How do I spread monthly overheads across each order?
Divide your fixed monthly costs by the number of orders, and you will see why selling more makes each order carry a smaller share.

Some costs arrive whether you sell one order or a thousand. Software subscriptions, a domain, rent for a small workspace, a phone bill, a part-time helper, accounting help. These are overheads, and they are easy to forget when you price a single product. Spreading them across orders shows their weight.
Add up the monthly overheads
Write every cost that does not change with the number of orders. Say your list gives:
- Tools and subscriptions
- Domain and similar renewals, divided by 12 to get a monthly figure
- Workspace or rent share
- Phone and internet
- Help or support you pay for regularly
Add them up. For this example the total is Rs 12,000 a month.
Divide by orders
If you ship 300 orders in a month, each order carries Rs 12,000 divided by 300, which is Rs 40.
Now suppose a slower month brings only 150 orders. The overheads have not changed, but each order carries Rs 12,000 divided by 150, which is Rs 80. The same product, sold at the same price, earns Rs 40 less for you simply because there were fewer orders to share the load.
At 600 orders, the share falls to Rs 20. This is why volume matters. Fixed costs get lighter with each sale.
What this does to your pricing
Take an order with Rs 350 of contribution, meaning price minus product cost, shipping and packing. After the overhead share of Rs 40, you keep Rs 310. In the slow month, with Rs 80, you keep Rs 270. In the busy month, at Rs 20, you keep Rs 330.
If you price using the busy month and sell at the slow month rate, you find at the end of the month that the profit is less than you expected, and it feels as if something went wrong. Nothing did. The overhead simply had fewer orders to hide behind.
Which number should you use for pricing?
Use a realistic average, not your best month. Look at your last three months and take a typical volume. If you are brand new and do not know yet, estimate cautiously and update after two months.
Some sellers also work out a break-even number of orders: monthly overheads divided by the contribution per order. With Rs 12,000 of overheads and Rs 350 contribution, break-even is about 34.3, so you need 35 orders a month just to cover overheads, before any profit. That is a useful target.
How to bring the share down
- Cut overheads that you do not use. Check each subscription and ask whether you open it weekly.
- Grow orders without growing fixed costs. Repeat customers help most. See the repeat customer is the whole business.
- Raise contribution per order with bundles or higher-value products.
- Share costs. If you rent a workspace, ask whether another seller can share it.
Do not go overboard
Allocation is a planning tool, not a precise science. Overhead per order shifts every month. Use it to see the shape of your business and to avoid underpricing. Review it quarterly.
For the cost to make each product, read batch production cost per unit. For pricing from a margin once overhead is added to cost, see price from a target margin, and for what to do when your month turns slow, what to do in your first 30 days online has ideas for building steady demand.
Know the monthly overhead number by heart. It is the rent your orders pay together.
