Late Payment Calculator & Due Date Reminder
See exactly what a late SSGC bill costs: the 10% surcharge, what it becomes after another billing cycle, and where that leads if it is left. Then put the due date in your calendar so it does not happen again.

The surcharge rate used here is 10% of the unpaid amount, the standard domestic figure. Some bills also print an “amount payable after due date” — if that number differs from ours, that number is the one that counts.
What happens, and when
On the due date
Pay the lower figure printed on the bill. Anything after this is calculated on the higher one.
The day after
The late payment surcharge of 10% applies to the unpaid amount. Paying now means paying the "after due date" figure.
Next billing cycle
The unpaid amount becomes arrears on the new bill, and the surcharge applies again to the larger balance.
After sustained non-payment
SSGC may issue a disconnection notice and then disconnect the supply. Reconnection requires clearing the full outstanding amount plus a reconnection fee, and it is not instant.
Paying in the last 48 hours
Channels are not equally fast. A bank app or mobile wallet payment posts against your consumer number quickly. Cash at a counter goes through a collection and reconciliation cycle that can take a working day or more — which means a payment made on the due date may still be recorded as late. Inside the final two days, use a digital channel and keep the reference number until the next bill confirms it cleared. That reference is your only evidence if a surcharge is applied in error, and without it the conversation goes nowhere.
The surcharge at different bill sizes
A flat 10% sounds small until you see it against a winter bill. The third column is what the same unpaid amount becomes if it is carried into the next cycle and surcharged again.
| Bill amount | Surcharge (10%) | Payable after due date | After another cycle |
|---|---|---|---|
| Rs 1,500 | Rs 150 | Rs 1,650 | Rs 1,815 |
| Rs 3,000 | Rs 300 | Rs 3,300 | Rs 3,630 |
| Rs 5,000 | Rs 500 | Rs 5,500 | Rs 6,050 |
| Rs 8,000 | Rs 800 | Rs 8,800 | Rs 9,680 |
| Rs 12,000 | Rs 1,200 | Rs 13,200 | Rs 14,520 |
| Rs 20,000 | Rs 2,000 | Rs 22,000 | Rs 24,200 |
The compounding is the real danger
One late payment is an irritation. Two is a pattern that gets expensive fast, because the second surcharge is calculated on a balance that already includes the first. Households that end up facing disconnection rarely got there through a single bad month — they got there by carrying a balance forward three or four times while the arrears line grew.
Five habits that make a late bill impossible
Put the due date in your calendar
With a reminder two days out, not on the day itself. The button in the tool above does this in one click.
Register for eBill
The bill arrives by SMS and email, so a paper copy going missing stops being a reason to miss a payment.
Read morePay digitally, not at a counter
Bank apps, Easypaisa and JazzCash post quickly and give you a reference. Cash at a counter can take a working day.
Read moreCheck the bill online mid-month
Do not wait for the paper copy. The bill exists in SSGC’s system from the day it is generated.
Read moreKeep the payment reference
Until the next bill shows the payment cleared. Without it you cannot dispute a surcharge applied in error.
Watch your consumption
Bills that surprise you are the ones that go unpaid. Reading your own meter removes the surprise.

How much is the SSGC late payment surcharge?
The standard domestic late payment surcharge is 10% of the unpaid amount. That is why your bill prints two figures: a lower one payable within the due date, and a higher one payable after it. The difference between them is the surcharge.
Is the surcharge charged per day?
No — it is a one-off percentage applied to the unpaid balance once the due date passes, not a daily accrual. Being one day late and being twenty days late cost the same within a single cycle. What actually escalates is what happens next: the unpaid amount rolls into the following bill as arrears and the surcharge applies again to the larger balance.
I paid on the due date but was still charged. Why?
Almost always a posting delay. Cash paid at a counter goes through a collection and reconciliation cycle before it reaches your account, and the surcharge is applied against the balance recorded at cut-off. This is why a digital payment is safer in the final 48 hours. If you have a bank or wallet reference showing payment on or before the due date, take it to your zone office or raise it through the complaint process and ask for the surcharge to be reversed.
When does SSGC actually disconnect the supply?
Not after one missed bill. Disconnection follows sustained non-payment across billing cycles and is preceded by a notice. But once it happens, reconnection means clearing the full outstanding amount plus a reconnection charge, and the supply does not come back the same day. The full surcharge and disconnection guide sets out the sequence and what to do at each stage.
Can I pay part of the bill to avoid the surcharge?
No. The surcharge is applied to whatever remains unpaid at the due date, so a partial payment reduces the base but does not prevent the charge. If cash flow is the problem, it is worth speaking to your zone office before the due date rather than after it — an arrangement discussed in advance is treated very differently from silence followed by arrears.
Does the calendar reminder send me a notification?
The downloaded file adds an event on your due date with an alert set two days earlier. Whether you get a notification depends on your own calendar app’s settings — nothing is sent from this site, and we do not know your due date or store anything you type here.
