Frequently asked questions

What does Short Selling Profit Calculator do?

Work out the gross and net result of a short sale: borrow fee, margin interest, commissions, return on the margin deposited and the break-even cover price — with the unlimited-loss and margin-call risks spelled out.

What does it take into account?

It factors in borrow fee, margin interest, commissions, return on the margin deposited and the break-even cover price — with the unlimited-loss and margin-call risks spelled out. Change any of them and the output follows immediately.

When would I actually use this?

Comparing two investments that pay at different times, deciding whether a project clears its cost of capital, and sanity-checking a valuation someone else produced.

What is the most common mistake?

Trusting a valuation without asking what share of it comes from the terminal value. Past 70%, the answer is an assumption about the distant future dressed up as a calculation.

How is Short Selling Profit Calculator different from Stop-Loss & Take-Profit Calculator?

They sit next to each other but answer different questions: Stop-Loss & Take-Profit Calculator is the one to open when you need it to place the stop and target of a long or short position from a risk:reward ratio, two percentages or two exact prices — with risk and reward per share, the realised R:R, the break-even win rate and optional position sizing. Pick whichever matches what you're starting from — both are free.

Is there a tool for the next step?

Crypto profit calculator is the closest one after this: Compute the profit and ROI of a crypto trade from buy and sell prices.

What else is worth having open alongside it?

Capital Gains Yield Calculator and Dividend Payout Ratio Calculator — they come up in the same task often enough to be worth a second tab.

Where do the figures come from?

Discounting, IRR and payback are defined identically everywhere, so the arithmetic is not in dispute — the assumptions you feed it are. Change the discount rate by a point and re-read the answer.

ExplainerPrice Return, Total Return and Yield Are Three Different NumbersThe index quoted in the news is almost always a price index. At 5 percent price growth and a 2.5 percent reinvested yield, 30 years turn $10,000 into $43,219 on price and $90,656 on total return — the price measure misses 58.8 percent of the gain.ExplainerDividend Reinvestment: What Actually Drives the DifferenceReinvesting a 3 percent yield for 30 years turns 100 shares into 242.7 and multiplies the final position by exactly that factor: $32,434 becomes $78,726. Tax at 30 percent on each dividend costs $18,223 of it — nearly two and a half times the tax actually paid.ExplainerTax-Equivalent Yield: Comparing a Tax-Free Bond With a Taxable OneTaxable-equivalent yield = tax-free yield ÷ (1 − marginal rate). A 3.00 percent tax-free yield is worth 3.85 percent at a 22 percent marginal rate and 5.07 percent at 40.8 percent. The trap is that it is the marginal rate, surtaxes and social levies included — leaving them out costs 0.85 points of yield.GuideWhere to Set a Stop-Loss and a Take-ProfitThe stop goes where your idea is wrong, not where your comfort runs out — and then the position size adapts to it. Here is the volatility argument, the sizing arithmetic, and the win rate each reward multiple demands.ExplainerRisk/Reward Ratio Explained: The Win Rate Each Ratio RequiresA 1:3 ratio does not make you right more often — it lets you be wrong three times out of four and still break even. Here is the inversion, a table of ratio against required win rate, and what costs do to both.GuidePosition Sizing: What the 1 Percent Rule Actually ConstrainsThe rule caps the loss, not the position. Here is the formula, a worked example, and what a run of ten losses costs at 1 percent versus 2 percent.
