Expense formulas vary, but the simplest is Total Expenses = Total Revenue - Net Income, while Operating Expenses (OpEx) involve summing costs like rent, salaries, marketing, and utilities; a key formula for this is Operating Expenses = SG&A + R&D + Other Operating Costs, or adding specific items like supplies, insurance, payroll, etc., to find your total. For personal use, it's just adding up everything spent in a period (groceries, rent, etc.) to see where your money goes.
How do you calculate total expenses? Subtract your net income (or loss) from the total revenue. If the result is negative, treat it as a net loss.
An expense ratio is the total annual expenses of the fund divided by the fund's total net assets. For example, if a fund had total annual expenses of $1,000,000 and net assets of $100,000,000, the expense ratio would be 1%. If you invest $10,000 in this fund, you'll pay $100 in fees each year.
50% of your net income should go towards living expenses and essentials (Needs), 20% of your net income should go towards debt reduction and savings (Debt Reduction and Savings), and 30% of your net income should go towards discretionary spending (Wants).
What is the total cost formula? First, you have to identify the total number of units produced (i.e. the number of product units manufactured throughout a specific time period). The formula for the total cost is as follows: Total Cost of Production = (Total Fixed Cost + Total Variable Cost) x Number of Units.
Cost Accounting Formulas
To calculate the percentage of a total, divide the part (the specific amount) by the whole (the total amount) and then multiply the result by 100 to get the percentage. The simple formula is: (Part / Whole) × 100 = Percentage (%). For example, if 10 dogs are in a group of 40 animals (10 / 40 = 0.25), then 0.25 * 100 equals 25%, so 25% of the animals are dogs.
The 50-30-20 rule recommends putting 50% of your money toward needs, 30% toward wants, and 20% toward savings.

The formula for calculating the expense ratio is: Expense Ratio (%) = (Total Operating Expenses / Average Net Assets) × 100. From an investor's perspective, a good expense ratio for an actively managed portfolio is around 0.5% to 0.75%.
A good expense ratio is generally low, often under 0.2% for index ETFs/mutual funds and under 1% (ideally 0.5-0.75%) for actively managed funds, but the ideal depends on the fund type, as passive index funds have much lower costs than active funds. Aim for the lowest possible fees, especially for broad market index funds, as high fees significantly reduce long-term returns, with ratios over 1% often considered high and warranting scrutiny.
An expense ratio measures how much you'll pay over the course of a year to own a fund. The expense ratio is measured as a percent of your investment in the fund. For example, a fund may charge 0.30 percent. That means you'll pay $30 per year for every $10,000 you have invested in that fund.
