= AND(B2="Pass", C2="Pass", D2="Pass") Then RFT:
= 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. rft formula in excel
= B2 * B3 * B4 → Result: 4. Using COUNTIF / COUNTA for RFT from Raw Data If your data has pass/fail status: = AND(B2="Pass", C2="Pass", D2="Pass") Then RFT: = B2
= 0.95 * 0.90 * 0.98 Or using cell references: Using COUNTIF / COUNTA for RFT from Raw
to check if all criteria are "Pass":
= B2 / A2 * 100 Or formatted as percentage:
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 (%) |
