Net Profit Calculator

The net profit calculator works out your bottom line, the money left over once every expense has been taken out of your revenue. You enter your total revenue and your total expenses for the period, and the tool returns your net profit in dollars along with your net profit margin as a percentage. Total expenses should capture everything it costs to run the business, including the cost of goods sold, wages, rent, power, marketing, insurance, interest, depreciation, and any tax you want to account for. Net profit is the figure that ultimately tells you whether the business is making money, so it is the number owners, investors, and lenders look at most closely. A New Zealand small business owner, contractor, or company director can use it to check that sales are doing more than just covering costs and to compare one period against another. To get an accurate result, make sure revenue and expenses cover the same time frame and that no costs are left out, because missing expenses make profit look better than it really is. Compare your net profit and margin across several periods so you can see the trend rather than reacting to one month. If profit is thin or negative, work back through the expense list to find what is eating the margin, and check whether prices have kept up with rising costs. A healthy net profit gives you room to reinvest, pay down debt, and build a buffer. All figures are in New Zealand dollars and the result is an estimate to support decisions, not a replacement for advice from your accountant.

Net profit = revenue - total expenses. Net margin = net profit / revenue. Estimate only, not financial or tax advice.
