Contractor Day Rate Calculator

A day rate has to cover everything a salary package delivers alongside the salary itself: employer super, paid annual leave, personal leave and public holidays, business overheads, and the days you are not billing. The calculator builds billable capacity from weekdays less leave, holidays and non-billable days, multiplied by your utilisation, then spreads target income, super replacement, overheads and your chosen margin across that smaller number of days. This is why the day rate lands well above a salary divided by working days.

Enter the annual income you want to end up with as your target, add your annual overheads, super replacement percentage and margin, then set the leave, holidays and utilisation that describe your year. The calculator divides the total amount to be recovered by the billable days that remain, producing the day rate and the equivalent hourly rate. To see what a comparable salary leaves after tax, use the take-home pay calculator.

Utilisation is the share of your available working days that you actually bill, after allowing for business development, admin, training and gaps between engagements. It matters because it divides the same annual cost base across fewer days: a rate priced at full utilisation leaves nothing to absorb an unbilled week. The calculator makes utilisation an explicit input and shows the day rate at points either side of your figure so the sensitivity is visible.

Independent contractors generally fund their own retirement saving out of the rate rather than receiving employer contributions, and some contracting arrangements are treated as employment for superannuation guarantee purposes depending on the terms of the contract. The calculator therefore includes an editable super replacement percentage so the rate carries an equivalent amount rather than assuming it away. Whether your arrangement attracts a superannuation guarantee obligation is a question about your contract and the law, not something the calculator determines.

No. Where you are registered, GST is quoted on top of the rate and is never treated as your revenue, because it is collected on behalf of the Australian Taxation Office. Switching the GST registered toggle adds the current rate from the active GST rule pack to the quoted figure while leaving the underlying rate unchanged. The GST calculator shows the registration turnover thresholds and the arithmetic in full.

Income tax, business structure choices, professional indemnity and public liability insurance premiums, workers compensation and personal services income rules are outside this calculation, which the limitations panel states. Overheads are whatever annual figure you enter, so anything you leave out of that number is absent from the rate. The result is a pricing calculation, not a tax position.

Generally yes. Both come out of the rate, because there is no employer withholding tax each payday and no employer super guarantee contribution unless the contract is one the guarantee treats as employment. Income tax on business profit is assessed at individual marginal rates and is typically prepaid through PAYG instalments, then settled when the return is lodged, and retirement saving comes from personal contributions paid into a fund. The pay calculator has a sole-trader mode that shows the annual tax position on business profit.
