Let’s work it out.
The starting figures are illustrations, not industry benchmarks. Replace them with your own costs and assumptions. Calculations happen in your browser; figures are not saved to your account or sent as analytics properties.
Changes the display label only. It does not convert amounts. Use a consistent basis for tax-inclusive or tax-exclusive figures.
Your planning estimate
- Deposit amount
- AUD 360.00
- Remaining balance
- AUD 840.00
- Agreed total
- AUD 1,200.00
How this calculation works
Multiply the agreed total by the deposit percentage and round the deposit to two decimal places. Subtract that rounded deposit from the two-decimal total for the remaining balance. The calculator does not determine what deposit is permitted or appropriate for your agreement.
A little more context: Think through a deposit arrangement.

A worked example you can change
The tool starts with the illustrative figures below. They demonstrate the calculation; they are not industry averages, recommended rates or promises about what you will earn. All monetary figures in this example are AUD.
Agreed total to split: 1200 AUD Deposit percentage: 30% Deposit amount: 360 AUD Remaining balance: 840 AUD Agreed total: 1,200 AUD
Make the estimate fit your business work
The most useful estimate is one you can explain. Check these details against the actual job or business arrangement before you rely on the result.
- Agree the payment schedule and any cancellation or refund terms before work starts.
- Deduct a deposit already paid when presenting the final balance.
- This tool only splits the total entered. It does not calculate tax treatment, payment due dates or contractual requirements.
What this tool does and does not include
The calculation uses the figures you enter and the method above. It does not fetch market rates, convert currencies, assess demand or calculate tax, payroll or legal obligations. Choose a consistent tax basis for the amounts you enter. Changing display currency changes the label only.
Your inputs stay in this browser page and reset when you leave or reload. You can copy or download a text estimate with its assumptions. If you choose to use Lufu, you can then prepare an actual quote or invoice with the details you have agreed.
