METHOD & GUIDANCE
How this calculation works
Enter figures from the same period and on a consistent sales tax-inclusive or sales tax-exclusive basis. Tool IQ recalculates every output immediately; nothing you enter is saved or sent to us.
How to use the result
Use the recommended price as a floor under the stated assumptions, then test fees, overhead and rounding before publishing a customer price.
Worked example
The opening inputs combine 65 of unit cost with 3% fees and a 35% target margin to calculate the price needed to preserve both.
Common mistakes
- Setting target margin plus percentage fees at 100% or more.
- Leaving per-sale overhead out.
- Rounding down and silently missing the target.
Frequently asked questions
Is this calculator free?
Yes. It requires no account and stores no calculation inputs.
Can I use the answer for a formal filing?
No. It is a planning estimate, not accounting, tax, legal or investment advice. Confirm material decisions with a qualified professional.
Should I include sales tax?
Use a consistent basis throughout. Businesses that recover input tax commonly model net figures; consumer-facing prices are often considered gross.
