Free Stock Profit Calculator

Calculate profit, return and break-even on a stock trade after fees and tax.

Total cost is shares times buy price plus buying fees, and proceeds are shares times sell price minus selling fees. The profit gives return and annualised return over months held; tax is applied to gains at your rate, and the break-even sell price covers the costs.

How to use the Stock Profit Calculator

  1. Enter your starting amount, regular contribution, expected return and time period.
  2. Read the end value and the split between money you put in and growth.
  3. Try a lower return as well as a higher one, because real markets are uneven.

About the Stock Profit Calculator

Calculate profit, return and break-even on a stock trade after fees and tax.

Time and consistency do most of the work in saving and investing. Running the numbers shows how small changes in rate, term or contribution add up.

Getting started with the Stock Profit Calculator

Using the stock profit calculator takes a minute or two. Your entries are saved in this browser, so you can come back later and carry on.

Tips for better results

Include every fee for a realistic return, as small trades can lose much to commissions. Tax rules vary widely, so set the rate to match your situation or to zero.

Treat the result as an illustration, not a promise. Returns vary year to year.

Fees and inflation reduce real growth, so consider both when planning.

Privacy and where your data goes

Frequently asked questions

What is the break-even price?

It is the sell price at which profit is zero after fees, which is slightly above your buy price. It is shown so you can see the effect of commissions.

Does annualised return handle short holds?

It scales the return to a yearly rate, which can look extreme for very short periods. Treat it as a comparison figure, not a forecast.

Is the stock profit calculator free?

Yes. It is free to use with no signup, no watermark and no usage limits.

Is my data private?

Yes. Your inputs are processed in your browser and saved only in its local storage. They are not uploaded to our servers.

Does it work on mobile?

Yes. Zapxa works on phones, tablets and desktops. Use the print button or download a PDF to keep a copy.
