Dynasty Trade Calculator
Use this free dynasty trade calculator to work out the profit, loss and return on any trade — enter your buy price, sell price and quantity.
This calculator works out the profit or loss on any trade — you enter the numbers yourself. It is not connected to any game or trading platform.
Fees are any commission or cost of the trade. Leave the box at $0 if there are none.
Enter your buy price, sell price and quantity to see the result.
This only does the maths on your numbers — it is not financial advice.
How to use this dynasty trade calculator
Step 1: Type in the buy price per unit — the price you paid for one unit of whatever you traded. Then type in the sell price per unit — the price you sold it for, or the price you expect to sell it for. Both prices should be for the same unit, so the maths lines up.
Step 2: Enter the quantity, meaning how many units you bought and sold. If you bought 100 units and sold 100 units, type 100. If you pay any fees on the trade, such as a commission or a platform charge, put that total in the fees box. If there are no fees, leave it at $0.
Step 3: Read the result, which updates live as you type. You will see the total cost, the total revenue, the profit or loss in dollars, the profit as a percentage, and the break-even sell price. Change any number and the result changes straight away, so you can test different sell prices before you decide.
Worked example: buy at $50, sell at $65
Imagine you buy 100 units at $50 each and sell them at $65 each, with no fees. First, work out the total cost: $50 multiplied by 100 is $5,000. That is the amount you paid in total. Next, work out the total revenue: $65 multiplied by 100 is $6,500. That is the amount you receive in total.
Now take the revenue and subtract the cost: $6,500 minus $5,000 is $1,500. That is your profit. To find the profit as a percentage, divide the profit by the total cost and multiply by 100. So $1,500 divided by $5,000 is 0.30, which is 30.0%. The break-even sell price is the total cost divided by the quantity, which is $5,000 divided by 100, or $50.00. Sell above $50 and you make a profit; sell below it and you make a loss.
Try the same trade with fees. If the fees were $40, the profit would be $6,500 minus $5,000 minus $40, which is $1,460. The break-even price would rise to $50.40, because the fees have to be covered too. That is why the fees box matters: even a small fee changes the price at which the trade starts to pay.
What the break-even price means
The break-even sell price is the sell price at which the trade makes exactly nothing — no profit and no loss. It is the total cost plus any fees, divided by the quantity. In the example above, with no fees, the break-even price is $50.00, the same as the buy price. Add $40 of fees on 100 units and the break-even price becomes $50.40, because each unit has to cover 40 cents of fees as well as its $50 buy price.
Anything above the break-even price is profit, and anything below it is a loss. That makes it a useful number to know before you sell. If the price you are being offered is below the break-even price, you know at a glance that the trade will lose money. If it is above the break-even price, you know the trade will make money, and you can use the profit figure to see exactly how much. The break-even price also helps when you are comparing trades: a trade with high fees needs a higher sell price just to break even, even if the buy and sell prices look attractive at first.
Profit in dollars versus profit as a percentage
A profit of $1,500 sounds like a lot, but its meaning depends on how much money was at stake. In the worked example, $1,500 of profit on a $5,000 trade is 30.0%. That is a strong return. But the same $1,500 of profit on a $50,000 trade is only 3%. The dollar amount is the same, yet the return is ten times smaller. The percentage is what lets you compare trades fairly, because it puts every trade on the same scale.
Think of it the other way round, too. A 30% return on a small trade may be worth less in dollars than a 5% return on a very large trade. The dollar profit tells you how much money you actually made, and the percentage tells you how hard your money worked. Both numbers matter, which is why this dynasty trade calculator shows both. Use the dollars to see the cash result, and use the percentage to judge whether the trade was a good use of the money compared with other trades you could have made.
Frequently asked questions
What does this calculator work out?
It works out the profit or loss on a trade from the numbers you enter: the buy price, the sell price, the quantity and any fees. It shows the total cost, the total revenue, the profit or loss in dollars, the profit as a percentage, and the break-even sell price.
What should I put in the fees box?
Put in any commission or cost of the trade, such as a broker fee, a platform charge or a transfer fee. Add the fees together and enter the total. If there are no fees, leave the box at $0.
What is the break-even sell price?
It is the sell price at which the trade makes exactly nothing. It is the total cost plus fees, divided by the quantity. Sell above it and you make a profit; sell below it and you make a loss.
Can a trade show a loss?
Yes. If the total revenue is less than the total cost plus fees, the calculator shows the result as a loss in red, as a negative number. For example, buying 50 units at $120 and selling them at $110, with $25 of fees, gives a loss of $525.
Is this financial advice?
No. This calculator only does the maths on the numbers you enter. It is not financial advice and it does not tell you what to buy or sell. Always make your own decisions, and seek professional advice if you need it.
