Business Vocabulary for Professionals: Terms Worth Knowing
You don’t need hundreds of business terms. Start with the concepts that repeatedly appear in conversations about money, performance, decisions, and people.
This is not a dictionary. It is a curated set of terms that help you describe a situation more precisely in a meeting.
Terms worth knowing
Money
Revenue
Money the business brings in from customers before costs.
At work: “Revenue is up, but margins are still thin.”
Profit
What remains after costs are subtracted from revenue.
At work: “We can grow revenue and still lose profit if costs rise faster.”
Gross margin
The share of revenue left after direct costs of delivering the product or service.
At work: “Gross margin dropped when shipping costs spiked.”
Runway
How long the business can operate before it runs out of cash at the current burn rate.
At work: “With current spend, we have about nine months of runway.”
Performance
KPI
A key performance indicator—a metric chosen to show whether an important goal is being met.
At work: “Our KPI for onboarding is activation within seven days.”
Leading indicator
A metric that moves early and helps predict a later result.
At work: “Weekly active trials are a leading indicator for next-quarter revenue.”
ROI
Return on investment—the benefit gained relative to what was spent.
At work: “What’s the ROI of another month of paid acquisition?”
Decisions
Trade-off
A choice where gaining one thing requires giving up something else of value.
At work: “The trade-off is speed now versus rework later.”
Opportunity cost
The value of the best alternative you give up by choosing something else.
At work: “The opportunity cost of building this now is delaying the enterprise release.”
Bottleneck
The constraint that limits how fast the whole system can move.
At work: “Every release waits three days for the same security review.”
Unit economics
Whether one customer or one unit of business is profitable after direct costs.
At work: “Before we scale spend, we need cleaner unit economics.”
People
Headcount
The number of people on the team or in the company.
At work: “We can’t add headcount until the next planning cycle.”
Attrition
The rate at which people leave the organization over a period.
At work: “Attrition in support is raising training costs.”
Turn recognition into recall
A short practice session is more useful than rereading the list.
Learn → rebuild → recall → use
Try matching the concept
Try it
“We can build feature A, but doing so means feature B moves to next quarter.” What concept describes this?
Answer
“Opportunity cost.”
Two more quick checks: “Every release waits three days for the same security review” points to a bottleneck. “We have cash for six months at this spend” is runway.
