Quick formula

Net Profit = Revenue − variable costs − ad spend − subscriptions − fixed overhead.

Break-even Orders = fixed monthly costs ÷ contribution profit per order before those fixed costs.

How the Monthly Profit Calculator Works

The calculator converts monthly revenue and order volume into average order value, then applies your per-order costs, percentage fees, refund reserve and monthly fixed costs. This lets you see both contribution economics and bottom-line monthly profit.

Gross Profit vs Net Profit

Gross profit in this tool is revenue after modeled product, shipping, order-level fees, refund reserve and other variable costs. Net profit then subtracts advertising, subscriptions and other fixed monthly overhead.

Break-even Orders and Revenue

The calculator estimates how many orders are needed for contribution profit to cover your monthly ad spend, subscriptions and fixed overhead. It assumes the current average order value and per-order economics remain similar as volume changes.

Example: if average order value is $40 and contribution profit before monthly fixed costs is $20 per order, then $3,000 of monthly fixed costs requires about 150 orders — approximately $6,000 of revenue — to break even.

Frequently Asked Questions

Should ad spend be treated as fixed or variable?

This monthly model treats the entered monthly ad spend as a fixed amount for break-even planning. For per-order acquisition economics, use the Dropshipping Profit or Break-Even ROAS calculator.

Can I use total COGS instead of COGS per order?

This version expects COGS per order. If you only know total monthly COGS, divide it by monthly orders first.

Why can break-even orders be higher than current orders?

That means your current contribution per order is not yet enough to cover the entered monthly advertising and overhead at current volume.

Is annualized profit a forecast?

It is only the current monthly model multiplied by 12. It does not account for seasonality, scaling changes, price changes or shifts in advertising efficiency.
