English for Financial Charts and Trends: How to Describe Numbers Clearly

When presenting a financial chart, the goal is not to describe every data point. A clear explanation identifies the main pattern, the important change and the business meaning.

The basic language of movement

• Increase: rise, increase, grow, improve, climb
• Decrease: fall, decline, decrease, drop, weaken
• Little change: remain stable, remain broadly unchanged, level off, flatten
• Movement in both directions: fluctuate, remain volatile
• Highest point: peak at
• Lowest point: bottom out at

Use 'by' and 'to' correctly

This is one of the most common mistakes in financial English.

• “Revenue increased by 10%.” — the size of the change.
• “Revenue increased to $22 million.” — the final value.
• “Revenue increased from $20 million to $22 million.” — starting and ending values.

Describe the size and speed of a change

• “Sales increased slightly.”
• “Operating costs rose gradually over the year.”
• “Cash flow improved significantly in Q3.”
• “Margins fell sharply following the price increase.”
• “Revenue grew steadily throughout the period.”

Use strong adverbs such as dramatically and sharply only when the movement really justifies them.

Percent, percentage points and basis points

These distinctions matter in finance.

• “Revenue increased by 10%.”
• “The operating margin increased from 20% to 22%, a rise of two percentage points.”
• “The lending spread increased by 25 basis points.”

A move from 20% to 22% is not a two-percent increase. It is a two-percentage-point increase, equivalent to a 10% relative increase.

Compare two periods

• “Revenue was 6% higher than in the previous quarter.”
• “Net income was broadly flat year on year.”
• “The margin remained below the level recorded in 2024.”
• “Q3 performance was stronger than Q2 but weaker than the same period last year.”

Describe volatility without overexplaining

• “The exchange rate fluctuated within a relatively narrow range.”
• “Commodity prices remained volatile throughout the period.”
• “The figure fell initially before recovering in the second half.”
• “After peaking in March, volumes declined gradually.”

Separate observation from explanation

A chart shows what happened; it may not prove why it happened. Keep the two stages distinct.

• Observation: “Revenue fell by 8% in Q2.”
• Explanation: “The decline was mainly due to lower volumes in China.”

This distinction makes your presentation sound analytical rather than speculative.

A useful three-step structure

• Overview: “The overall trend is positive, despite some volatility in the middle of the year.”
• Evidence: “Revenue increased from $18 million in Q1 to $24 million in Q4.”
• Interpretation: “The improvement was mainly driven by higher client activity.”

Example chart commentary

“The chart shows a gradual improvement in operating profit over the year. Profit increased from $3.2 million in Q1 to $4.6 million in Q4, although there was a temporary decline in the third quarter. The Q3 weakness was mainly due to higher logistics costs. Overall, the underlying trend remains positive.”

The strongest chart commentary is selective. Give the audience the pattern first, then the figures that prove it, then the explanation that matters.
