Small tools for clearer pricing.

Margin Grove helps you work out what to charge and understand what you keep from a sale. The calculators are free to use, with no sign-up.

Choose a starting point

• Margin & markup starts with your cost and selling price. It shows gross profit, margin as a share of price, and markup as a share of cost.
• Target selling price starts with your cost and the gross margin you want. It finds a price that reaches that target.
• Discount impact shows how a discount changes your gross profit and how many sales you would need to make the same total gross profit.

What to enter as cost

Use what the item costs you, ready to sell. That might be a purchase cost, or the materials and direct labor needed to make it. Use the same basis for your cost and selling price: one item, one service, or one job.

Margin and markup use different starting points

If something costs $55 and sells for $100, the gross profit is $45. The margin is 45% of the selling price. The markup is about 81.8% of the cost. Both describe the same sale.

What these results include

Gross profit is selling price minus the cost you enter. These tools do not separately deduct overhead, advertising, payment fees, or income tax. They do not calculate net profit or add sales tax. If you need those expenses included, account for them separately when deciding your final price.

Rounding and discounts

Money is calculated in cents and displayed with two decimal places. Target selling prices round up when needed to meet your margin. Discounted prices round to the nearest cent, and required sales round up to whole units.

The discount calculator assumes your cost per item stays the same as sales increase. A larger sales target is a mathematical comparison, not a forecast of customer demand. Selling below cost produces a gross loss.
