Add sales tax to a net price or separate the tax component from a tax-exclusive amount. Use current figures from your seller dashboard, supplier quotation, courier tariff or payment statement. Every major assumption stays editable because platform terms, return rates, taxes and business costs differ by seller and can change.
How to use it
- 1
Use current values from your store dashboard, supplier invoice, courier tariff or payment statement.
- 2
Include costs that occur outside the marketplace, such as packaging, returns, advertising and withdrawal charges.
- 3
Test a conservative scenario before changing prices, stocking inventory or committing cash.
Formula and methodology
Tax = net amount × sales-tax rate; gross amount = net amount + tax.
Calculates revenue, cost and profit from the commercial assumptions entered. Reconcile results with current platform, courier, payment and tax statements.
Worked calculation example
PKR 10,000 at an entered 18% rate produces PKR 1,800 tax and PKR 11,800 gross.
How to interpret your result
Use the calculation to separate net price and tax, then confirm whether the transaction and supplier are subject to that treatment.
Input guide
Enter the tax-exclusive base only when the invoice is quoted net.
Use the current applicable rate and classification.
Keep exempt, zero-rated and taxable supplies separate.
Scenario comparison
| Scenario | What it demonstrates |
|---|---|
| PKR 10,000 at 18% | PKR 1,800 tax and PKR 11,800 gross. |
| Tax-inclusive quotation | first remove tax rather than adding it again. |
| Mixed invoice | calculate taxable lines separately. |
Common mistakes to avoid
- Adding tax to a price that already includes it.
- Assuming the standard rate applies to every supply.
- Treating a calculator result as a valid tax invoice.
Confirm registration, classification and rate using current FBR material or professional advice.
What can affect the result?
Changing commercial terms
Marketplace commissions, payment fees, courier tariffs and exchange rates can change without matching older examples.
Returns and timing
COD failures, refunds, settlement delays and inventory lead times affect cash differently from accounting profit.
Tax and records
Keep invoices and reconcile the estimate with current tax, customs and platform documentation.
Limits of this estimate
This planning model simplifies commercial operations and cannot confirm platform invoices, tax registration, customs classification, courier surcharges, refund behaviour or future exchange rates.
