Costs

Flat per order or a percentage: your note already knows

How you are billed changes which habits are expensive. Read the plan, not a two-year-old tweet.

Two traders with identical fills can pay very different brokerage, because one is on a flat per-order plan and the other is on a percentage of turnover.

And the difference is not academic — it decides whether splitting an order into five clicks costs you nothing or costs you five times.

Flat fees punish click-splitting

On a flat per-order plan, one order for five lots costs one fee. Five separate orders cost five. On a percentage plan, the number of clicks barely matters and the size does.

Neither is better in the abstract. What matters is whether your habits match your plan.

Brokerage for the same 5 lots, different execution habits
₹0₹56₹112₹168₹224 ₹401 order₹802 orders₹1203 orders₹2005 orders

Flat ₹20 per executed order, entry and exit. On a percentage plan this chart would be almost flat.

Include GST when you quote a number

Brokerage quoted without GST understates the bill. Since GST applies to brokerage and to exchange transaction charges, the effective per-order cost is always a little higher than the headline.

Comparing brokers needs matched periods

Same product, same date range, same activity level. Anything else is marketing arithmetic. A journal that imports from more than one broker should compare only on those terms — and should never present a broker as an investment recommendation.
