Understanding Flow-Through Percentage
How we calculate. Flow-through % = Δ profit ÷ Δ revenue × 100. See our methodology and accuracy policy .
Real-world scenario: A typical Flow-Through Percentage case uses incremental profit 8000 and incremental revenue 20000. Enter the same figures below to reproduce the worked path.
What is Flow-Through Percentage?
A hotel P&L conversion KPI. Distinct from GOPPAR (profit÷rooms available) and hospitality labor cost %.
- Same P&L basis for both deltas
- Incremental = current − baseline
- Revenue and profit definitions frozen
The Formula
Worked Example
Common Use Cases
- Budget vs actual: profit conversion
- Revenue events: how much flowed to GOP
- Owner packs: incremental efficiency
Pro Tips
- Label GOP vs NOI carefully
- Negative revenue delta needs context
- Pair with RevPAR / TRevPAR
| Scenario | When to use |
|---|---|
| Percent of a number | Finding a part of a whole (tax, tip, score) |
| Percent change | Comparing old vs new values |
Limitations: Flow-Through Percentage results are educational hotel and restaurant planning aids—not accounting, tax, or franchise reporting advice. Confirm definitions with your PMS, POS, and brand standards.
Common mistakes
- Swapping part and whole: The denominator must be the full total, not a subset.
- Rounding too early: Carry extra decimal places through multi-step work before rounding the final percent.
- Mixing percent and decimal forms: Enter rates in the format the calculator labels expect.
