Accounting profits tend to be higher than economic profits as they omit certain implicit costs, such as opportunity costs.
For example, if you invest $100,000 to start a business and earned $120,000 in profit, your accounting profit would be $20,000. Economic profit would add implicit costs, such as the opportunity cost of $50,000 should you have been employed instead during that period. As such, you would have an economic loss of $30,000 ($120,000 - $100,000 - $50,000).
