One of the hardest parts of going freelance or contracting in New Zealand is deciding what to charge. Set your rate too low and you will work yourself into the ground for very little. Set it without thinking it through and you might find that, after tax, expenses, and unpaid time, you are earning less than you did as an employee. The trick is to build your rate from the ground up rather than plucking a number out of the air.
This guide walks through a simple, honest method for working out a day rate that actually pays the bills, covers your tax, and leaves room for a profit. It is written for 2026, with current tax and cost realities in mind.
Why Your Day Rate Is Not Just Your Old Salary Divided by Days
A common mistake is to take your old annual salary, divide it by the roughly 260 working days in a year, and call that your day rate. The problem is that a salary comes bundled with things you no longer get as a freelancer: paid annual leave, sick leave, public holidays, KiwiSaver employer contributions, and ACC cover paid partly by your employer.
As a freelancer, you have to fund all of that yourself out of your rate. You also have gaps between contracts, admin time you cannot bill for, and business expenses. So your day rate needs to be meaningfully higher than your old salary divided by working days, just to break even.
Step One: Work Out Your Real Billable Days
There are about 260 weekdays in a year, but you will not bill all of them. Take off four weeks of holiday, public holidays, a buffer for sick days, and time spent on marketing, quotes, invoicing, and admin. Many freelancers find they can realistically bill somewhere between 180 and 210 days a year, not 260.
This matters enormously. If you assume 260 billable days but only manage 190, your effective rate is far lower than you planned. Be conservative here. It is better to be pleasantly surprised than to run out of money.
Step Two: Add Up What You Actually Need to Earn
Start with the income you want to take home for yourself. Then add the costs of running your business: software, insurance, equipment, phone and internet, accounting, and any subscriptions. Do not forget to set aside money for your own KiwiSaver and an ACC levy, since nobody is paying these for you anymore.
To see how your business income translates into take-home pay after tax, our contractor calculator is a good starting point. It accounts for the deductions a contractor faces so you can see the real picture rather than a gross figure.
Step Three: Build In Tax
This is where many freelancers come unstuck. The money a client pays you is not all yours. You have to pay income tax on your profit, and if your turnover is over $60,000, you also have to handle GST. A sensible habit is to set aside roughly 25 to 30 percent of every payment for tax, in a separate account, the moment it arrives.
Our self-employed tax calculator helps you estimate your income tax so you know how much to put aside. If you are registered for GST, the GST calculator shows you the GST portion of your invoices so you do not accidentally spend money that belongs to IRD.
Step Four: Turn It All Into a Day Rate
Once you know your target income, your business costs, your tax set-aside, and your realistic billable days, the maths becomes simple. Add up everything you need to earn across the year, then divide it by your billable days. That gives you the day rate you need just to hit your goal.
Our day rate calculator does this calculation for you and lets you test different scenarios. Want to know what happens if you only bill 180 days instead of 200? Or if you want to take home an extra $10,000? Change the inputs and watch the rate move. If you prefer to think in shorter chunks, the freelancer rate calculator helps you set hourly and project pricing too.
Step Five: Sense-Check Against the Market
Your calculated rate tells you what you need. The market tells you what is realistic. Talk to other freelancers in your field, look at job boards, and ask recruiters what contractors in your area are charging. If your calculated rate is wildly above the market, you may need to either sharpen your value proposition or look at trimming costs. If it is below the market, you are probably undercharging.
One useful exercise is to compare your freelance rate to what you would earn as a permanent employee. Our salary comparison calculator helps you weigh a contract rate against a salary so you can decide whether the freelance premium is worth the extra risk and admin.
Common Mistakes to Avoid
- Forgetting GST. If you are registered, your headline rate should make clear whether it includes GST or not. Confusion here can cost you a chunk of every invoice.
- Ignoring slow periods. Contracts end, clients pause projects, and summer can be quiet. Your rate needs to cover the lean times.
- Never raising your rate. Your costs rise every year. If your rate stays flat, you are quietly taking a pay cut. Review it annually.
- Underpricing to win work. A cheap rate attracts clients who value you cheaply. It is usually better to charge fairly and deliver well.
The Bottom Line
A good freelance day rate is built, not guessed. Start with your realistic billable days, add up your target income and business costs, build in tax and GST, then divide to get your rate. Sense-check it against the market and review it every year. Get this right and freelancing in New Zealand can pay better than employment while giving you the freedom you went freelance for in the first place. Get it wrong and you will work harder for less, so it is well worth taking the time to do the sums properly.
