= B2 / A2 (Then format cell as with desired decimal places.) Example | Total Units (A) | Passed First Time (B) | RFT (C) | |----------------|----------------------|---------| | 500 | 470 | =470/500 → 94% | 3. Multi-Step Process RFT If a process has multiple independent steps, the overall RFT is the product of each step's RFT.
Step1 RFT = 95%, Step2 RFT = 90%, Step3 RFT = 98%
1. What is RFT? RFT stands for Right First Time . It is a key performance indicator (KPI) used in quality management, manufacturing, and service operations. RFT measures the percentage of products or processes completed correctly without any rework, repair, or defect. rft formula in excel
| A | |---| | Pass | | Pass | | Fail | | Pass |
= B2 / A2 * 100 Or formatted as percentage: = B2 / A2 (Then format cell as with desired decimal places
= AND(B2="Pass", C2="Pass", D2="Pass") Then RFT:
RFT (%) = (Number of units that pass quality inspection on first attempt / Total number of units produced) × 100 Excel does not have a built-in =RFT() function. Instead, you calculate it using basic arithmetic. Basic RFT Formula in Excel | A | B | C | |---|---|---| | Total Units | Units with no rework/defects | RFT (%) | What is RFT
to check if all criteria are "Pass":
= COUNTIF(A2:A5, "Pass") / COUNTA(A2:A5) Format as percentage. If each unit must pass several checks (e.g., Appearance, Function, Packaging):
= B2 * B3 * B4 → Result: 4. Using COUNTIF / COUNTA for RFT from Raw Data If your data has pass/fail status:
= 0.95 * 0.90 * 0.98 Or using cell references:
