In Excel or Google Sheets, shipping cost per order for a whole period is SUM(F2:F7) / SUM(N2:N7), where each SUM covers one column of monthly figures. On the sample data it returns ₹70.00.
Shipping cost per order = Total shipping cost ÷ Number of orders
What you need
Shipping cost per order is what you pay couriers, on average, for each order: total shipping cost in a period divided by the number of orders shipped. You need these columns, here from the sample file monthly.csv:
- Shipping cost: column F (shipping_cost)
- Orders: column N (orders)
Step by step
- Download monthly.csv below and open it: in Excel use File → Open; in Google Sheets use File → Import → Upload. The headers land in row 1 and the six months in rows 2 to 7.
- Click any empty cell and enter =SUM(F2:F7) / SUM(N2:N7) for the whole six months. It adds up each column first and then does the arithmetic once, which is the correct way to combine months.
- For each month, click AQ2, enter =F2 / N2 and drag the fill handle down to row 7.
- Format the results as currency with two decimals.
- If a month can have zero in the denominator, wrap the formula so it shows a blank instead of #DIV/0!: =IFERROR(F2 / N2,"").
The formulas
=SUM(F2:F7) / SUM(N2:N7)=F2 / N2What you should get
Run against the sample data, the code above returns these values:
| Month | shipping_cost | orders | shipping_per_order |
|---|---|---|---|
| 2026-01 | 49,100 | 702 | ₹69.94 |
| 2026-02 | 52,400 | 748 | ₹70.05 |
| 2026-03 | 56,800 | 812 | ₹69.95 |
| 2026-04 | 54,000 | 771 | ₹70.04 |
| 2026-05 | 59,200 | 846 | ₹69.98 |
| 2026-06 | 64,200 | 917 | ₹70.01 |
| Whole period | 3,35,700 | 4,796 | ₹70.00 |
₹3,35,700 ÷ 4,796 = ₹70.00
Notes for Excel
- Google Sheets accepts the same formulas. If your spreadsheet locale uses a comma as the decimal separator, Sheets and Excel expect semicolons between function arguments instead of commas.
- Averaging the monthly results with AVERAGE() gives a different and usually wrong answer for the period, because every month counts the same however large it was.
- Excel tables (Insert → Table) let you write the same formula with column names instead of letters, which is easier to read and survives inserted columns.
Where shipping cost per order misleads
- Include the cost of return and RTO shipments, or the figure looks lower than what you actually paid.
- Shipping charged to customers is revenue, not a reduction of cost. Keep the two apart.
- Courier invoices often arrive weeks late. Match costs to the month the order shipped, not the month the invoice came.
The full explanation, with a calculator, is on the Shipping cost per order page.

About the data on this page
The figures come from a small made-up dataset, printed above in full so you can check every number by hand. Download it as monthly.csv. The results are computed from those rows when the page is built, and the Excel formulas, SQL and Python on these pages are run against the same rows before publishing, so the code and the answers agree.
