What the E-commerce store calculator calculates

The calculator connects unit economics, monthly financial needs, customer demand and operating capacity. It first finds contribution per order, then calculates the exact orders and revenue required to cover overhead, owner pay and optional target profit. It also shows the rounded-up operating target, required inquiries and whether the team has enough productive capacity.

Inputs to gather before you start

Use recent, representative figures instead of best-case estimates. Enter average order value, product cost, fulfillment labor, shipping subsidy, returns allowance, customer acquisition cost, overhead and fulfillment capacity. Keep fixed monthly overhead separate from costs that rise with each order. If a cost applies to every sale, include it in the per-order fields.

• Weighted average order value
• COGS and fulfillment labor per order
• Shipping subsidy and expected returns allowance
• Customer acquisition cost and payment/platform fees
• Subscriptions, payroll, warehouse and other monthly overhead
• Fulfillment team hours, handling time, utilization and store conversion rate

The break-even formula

Contribution per order = average price − payment fees − direct materials − direct labor − other variable costs − acquisition cost. Required orders = (monthly overhead + owner pay + target profit) ÷ contribution per order. Exact break-even revenue = required orders × average price. MyBreakeven keeps the exact fractional result and displays the next whole order separately.

How to use the calculator step by step

• Select E-commerce store from the industry list.
• Choose the currency used by your records; the tool labels values but does not convert exchange rates.
• Enter price and every direct cost per order.
• Add monthly overhead, owner pay and optional target profit.
• Enter team hours, delivery time, productive utilization and inquiry conversion rate.
• Review exact and whole-unit targets, contribution margin, required inquiries and the capacity gap.
• Compare conservative and optimized scenarios before making a pricing or spending decision.

Worked e-commerce store example

Using the example assumptions—$86 per order, $60.75 total variable cost and $14,800 monthly financial need—contribution is $25.25 per order. The exact target is 586.19 orders and $50,411.91 revenue. Because a fraction of a order normally cannot be sold, the practical target is 587 orders, or $50,482. Estimated capacity is 1,267.50 orders; required inquiries are 20,935.18 at the example conversion rate. This example explains the calculation only and is not an industry benchmark.

How to interpret feasibility

A break-even target can be mathematically correct but operationally impossible. Compare required orders with realistic productive capacity after setup, travel, administration, gaps and rework. A negative capacity gap means the current team cannot deliver the target under the assumptions entered. Test price, service mix, variable costs, utilization or staffing one change at a time.

Common mistakes to avoid

• Using gross margin before payment fees, returns and shipping subsidy
• Mixing site visitors with qualified inquiries without defining the conversion denominator
• Using blended ad spend without matching it to acquired orders
• Ignoring fulfillment constraints during promotion periods

Ways to improve the result

Focus on the assumptions with the largest verified effect rather than changing every input at once. Test product mix, bundles, shipping thresholds, return reduction, payment costs, conversion rate and customer acquisition by channel. Recalculate after each change and preserve a conservative scenario so the plan does not depend on perfect conditions.

Frequently asked questions

What does the E-commerce store break-even calculator include?

It includes price, direct costs, payment fees, acquisition cost, monthly overhead, owner pay, target profit, required orders, inquiries and productive capacity.

Why are exact and whole orders different?

The exact result preserves the mathematical fraction. The whole-unit target rounds up because selling only part of an order is usually not operationally possible.

Does the calculator predict guaranteed profit?

No. It produces an assumption-based planning estimate. Actual sales, costs, cancellations, taxes and timing can differ.

How often should the calculation be updated?

Update it whenever price, wages, supplier costs, advertising performance, overhead or team capacity changes materially, and review it at least monthly during active planning.
