Net = Gross / (1 + Tax%)About this tool
In North America, software prices are almost universally displayed as tax-exclusive (e.g. $50/mo plus applicable state sales tax calculated at checkout). However, in the European Union, United Kingdom, Australia, and many other international jurisdictions, consumer protection regulations mandate that published retail prices must be tax-inclusive, displaying the final amount the customer will pay including VAT or GST. If you sell a subscription in the UK for £60 inclusive of 20% VAT, your company does not keep £60—you must extract the 20% tax component (£10) and remit it to HMRC, leaving your business with a net base revenue of £50. Failing to compute reverse tax formulas accurately distorts MRR reporting and leaves companies with unexpected tax liabilities. Use this tool to extract net base prices from gross inclusive figures.
How It Works
- 1Input the total gross tax-inclusive price charged to the customer.
- 2Input the applicable statutory tax rate percentage (e.g. 20% for UK VAT, 18% for India GST, 10% for Australia GST).
- 3Inspect the calculated net base price, the exact tax dollar amount to remit, and the effective tax fraction.
Formula & Math
Transparent LogicNet Base Price = Gross Price / (1 + (Tax Rate% / 100)); Tax Amount = Gross Price - Net Base Price
Worked Practical Example
A European customer pays €120/year tax-inclusive for a tool in a country with 20% VAT.
Calculation / Steps
Net Base = €120 / (1 + 0.20) = €120 / 1.20 = €100.00. Tax Amount = €120 - €100 = €20.00.
Expected Result
€100.00 net base revenue recognized; €20.00 VAT remitted to tax authorities.
Frequently Asked Questions
Why can't I just subtract 20% from €120 to find the tax?+
Because 20% of €120 is €24, which would leave €96. But €96 plus 20% tax is only €115.20, not €120. Tax is calculated on top of the net base, not backwards from the gross.
Should B2B SaaS display tax-inclusive or tax-exclusive prices?+
Business buyers usually expect tax-exclusive prices because they can often reclaim VAT, while many consumer markets expect the final price to include tax. If you sell to both, say which one applies and calculate tax at checkout from the buyer's location.
