01 / The essentials
The numbers first
The chart follows
An Excel waterfall chart turns a starting total and signed changes into a visual reconciliation Totals sit on the baseline; increases and decreases float between them
Keep the calculation in the worksheet and the presentation in the chart — the three habits below catch the most common errors before formatting begins
Sign
Enter reductions as negative numbers
Calculate
Make subtotal and closing rows formulas
Anchor
Mark the starting, subtotal and closing bars as totals
02 / The example
From $412m to $431m
With a useful checkpoint
Enter the labels and values below in A3:B13 — organic revenue reaches $458.8m before foreign exchange and disposals bring the close to $431m — figures are illustrative
| Row | A · Step | B · Value |
|---|---|---|
| 4 | Opening revenue | 412.0 |
| 5 | New customers | 58.4 |
| 6 | Expansion | 23.9 |
| 7 | Price | 11.2 |
| 8 | Churn | −34.6 |
| 9 | Downgrades | −12.1 |
| 10 | Organic revenue | =B4+SUM(B5:B9) |
| 11 | FX | −9.3 |
| 12 | Disposals | −18.5 |
| 13 | Closing revenue | =B10+SUM(B11:B12) |
Organic 458.8 → Closing 431.0 → Net change +19.003 / In Excel
Four steps from cells to chart
- 1
Select the source range
Highlight A3:B13 so Excel receives the step names and values — include the calculated subtotal and closing rows
- 2
Insert the waterfall
Choose Insert → Waterfall — Excel places positive and negative changes in sequence
- 3
Anchor the three total bars
Select the opening bar as an individual data point, right-click and choose Set as Total — repeat for Organic revenue and Closing revenue
- 4
Finish with readable labels
Add data labels and subtle connectors — use one colour for totals and distinct colours for increases and decreases — keep the chart title focused on the finding
