About BD Bill Calculator
A free, accurate, open-source electricity bill calculator for Bangladesh.
BD Bill Calculator helps households, businesses, and industries in Bangladesh estimate their monthly electricity bills with confidence. It supports every distributor — DESCO, DPDC, BPDB, NESCO, WZPDCL, and BREB (PBS) — and every consumer category, from residential lighting to extra-high-tension industrial loads, using the latest BERC-approved tariff rates.
What you can do here
All distributors
DESCO, DPDC, BPDB, NESCO, WZPDCL, and BREB (PBS) — one calculator, same accuracy across all of them.
Every consumer category
Residential, agricultural, industrial, commercial, educational, and street lighting — across LT, MT, HT, and EHT voltage levels.
Smart meter & Time-of-Use
Enter peak, off-peak, and super-off-peak units separately so your estimate matches your smart meter bill.
বাংলা & English
Fully bilingual interface and documentation, so you can read your bill in the language you prefer.
Why this exists
Electricity bills in Bangladesh combine tiered tariffs, demand charges, and a 5% VAT — easy to misread on a paper bill. This site exists so anyone can verify their charges in seconds, plan ahead for high-usage months, and understand exactly where every taka goes.
Where the numbers come from
Tariff rates are taken from the Bangladesh Energy Regulatory Commission (BERC) gazette and cross-checked against each distributor's published charts. The full rate table — and the date it was last updated — lives on the Tariff page.

The calculation engine is published on npm as electric-bill-bd. Anyone can audit it, embed it in their own app, or contribute fixes. The site itself is built with Next.js, React, TypeScript, and Tailwind.

I'm a software engineer from Bogura, Bangladesh, with 10+ years of front-end experience. I built this calculator on the side because the paper bills in our area kept surprising my family — I wanted a quick way to double-check them. If it's helpful to you too, that's a bonus.
