Enter your monthly units to estimate the Delhi domestic electricity bill — energy charge plus fixed charge, before duty and PPAC.
What Is an India Electricity Bill Calculator?
An India electricity bill calculator estimates the Delhi domestic bill: 600 units → energy ₹3,200.00 + fixed ₹125.00 = ₹3,325.00, before 5% duty, PPAC surcharge and subsidy. Delhi’s slabs (FY2026-27): 0–200 at ₹3, 201–400 at ₹6.25, 401–800 at ₹6.75, 801+ at ₹8. The Delhi government gives a zero bill up to 200 units — the biggest “slab” of all.
How to Use
- Enter monthly units.
- Click “Estimate Bill”.
Formula
200×3 + 200×6.25 + 400×6.75 + rest×8; + ₹125 fixed; duty and PPAC extra.
Worked Example
600 units: 200×3 = 600; 200×6.25 = 1,250; 200×6.75 = 1,350; energy = ₹3,200.00; + ₹125 fixed = ₹3,325.00 (before duty/PPAC).
How It Works, In Plain Words
Delhi’s domestic tariff is a staircase, not a single rate, and the tool climbs it the same way your discom does. Your month’s units fill the slabs in order: the first 200 units are charged at ₹3 each, the units from 201 to 400 at ₹6.25, those from 401 to 800 at ₹6.75, and anything beyond 800 at ₹8. Crucially, only the units inside a slab pay that slab’s rate — crossing into a higher slab never re-prices the cheaper units below it. The worked example shows the climb for 600 units: 200×3 = 600, then 200×6.25 = 1,250, then 200×6.75 = 1,350, giving an energy charge of ₹3,200.00.
On top of the energy charge the tool adds the ₹125 fixed charge and reports the two separately, plus the estimated total of ₹3,325.00 for the example. Just as important is what the result leaves out, stated under the estimate itself: the 5% electricity duty, the PPAC surcharge and the Delhi government subsidy are not in that total. Treat the figure as the solid core of the bill — the part fixed by the FY2026-27 tariff this page uses — with those three adjustments still to come.
Real-World Uses
A Delhi household budgeting for a heavy summer month reads the meter, enters the units, and sees the energy and fixed charges before the bill arrives — no surprise when it lands. A tenant on a shared meter uses the estimate to agree a fair split with the landlord, working from the same slab maths the discom applies rather than a guessed flat rate. And a careful small household checks how far its usage sits from the 200-unit line, since the page explains that eligible domestic consumers get a zero bill up to 200 units — a threshold worth knowing about before the month ends, not after.

Common Mistakes
- Forgetting PPAC (~16–17% extra) and 5% duty
- Assuming all-India rates — every discom differs
- Missing the 200-unit subsidy if eligible
Common Mistakes to Avoid
The commonest shock is comparing this estimate with the final bill and assuming the tool erred: as the list above warns, PPAC adds roughly 16–17% and the duty 5%, and neither is inside the estimate. The second mistake is geography — these are Delhi slabs for BSES/TPDDL areas, and assuming all-India rates fails immediately because every discom sets its own. Third, eligible households sometimes miss the 200-unit subsidy entirely by never checking their position against it. Finally, do not price a whole month at the highest slab your usage touches: units are charged slab by slab, which is why 600 units produce ₹3,200 of energy charges here rather than a single-rate figure.
FAQ
What are Delhi’s current slabs?
0–200: ₹3; 201–400: ₹6.25; 401–800: ₹6.75; 801+: ₹8 (FY2026-27).
Worked example for 600 units?
Energy ₹3,200 + fixed ₹125 = ₹3,325 before duty/PPAC.
Is electricity free up to 200 units in Delhi?
Yes — the Delhi government scheme gives a zero bill up to 200 units for eligible domestic consumers.
What is PPAC?
Power Purchase Adjustment Cost — a variable surcharge (~16–17%) on top of energy charges.
Does this work for other states?
No — slabs differ by discom; this is Delhi (BSES/TPDDL) only. Slabs last verified: October 2026.
Why is my actual bill higher than this estimate?
Because the estimate stops at the energy charge plus the ₹125 fixed charge. The real bill then adds the 5% electricity duty and the PPAC surcharge — about 16 to 17 percent on energy charges, as this page notes — which is why the tool calls its figure an estimate and lists what is still to come.
Do the slabs apply per month?
Yes — the figure you enter is one month’s units in kWh, and the slabs are applied to that month’s consumption: the first 200 units at ₹3, the next band at ₹6.25, and so on up the staircase, exactly as the worked example splits 600 units across three slabs.
