How the calculation works
Threshold = (delivery subsidy + desired retained contribution) ÷ pre-delivery contribution rate. The rate must already account for the variable costs other than this subsidy.
Worked example
An ₹80 subsidy plus ₹100 retained contribution at a 40% rate gives ₹450.
Use the result carefully
The result is not a promise that every basket qualifies economically. Low-margin product mixes, remote-area charges and returns need separate checks.
Choose a consistent time period and cost boundary. Keep a note of where each input came from, then compare the scenario with actual results. Money is displayed in rupees to two decimal places; calculation precision and rounding are described above.
Before using this in your business
- Replace every example input with a value you can explain.
- Check that taxes, refunds, shipping, labour and fixed costs are included or excluded deliberately.
- Run a conservative scenario as well as your expected case.
- Do not treat the output as a price quotation, tax advice, credit decision or automatic store setting.
