Sub-Meter Bill Divide Karne Ka Sahi Formula Kya Hai?
Pakistan mein aksar upper/lower portions ya rented apartments mein sab se barha jhagda month-end par bijli ke bill ki taqseem par hota hai. Agar landlord ya tenant purana tareeqa istemal karein jahan sirf basic unit rate lagaya jaye, to FPA (Fuel Price Adjustment), GST, Electricity Duty, aur Fixed Charges ka bojh kisi aik party par parh jata hai.
Total Bill Amount (with all taxes & FPA) ko Total Units par divide kar ke aik single composite unit rate nikala jata hai:Effective Rate = Total Rs / Total Units
Is formula se har portion apne units ke mutabiq taxes aur slabs ka hissa barabar ada karta hai.
Khatarnak ghalti yeh hoti hai ke sub-meter ke 150 units ko alag se protected slab par calculate kiya jaye jabke main meter 700+ units ki wajah se non-protected high slab par chal raha hota hai. Is se Rs 10,000+ ka deficit paida hota hai jo landlord ko bharna parhta hai.
Common Load (Pani Ki Motor) Ka Masla
Pakistan ke har ghar mein pani ki motor (1 HP se 2 HP) rozana 2–4 units khinchti hai jo mahana 60 se 120 units banti hai. Agar water motor kisi aik tenant ke meter par lagi ho to doosra tenant usko notice nahi karta. Is calculator mein aap Common Load enter kar ke usko barabar ya proportional divide kar sakte hain.
