What is Long-Term Capital Gains (LTCG) tax?
Long-Term Capital Gains (LTCG) arise when you sell listed shares or equity mutual funds held beyond the qualifying period. Equity LTCG enjoys an annual exemption, and gains above it are taxed at a concessional flat rate. Understanding this is the first step to using the LTCG Calculator effectively, because the quality of your result depends on the assumptions you feed in. Because of the annual exemption, timing sales across financial years can reduce the tax you pay. Once you are clear on the concept, the calculator simply does the arithmetic for you — quickly, consistently and without errors.
How does the LTCG Calculator work?
The calculator applies a standard, well-established formula so the result is consistent and reliable. In simple terms, it works out the taxable long-term gain after the annual exemption, then the flat LTCG rate on the balance. The core formula is:
the calculator subtracts the exemption and applies the equity LTCG rate to the remaining gain. The tool does this instantly and re-calculates the moment you change any input, so you can test different scenarios in seconds — something that would take much longer, and be far more error-prone, on paper or in a spreadsheet.
Why use the LTCG Calculator online?
Doing this calculation manually means juggling powers, percentages and long formulas where a single slip changes the answer. The LTCG Calculator handles all of that for you and lets you compare multiple scenarios side by side, so you can see exactly how a change in one number affects the outcome. It is the fastest way to turn a rough idea about Long-Term Capital Gains (LTCG) tax into a concrete, reliable figure you can plan around — on any device, at any time, for free.

LTCG Calculator: example calculation
A ₹3,00,000 long-term equity gain, after the annual exemption, leaves a taxable amount on which LTCG is charged at the concessional rate — the calculator shows the tax due. You can reproduce this in the calculator above and then tweak the numbers to match your own situation — that is exactly what makes an online calculator so useful for planning.

Because you can see the outcome change in real time, the LTCG Calculator is as much a learning tool as a planning one: it builds an intuitive feel for how each variable — amount, rate, tenure or price — affects the final number.
Things to keep in mind
The exemption resets each financial year, so “harvesting” gains up to the exemption annually can reduce lifetime tax. Confirm the current rate and threshold. Remember that any calculator is only as good as its inputs and the assumptions built into it. Markets, interest rates, charges and tax rules change over time, so treat the output as a well-informed estimate rather than a guarantee. For decisions involving significant money or tax, confirm the current rules and consider speaking to a qualified financial adviser.
