Break-even price calculatorFees on both sides mean you don't break even at your buy price — you break even a little above it. Enter the buy price and the buy/sell fees and get the exact sell price that gets you back to zero, plus the minimum gain that price represents.Crypto DCA calculatorDollar-cost averaging: enter your fixed buy amount and the prices you bought at, and get coins accumulated, true average cost, current value and profit/loss. Break-even is your average cost — you are ahead the moment price passes it.Crypto profit calculatorCompute the profit and ROI of a crypto trade from buy and sell prices.Dividend calculatorCompute dividend income and yield from shares held.Position size calculatorCompute how many shares to buy so you risk a fixed percentage of your account.Cost of equity calculator (CAPM & DDM)The return shareholders expect, by both standard models. CAPM: Rf + β·(Rm − Rf), the risk-based approach. DDM (Gordon growth): D₁/P₀ + g, for dividend-paying stocks. Enter the inputs and it returns each estimate side by side — a key ingredient of the WACC.Mining profitability calculatorDaily coins, revenue, electricity cost and net profit from your hashrate, the network hashrate, the block reward and your power draw. It also gives the break-even coin price — the price below which you mine at a loss.Slippage calculatorThe gap between the price you expected and the price you actually got, as a percentage and as money on your trade size. Set a slippage tolerance by seeing what each percent costs before you sign the swap.

Enter Shares — buy 1, Price — buy 1, Shares — buy 2, Price — buy 2 and the Stock average calculator works out Average price, Total shares, Total cost straight away. For instance, with Shares — buy 1 = 10, Price — buy 1 = $100.00, Shares — buy 2 = 20 and Price — buy 2 = $80.00 it returns Average price = $86.67, Total shares = 30 and Total cost = $2,600.00.

How to use it

  1. Enter your values: Shares — buy 1, Price — buy 1, Shares — buy 2, Price — buy 2.
  2. Read the result instantly: Average price, Total shares, Total cost.

Frequently asked questions

What does the Stock average calculator actually compute?

It takes Shares — buy 1, Price — buy 1, Shares — buy 2 and Price — buy 2 and derives Average price, Total shares and Total cost from them. The calculation is live as you type, so the result updates on every change.

What information do I need to provide?

4 values: Shares — buy 1, Price — buy 1 ($), Shares — buy 2 and Price — buy 2 ($). Nothing else is required — no account, no file upload.

Can you show a worked example?

With Shares — buy 1 = 10, Price — buy 1 = $100.00, Shares — buy 2 = 20 and Price — buy 2 = $80.00, the calculator returns Average price = $86.67, Total shares = 30 and Total cost = $2,600.00. Those figures come from running this exact tool, so you can reproduce them by entering the same values.

What happens if I enter larger values?

It moves a lot. Using Shares — buy 1 = 20, Price — buy 1 = $200.00, Shares — buy 2 = 40 and Price — buy 2 = $160.00 instead, Average price goes from $86.67 to $173.33 — which is why it is worth testing a few scenarios rather than trusting a single figure.

What does it give for smaller values?

Scaled down to Shares — buy 1 = 5, Price — buy 1 = $50.00, Shares — buy 2 = 10 and Price — buy 2 = $40.00, Average price comes out at $43.33. The relationship is worth checking at both ends before you rely on a single result.

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 accurate is it, and what are the limits?

Estimate only — not financial advice.

What is the difference between the Stock average calculator and the Break-even price calculator?

This one returns Average price and Total shares; the Break-even price calculator returns Break-even sell price and Minimum gain needed. That is the whole difference — open the one whose figure you need.

Is there a tool for the next step?

Crypto DCA calculator is the closest one after this: Dollar-cost averaging: enter your fixed buy amount and the prices you bought at, and get coins accumulated, true average cost, current value and profit/loss. Break-even is your average cost — you are ahead the moment price passes it.
