Understanding RFI Response Rate
How we calculate. Response % = on-time RFI answers ÷ RFIs issued × 100. See our methodology and accuracy policy .
Real-world scenario: A typical RFI Response Rate case uses answered in sla 42 and rfis issued 50. Enter the same figures below to reproduce the worked path.
What is RFI Response Rate?
A coordination KPI for design and CM teams. Late RFIs often drive field delays and change risk.
- Define the SLA clock
- Same issue set in both fields
- Segment by discipline
The Formula
Worked Example
Common Use Cases
- Design team SLAs: answer speed
- GC coordination: bottleneck RFIs
- Owner reports: information flow
Pro Tips
- Exclude withdrawn RFIs if policy says so
- Track average days separately
- Link late RFIs to delay logs
| 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: RFI Response Rate results are educational construction planning aids—not engineering, safety, legal, or cost-estimating advice. Confirm definitions with your project controls, safety, and contract documents. For earned-value SPI/CPI see the Professional hub.
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.

When to use this calculator
- Use this page when your wording matches rfi response rate and the form labels on screen.
- Use percent of a number for “what is X% of Y?” problems.
- Use number is what percent when you know part and whole and need the percent.

❓ Frequently Asked Questions
How do I use this rfi response rate calculator?
For rfi response rate, enter the values labeled on the form, then press Calculate. Compare the result to the worked example on this page.
What formula does this page use?
See the quick answer and formula box above for rfi response rate—the same percentage calculator expression is applied to your inputs.
What if my result looks wrong?
When checking rfi response rate, re-check part vs whole (or rate vs base), rounding, and whether percents were entered as 25 rather than 0.25 when the form expects percents.
