I would like to respond to a job listing that reads, "Salary $140-$200 OTE with significant upside." What does the "OTE" mean?

OTE stands for "On-Target Earnings" and usually refers to a compensation package that has base salary plus commission and/or bonus components. The OTE amount refers to the wage amount you will receive if you hit 100 percent of your stated performance or sales goals.

The variable portion of the wage is usually paid out on a quarterly basis, but may be monthly or bimonthly, or whatever the employer chooses. It may be a preset amount that is paid as each portion of the goal is met, or it may be a percentage of the revenue flow that you have helped generate.

It's most typically seen in a sales or pre-sales position and is meant to reward you for performance which meets and exceeds goal.
