Profit calculatorThe profit calculator calculates how much the total principal has increased and how much the net profit is when you enter the investment amount and the purchase price and then enter the purchase price.The important thing here is that the fee amount is calculated so you can check the amount more accurately.2. Watering calculatorWith the floating calculator, if the price of the item you invested in falls, you can invest additional amount and check what the average unit price is.3. Target unit price calculatorThe target unit price calculator is a calculator that helps you calculate how much you can sell the items you bought to achieve the desired target amount.For example, if you invest 1 million won and purchase it at a unit price of 12 won, you will be told how much you can sell it for if you want to make the principal amount excluding commissions to 2.3 million won.
