Useful next calculations
When to use this calculator
- Before pricing a job, setting margin targets or reviewing hiring costs.

- When you need a practical estimate before committing to a budget or proposal.
- When you are modelling break-even volume as costs or prices change.
A worked example
These are the example figures the calculator opens with.
| Input | Value |
|---|---|
| Cost Price (NZ$) | NZ$50 |
| Markup (%) | 30% |
For those figures the calculator returns:
- Selling price: NZ$65.00
- Cost price: NZ$50.00
- Markup amount: NZ$15.00
- Gross margin: 23.08%
Common mistakes
- Using an assumption that is not supported by a current local quote, bill, statement or official source.
- Treating a generic estimate as a lender, provider, payroll or tax authority decision.
- Mixing monthly and annual inputs without converting them consistently.
- Testing only one scenario instead of checking how a cautious assumption changes the result.
What to do next
- Run a second scenario with a cautious assumption so you can see the downside clearly.
- Compare the result with the related calculators below before making a decision.
- Check current local rules, eligibility and provider terms before applying or committing money.
- Keep a record of the assumptions so you can update the estimate when a quote, bill or pay figure changes.

Markup is the percentage added to cost price to get the selling price, while margin is the percentage of the selling price that is profit. A 50% markup equals a 33.3% margin.
