms.
