Four vacant units out of forty total units equals 10% vacancy.

A vacancy rate of 10% is the share of units sitting empty or uncollected. Compare it against your submarket's norm: above it means lost income to chase down (pricing, condition, management); near zero can actually mean rents are set below market.
