Power Factor Correction Calculator
Power Factor Correction Calculator — quick estimate
A low power factor inflates your billing demand (kVA) and can trigger a DISCOM penalty. Enter your load and target PF to size the capacitor bank (kVAr) and see the demand-charge you can save every year — then get an engineered APFC panel from our team.
Your load & tariff
Sizes kVAr = kW × (tan φ₁ − tan φ₂) to move from your existing PF to the target, then rounds up to a standard APFC step. Saving = the reduction in billing demand (kVA) × your demand charge.

Our electrical engineers will confirm the kVAr, staging, detuned reactors and panel scope from your load profile and bill. We'll attach the estimate above automatically.

Thanks! Our electrical team will send your tailored capacitor-bank & APFC design within one business day.
Indicative estimate only — not a binding design. Actual capacitor-bank kVAr, stages and detuned-reactor requirement depend on your load profile, harmonics (THD) and the DISCOM tariff. We confirm with a power-quality study.
Need an exact BOQ, rate analysis or measurement sheet?
This is a quick engineering estimate. For tendering, billing or audit, our QS & estimation team prepares an item-wise BOQ, rate analysis and a verified measurement sheet to IS / CPWD norms — backed by 15+ years and ISO 9001:2015 quality processes.
