Net proceeds is the gross amount you receive less any costs, mortgages, or liens paid.Net profit is the gain in money or equity, which means the gain above the initial cost (after taking out costs, mortgages, etc.).Example: you bought a home for $200k. You can sell it for $300k. There is no mortgage, but lets assume that the costs of sale (including the realtor fee, etc.) is 7% of the sale price, or $21k.The net proceeds is $279k: the $300k less the 7% in costs.The net profit is $79k: you take the $21k in costs out, then the profit is the gain over the original sale price (so $279k after costs - $200k original price), the same way that if a store buys some goods for $10 and sells them for $22, the profit is $12.
