Sub-Meter Ka Bill Calculate Kaise Karein? (Fair Formula)

Rental properties (jaise upper portion, ground portion, ya apartments) mein aksar 1 Main Meter hota hai aur mukhtalif tenants ke liye **Sub-Meters** lagaye jate hain. Month-end par jab K-Electric ya WAPDA ka main bill aata hai to sab se barha masla yeh hota hai ke:

*"Har tenant ka hissa kitna banta hai?"*

Aksar landlords ya tenants simple flat rate laga dete hain jo kisi aik party ke sath na-insaafi ka sabab banta hai. Yahan standard aur fair formula diya gaya hai.

1. The Proportional Average Unit Rate Formula

Sub-meter billing ka sab se munafas (fair) tareeqa **Total Bill / Total Units** ka average rate nikalna hai:

$$\text{Effective Unit Rate} = \frac{\text{Total Main Bill Amount (Taxes Included)}}{\text{Total Units Consumed on Main Bill}}$$

#### Example Calculation:

**Main K-Electric Bill:** Rs 24,000

**Total Main Meter Units:** 600 Units

**Effective Rate Per Unit:** $\frac{24000}{600} = \text{Rs 40.00 per unit}$

Agar **Tenant A (Ground Floor)** ke sub-meter par 220 units aaye hain:

$$\text{Tenant A Bill} = 220 \times 40 = \text{Rs 8,800}$$

Agar **Tenant B (First Floor)** ke sub-meter par 380 units aaye hain:

$$\text{Tenant B Bill} = 380 \times 40 = \text{Rs 15,200}$$

$$\text{Total} = 8,800 + 15,200 = \text{Rs 24,000 (Exact Match!)}$$

2. Common Sub-Meter Billing Mistakes to Avoid

❌ **Main Bill Aane Se Pehle Readings Lena:** Main meter ki reading date aur sub-meters ki reading date hamesha **aik hi din** honi chahiye.

❌ **Taxes aur Fixed Charges Ko Ignore Karna:** Sub-meter par sirf base rate lagane se landlord ko apni jeb se FPA aur GST bharna parhta hai. Average Unit Rate formula tamam taxes ko automatically proportionate divide karta hai.

❌ **Kharab Sub-Meter:** Agar sub-meters mechanical (purane) hon to woh ghalat readings de sakte hain. Hamesha digital sub-meters lagayein.

Frequently Asked Questions (FAQs)

Sub-meter ke bill mein Fuel Price Adjustment (FPA) kaise divide karein?

FPA ko alag se calculate karne ke bajaye poore bill ki total raqam ko total units par divide karein. Is se FPA har tenant ke units ke hisab se barabar taqseem ho jata hai.

Agar sub-meters ke total units main meter se kam hon to kia karein?

Yeh difference line losses ya shared lights (staircase/water motor) ki wajah se hota hai. Shared load ko tamam tenants mein barabar divide kiya jana chahiye.
