Power Factor Current Multiplier Table
Power Factor Current Multiplier Table lookup table with assumptions and boundary notes.
Scope
Power-factor arithmetic only. It does not determine utility penalties, capacitor sizing, or equipment acceptance.
Lookup table
Estimate how current rises as power factor decreases for the same real power.

| Power factor | Current multiplier vs PF 1.0 | Approx. current increase | Use |
|---|---|---|---|
| 1 | 1 | 0 percent | Same kW at lower power factor requires more current |
| 0.95 | 1.053 | 5 percent | Same kW at lower power factor requires more current |
| 0.9 | 1.111 | 11 percent | Same kW at lower power factor requires more current |
| 0.85 | 1.176 | 18 percent | Same kW at lower power factor requires more current |
| 0.8 | 1.25 | 25 percent | Same kW at lower power factor requires more current |
| 0.75 | 1.333 | 33 percent | Same kW at lower power factor requires more current |
| 0.7 | 1.429 | 43 percent | Same kW at lower power factor requires more current |
| 0.6 | 1.667 | 67 percent | Same kW at lower power factor requires more current |
Notes
- Check table values for preliminary lookup and arithmetic checks only.
- Confirm equipment ratings, product markings, installation conditions, utility requirements, and the local authority requirements before design or field use.
