Calculation breakdown
- Cost
- (100h × $100.00 + $2,000.00) × (1 + 10%) = $13,200.00
- Price before GST
- $13,200.00 ÷ (1 − 20%) = $16,500.00
- Price including GST
- $16,500.00 × 1.10 = $18,150.00
Assumptions
- Margin is applied on top of total cost (cost ÷ (1 − margin)), not as a simple markup.
- GST is added at 10% only when you indicate you are registered for GST.
- Contingency covers scope creep and unplanned costs and is applied before the margin calculation.

How this calculator works
Enter your estimated hours, hourly rate, fixed expenses and a contingency buffer, then set your target profit margin to calculate the price you should quote before and after GST, so your project stays profitable even if scope shifts slightly.

Frequently asked questions
Why apply margin as cost ÷ (1 − margin) instead of a simple markup?
This ensures the stated margin percentage is the actual profit share of the final price, rather than a markup on cost which understates true margin.
Should I always add contingency?
A 10–20% contingency is common for fixed-price freelance work to absorb scope creep or underestimated hours.
Do I need to add GST?
Only if you are registered for GST — turn on the toggle to add 10% GST to your quoted price.
