About these tools
Which business calculator should you use?
Use the Profit Margin Calculator when revenue and costs are known. Use the Markup Calculator when you know cost and the markup you want to add to determine a selling price. Use the ROI Calculator when you know an initial investment and its total return.
Understanding margin and markup
Markup measures profit relative to cost, while margin measures profit relative to selling price. A 25% markup on a $100 cost adds $25, producing a $125 selling price and a 20% profit margin.
Measuring return on investment
ROI compares profit or loss with the initial investment. Positive ROI indicates a gain, while negative ROI indicates a loss. The ROI Calculator reports simple ROI for the period entered and does not annualize the result.
Understanding calculation limitations
Results depend on the figures entered and do not guarantee future performance. Taxes, fees, overhead, and other expenses are included only when they are already reflected in your inputs.
Frequently asked questions
What business calculators are available?
Utilities Haven currently provides calculators for profit margin, markup, and return on investment. Each calculator answers a different question about pricing, profitability, or investment performance.
What is the difference between profit margin and markup?
Profit margin measures profit as a percentage of selling price, while markup measures profit as a percentage of cost. For example, a 25% markup on a $100 cost adds $25 and gives a $125 selling price. The $25 profit is 20% of the selling price, so the profit margin is 20%.
Which calculator helps determine a selling price?
Use the Markup Calculator when you know an item's cost and the markup percentage you want to apply. It calculates the resulting selling price, gross profit, and margin.
How can I calculate return on investment?
Subtract the initial investment from the total return, divide the difference by the initial investment, and multiply by 100. The ROI Calculator performs this simple, non-annualized calculation.
Can these calculators help a small business?
They can provide consistent estimates for reviewing prices, costs, gross profitability, and investment results. The outputs support planning but do not guarantee a particular business outcome.
Do these calculations include taxes and operating expenses?
Only amounts included in your inputs are reflected. Taxes, processing fees, overhead, and other expenses are not automatically added or deducted, so use figures that match the scope of your decision.
