Model what happens to your trading capital if you made the same percentage return every trading day. Every day's brokerage and GST are recalculated on your current leveraged position — not your original deposit — so the numbers stay honest as your account grows or shrinks.
Set your capital, leverage and fee structure on the left. Results, the growth chart and the full daily ledger below update automatically as you change any input.
Hover the chart to inspect any trading day.
Every row is recalculated from that day's actual capital — brokerage and GST rise as your leveraged position grows. Click a row for the exact working. Click a column heading to sort.
Table scrolls horizontally on smaller screens — the page itself never scrolls sideways.
Each trading day runs through the same nine-step chain before the result becomes tomorrow's starting capital.
The balance you start the day with.
The multiplier applied to your capital to open a position.
Capital × leverage. This is what brokerage is charged on.
Capital × your daily % — calculated on capital, not position size.
% of position, a flat fee per trade, or whichever is lower — your choice.
Brokerage × your GST rate.
Gross profit − brokerage − GST.
The share of net profit added back to capital.
Today's capital + reinvested profit. The cycle repeats.
Worked example — ₹500 capital, 200x leverage, 5% daily, 0.01% brokerage, 18% GST, 100% reinvested
₹500 × 200 = ₹1,00,000₹500 × 5% = ₹25.00₹1,00,000 × 0.01% = ₹10.00₹10.00 × 18% = ₹1.80₹25.00 − ₹11.80 = ₹13.20₹500 + ₹13.20 = ₹513.20It's what happens when the net profit from one leveraged trading day is added back to your capital, so the next day's position size — and the fees and profit that come with it — is calculated from a slightly larger base. Over many days this creates exponential rather than straight-line growth, in either direction.
Brokerage is charged on the full leveraged position value, not on your actual capital. Position value equals your capital multiplied by your leverage, so brokerage scales up directly with the leverage you choose, even though your capital at risk hasn't changed.
GST is applied on top of the brokerage amount, not on your capital or profit. It's calculated as your GST rate multiplied by that day's brokerage, then added to brokerage to give total trading charges.
In this model, no — gross profit is calculated only on your actual capital, not the leveraged position. Leverage increases position size, and therefore brokerage, without increasing the gross profit percentage itself.
Yes. Because brokerage is charged on position value (capital × leverage), higher leverage directly increases the brokerage — and the GST on that brokerage — deducted from your gross profit each day.
Yes. Set "Include all calendar days" to Yes so every day, including weekends, counts as a trading day — matching how crypto markets trade continuously.
Yes. Switch the brokerage model from "% of position" to "Flat fee/trade" for a fixed charge per order regardless of size, or "Lower of both" to model a percentage capped at a flat amount — the way many Indian discount brokers price intraday and F&O trades (for example, the lower of 0.03% or ₹20 per executed order, or a flat ₹20 per order for options). The quick-fill presets pre-populate typical Zerodha-style figures as a starting point, but broker pricing changes over time, so confirm current rates on your own broker's website before relying on the numbers.
Yes. Choose "No" and pick the weekdays you actually trade, such as Monday–Friday for stock and index markets. Only those days are compounded.
