Someone in a Viber group says they bought at 673 and sold at 750, so they made Rs. 77 per share. On 25 kitta that is Rs. 1,925.
Under the assumptions below, their estimated net profit is Rs. 1,654.52. The Rs. 270.48 difference is charges on both sides plus estimated capital gains tax, about 14.1% of the price move.
Screen-price arithmetic is the most common mistake in NEPSE profit talk. Here is how to do it properly, in the order the money actually moves.
Step 1: find what you really paid
Your cost is not the price you saw. It is the total your broker debited, divided by your quantity.
Buy 25 kitta at Rs. 673. Assume one buy transfer, one sell transfer, and a resident individual selling within 365 days on or after 16 September 2026. Round each charge to two decimal places:
| Item | Amount |
|---|---|
| Share amount (25 x 673) | Rs. 16,825.00 |
| Broker commission | Rs. 60.57 |
| SEBON fee | Rs. 2.52 |
| DP charge | Rs. 25.00 |
| Total paid | Rs. 16,913.09 |
Rs. 16,913.09 / 25 = Rs. 676.52 per share.
That Rs. 676.52 is your effective cash cost per share in this example. If you track Rs. 673 alone, you leave acquisition charges out of your cash-profit calculation. Keep this figure separate from MeroShare WACC and your broker’s tax-basis record: a raw quantity-weighted purchase price is not automatically the fee-inclusive WACC used for tax, and corporate actions can change it further.
Step 2: find what you really received
Sell the same 25 kitta at Rs. 750:
| Item | Amount |
|---|---|
| Share amount (25 x 750) | Rs. 18,750.00 |
| Broker commission | Rs. 67.50 |
| SEBON fee | Rs. 2.81 |
| DP charge | Rs. 25.00 |
| Net received before tax | Rs. 18,654.69 |
Note the commission went up, from Rs. 60.57 to Rs. 67.50. It is a percentage of a larger amount, so commission is higher in this example. Crossing a commission-rate boundary can change that comparison.
Step 3: subtract, then tax what is left
Profit before tax: Rs. 18,654.69 minus Rs. 16,913.09 = Rs. 1,741.60.
For the assumed resident-individual sale within 365 days, use the current effective 5% rate. Estimated tax on this example’s cash profit is Rs. 87.08. Your broker uses its recorded taxable gain to determine the actual deduction.
Net sale receipts after estimated tax: Rs. 18,567.61. Net profit: Rs. 1,654.52. On a Rs. 16,913.09 outlay that is a 9.78% return.
Capital gains tax applies to taxable gains, rather than gross sale proceeds. This example estimates taxable gain from cash profit after charges. Reconcile the result with the WACC and holding-period details used by your broker; an economic loss calculated from your records does not by itself prove what the broker will deduct.
The share calculator runs all three steps at once, including the break-even figure below, if you would rather not keep a spreadsheet.
Step 4: know your break-even before you need it
Break-even is the sell price at which you recover at least what you put in, at a sell-price precision of one paisa. Most people assume it is their buy price. It is not, because charges apply on both sides.
For the position above, break-even sits at Rs. 680.08, not Rs. 673. You need the price to rise about 1.05% just to get your money back.
This is worth internalising because of what it means for a stock that has "recovered." A share you bought at 673, which fell to 600 and has now climbed back to 673, is not back to even. Sell there and you are down Rs. 176.18 on the round trip. The chart looks like you broke even; your bank balance disagrees.
The framework
Four numbers, in this order, every time:
- Effective cost per share = total debited / quantity. Not the screen price.
- Net receivable before tax = gross sale minus commission, SEBON fee, DP charge.
- Profit before tax = net receivable minus total paid.
- Net profit = profit before tax minus CGT. The calculator estimates CGT on a positive cash gain; compare with your broker’s recorded taxable gain.
Once you have step 1 recorded for each holding, the rest takes a minute. The discipline that matters is recording it at purchase, while the bill is in front of you, rather than reconstructing it later from a price you half-remember.
For resident individuals, the effective rates depend on the sale date:
| Sale date | Held 365 days or less | Held more than 365 days |
|---|---|---|
| 17 July–15 September 2026 | 10% | 7.5% |
| From 16 September 2026 (2083-05-31 BS) | 5% | 3.75% |
The current effective rates follow a 50% exemption in the official tax exemption notice. These are resident-individual examples; do not use them for an entity or non-resident seller.
Where this breaks
Multiple buy lots. Weight purchase prices by quantity and keep acquisition charges separately. The calculator’s Average mode reports the raw weighted purchase price; its profit estimate also includes the buy charges. It currently assumes one Rs. 25 buy transfer charge per input lot, but several executions can share one transfer charge. CDSC’s clearing and settlement FAQ, pages 20–21, shows one Rs. 25 charge shared across a grouped transfer of 100, 200, and 200 shares. Check your actual grouping before expecting a calculator estimate to match a bill.
Partial sales. Sell 10 of your 25 and you need to allocate acquisition cost and charges to the shares sold. Transfer charges relate to settlement groups, which can contain several executions. Use the WACC and holding-period records accepted for your broker’s tax calculation when reconciling a partial sale.
The holding-period boundary. 365 days is the line, and it is counted on the actual dates, not on "about a year." If you are close to it, check the calendar before selling, because the current difference is 1.25 percentage points of your taxable gain. That said, do not hold a position you want out of purely to save Rs. 125 on a Rs. 10,000 gain.
Rates move. These examples were reviewed on 18 October 2026. The SEBON commission circular effective 14 May 2024 applies one rate to the whole transaction, rather than progressively to portions. CGT changed again on 16 September 2026. When reconciling an older sale, use the rules in force on its sale date.
Bonus and rights shares. These change your cost basis in ways a straight buy does not, and the tax treatment of the acquisition differs. Do not run them through this arithmetic without checking how your cost basis was adjusted.
What to check next
Compare your broker’s buy bill, sell bill, and MeroShare WACC for one holding. A difference from the order-screen price can reflect charges, multiple purchase lots, or corporate actions. Check each component instead of assuming the entire gap is fees.
Then read NEPSE broker commission and SEBON charges explained for where each of those charges comes from and why small trades pay proportionally more.
