How Many Sales Do I Need?

Calculate monthly or annual sales and daily selling pace from your profit goal, price, variable costs, fees and fixed overhead.

01 / YOUR INPUTS
Delivery, product and other per-sale costs. Exclude fees entered separately below.
Applied to selling price. For a different fee basis, enter its amount as a fixed fee instead.
Additional transaction fee, not fixed overhead. Do not count it twice.
Costs for the same period as your goal.
Whole working days for the selected month, year or campaign. Adjust this when changing the planning period.

Use the same month for your goal and costs. Changing period relabels; it does not convert inputs. Use consistent tax-exclusive amounts. Currency changes formatting, not exchange rates. Inputs reset when you leave or reload this page.

Sales to reach your goal

Revenue$10,000.00
Expected profit$5,000.00
Contribution / sale$30.00
Average sales / selling day9.09
Daily pace (rounded up)10

Target means profit after variable costs, separate fees and fixed costs, before income tax. Do not also include those fees in variable cost. Include per-sale advertising in variable cost, or use the full planner. Daily pace rounds up; meeting it every selling day can exceed the period target.

How many sales do I need?

Required sales = round up ((profit goal + fixed costs) / contribution per sale). Contribution is selling price minus variable costs and fees. If contribution is zero or negative, more sales cannot reach a positive profit goal under these assumptions.

How many sales do I need to make $10,000 per month?

For $10,000 monthly operating profit, a $50 price, $20 variable cost and $1,000 monthly fixed costs require 367 sales. Contribution is $30 per sale, so (10,000 + 1,000) / 30 rounds up to 367. Over 22 selling days that averages 16.68 sales daily; a rounded daily pace is 17. Revenue is $18,350 and modeled profit is $10,010, before income tax. Fees are assumed to be included in the $20 cost.

If you mean $10,000 revenue instead, you need only 200 sales at $50. With those same costs, profit is $5,000. Follow the complete profit-goal example.

How many products must I sell to replace my salary?

A $4,000 monthly operating-profit target with $1,000 overhead and $30 contribution per sale needs 167 sales, producing $4,010 modeled profit. This does not establish the take-home equivalent of a salary: tax, benefits, reserves and withdrawal arrangements need a separate assessment. Understand profit, revenue and cash first.

How many customers do I need to break even?

With $1,000 fixed costs and $30 contribution per sale, 34 sales cover costs and leave $20. That means 34 customers only if each buys once. Repeat orders and multiple products per customer change the customer count. Calculate your break-even threshold.

How many sales do I need to make $100,000 a year?

A $100,000 annual operating-profit goal, $12,000 annual fixed costs and $30 contribution per sale require 3,734 sales. With 264 selling days, the daily average is 14.14; rounding the daily pace up gives 15. Dividing the annual goal into separate monthly targets can produce a different rounded total. Seasonality and cash timing are not modeled here.

How do I calculate profit per sale, including fees?

At a $50 price, $20 variable cost, 3% fee on price and $0.30 fixed transaction fee, contribution is $28.20: 50 − 20 − 1.50 − 0.30. A $10,000 goal plus $1,000 overhead then needs 391 sales, leaving $10,026.20 operating profit. Do not also include the same fees in variable cost. Explore contribution and total operating profit.

What if I pay to acquire sales?

The reverse planner subtracts paid traffic share × cost per click / conversion rate from each sale’s contribution. It assumes the same conversion rate for paid and organic visitors. Demand, capacity and organic content costs are not inferred. Use the reverse planner for advertising and the pricing guide to compare explicit price and volume assumptions.

All examples are hypothetical, use one currency and exclude income tax. The default period is monthly; changing the period does not convert profit or fixed-cost inputs. Selling days default to 22 for a month or campaign and 264 for a year; adjust them to your own schedule. Interactive changes require JavaScript; the formulas and examples above remain readable without it.

UNDERSTAND YOUR NUMBERS

The formula, without the mystery.

Contribution per sale = price − variable cost − price × fee rate − fixed fee per sale. Sales = ceil((target profit + fixed costs) / contribution per sale). Daily average = sales / selling days.

A worked example

To earn 5,000 after 1,000 of fixed costs, at a 50 selling price and 20 variable cost, you need 200 sales. Revenue is 10,000; profit is 5,000.

Is my sales target the same as revenue?

No. Revenue is sales multiplied by price. Profit subtracts variable and fixed costs. Plan from profit when your goal is money left in the business.

Keep the assumptions consistent

Use one planning period and one currency. Enter amounts consistently excluding sales tax or VAT. These simplified models do not account for uncertainty, inventory limits, working capital or progressive taxes. Results are planning estimates.
