Keep selling price, direct costs, overhead and cash collection separate when planning a small shop, home business or service. Revenue and cash received are not always the same.

Distinguish margin from markup
Choose whether a percentage is based on selling price or cost before using it. Include the product’s relevant variable costs, such as packaging or a transaction fee. Do not describe contribution as net profit when rent, labour or other costs remain outside the calculation.
Worksheet: Markup = (price − cost) ÷ cost; margin = (price − cost) ÷ price.
Example: distinguish margin from markup
A product costing PKR 80 and sold at PKR 100 has PKR 20 contribution, 25% markup and 20% margin before omitted costs. The percentages differ because their denominators differ.
Track stock, overhead and credit sales
Record goods used or sold separately from goods bought for future sale. Keep customer credit or udhaar outstanding until cash is received. Allocate shared overhead consistently and document what the allocation includes. Do not enter an assumed tax rate without verifying applicability.
Worksheet: Break-even units = fixed costs ÷ positive contribution per unit, rounded up.
Example: track stock, overhead and credit sales
With PKR 5,000 fixed costs and PKR 50 contribution per unit, 100 units cover those fixed costs. This simplified model assumes one stable product mix, price and variable cost.
Prepare your inputs before comparing results
- Choose one task and one planning period.
- Record the measurement units and the source and date of each quotation.
- Separate quantities used, quantities purchased and any remainder.
- List costs included in the estimate and costs excluded from it.
- Recheck the result when quantities, prices or circumstances change.
