Estimate the economic gain from a property sale by subtracting the purchase price and entered buying, improvement and selling costs.
Economic gain = sale price − purchase price − additional costs − selling costs.
Selling for 190,000 after paying 150,000 to buy, 10,000 in additional costs and 5,000 to sell produces an economic gain of 25,000.
Economic profit is not taxable capital gain. Local rules can treat improvements, main residences, ownership periods, indexation and exemptions differently. Mortgage repayment affects cash received but is not itself an acquisition cost in this formula.
