Measurement of investment return that relates current income to the investment cost. Example: Brian Whyke bought a parking lot for $150,000, which generates annual revenue of $90,000, annual expenses including property taxes, insurance, and operating expense totals $60,000. Annual income before taxes then is $30,000. The current yield is 20%:$30,000/$150,000=20%. See also return; yield; yield to maturity (YTM).
