Three salaries after tax and a two-bedroom house
These one-earner examples use the 1 April 2026–31 March 2027 income-tax and ACC basis. They assume no tax credits or other payroll deductions. Housing uses the same home category in each named area, from 1 March–31 August 2026.
| Gross salary / year | After tax + ACC / month | After Avondale rent / month | After Karori rent / month | After Riccarton rent / month |
|---|---|---|---|---|
| $80,000.00 | $5,193.54 | $2,680.21 | $2,723.54 | $3,113.54 |
| $100,000.00 | $6,281.04 | $3,767.71 | $3,811.04 | $4,201.04 |
| $120,000.00 | $7,368.54 | $4,855.21 | $4,898.54 | $5,288.54 |
Weekly median rents: Avondale NZ$580; Karori NZ$570; Riccarton NZ$480. Food, power, travel, care, debt payments and saving must still come from the amount left. These three areas do not represent their whole cities.
Compare one earner with two at the same household gross
Income tax is calculated for each person. Here the two earners receive equal salaries. Both calculations exclude credits and other payroll deductions; additional travel or care costs are still to be considered.
| Household gross | One earner | Two equal earners | Difference / year |
|---|---|---|---|
| $80,000.00 | $62,322.50 | $66,784.00 ($40,000.00 gross each) | $4,461.50 |
| $100,000.00 | $75,372.50 | $82,934.00 ($50,000.00 gross each) | $7,561.50 |
| $120,000.00 | $88,422.50 | $97,459.00 ($60,000.00 gross each) | $9,036.50 |

Try your income and rent
Enter one income first. Add a second earner or other household costs when useful. All amounts are NZD. A blank stays unknown; use 0 for an amount that does not apply. Your entries stay in this browser tab until you save a file or transfer a figure.
Carry the figures into your household budget
Income and rent transfer separately. The household budget shows the proposed change before you apply it and keeps your other entries. Annual estimates stay annual; confirm an actual pay packet and first payday in the household budget before using pay in the moving budget.
For two earners, keep their actual payment dates separate in the moving budget. Its regular-pay fields can hold one payment stream; use dated extra-income rows for the other.
A NZ$100,000 salary leaves NZ$3,768 a month after the Avondale rent example
For one person earning NZ$100,000 over a full year, the 2026/27 example deducts NZ$22,877.50 income tax and NZ$1,750 ACC earners’ levy. That leaves NZ$75,372.50 a year, or NZ$6,281.04 per average month, before other payroll deductions and without tax credits.
The March–August 2026 median for a two-bedroom house in the named Avondale area is NZ$580 a week. Over 52 weeks that is NZ$30,160, averaging NZ$2,513.33 a month. Subtracting that rent leaves NZ$3,767.71 per average month for the household’s other costs.
Food, power, water, internet, transport and care must come from that amount, along with any insurance, loan repayments, remittances and saving you need. Build those amounts from your household’s routines and quotes. The household budget provides two worked Avondale examples and editable spending lines.
Two earners can have different take-home income at the same household salary
Two people earning NZ$50,000 each have the same NZ$100,000 household gross as one person earning NZ$100,000. Income tax is applied to each person’s income separately. With the same no-credit, no-other-deduction assumptions, the two earners have NZ$82,934 after income tax and ACC, compared with NZ$75,372.50 for the single earner: NZ$7,561.50 more over the year, or about NZ$630 per average month.
The spending side can change too. Two jobs may need a second commute, more childcare or different working hours. Enter those costs before deciding whether the difference improves your household budget. Keep the salaries separate in the calculator; adding them together as one person’s income would change the tax calculation. The take-home-pay guide explains how the bands and deductions work.
Compare the same home type before comparing locations
The main table uses two-bedroom houses in all three areas. Its Riccarton median is NZ$100 a week below Avondale’s, which leaves NZ$5,200 more over 52 weeks, or NZ$433.33 per average month, if income and other costs stay the same.
That is a comparison of recorded rents for two named local areas. The homes differ in location, condition, amenities and transport access. A move can also change income and other spending. Use a property quote when you have one, and check the commute and move-in date alongside its rent.
The optional selector also includes three-bedroom houses and one- or two-bedroom apartments. Each amount is for the whole property. If you will share a home, enter your actual share and the bills you will pay; dividing a whole-property median by its bedroom count does not establish the price of a room.
See all twelve local rent references for their ranges and monthly equivalents. A recorded median is a starting budget figure, not an available home you can book.
Use your actual pay when the offer becomes a payroll amount
Choose actual take-home payments when payroll has confirmed the amount or you have a representative payslip. Enter the payment after deductions and its frequency. The calculator annualises it for a steady-income comparison and does not deduct tax or ACC again.
Keep a one-off bonus, reimbursement or unusually short pay period separate from normal recurring pay. If your regular amount varies, use a clearly chosen scenario and test a lower one as well. A full-year salary estimate cannot establish the tax outcome for your arrival year or account for every tax code and personal circumstance.
Saving the comparison retains its entered amounts, source notes and 2026/27 calculation version. Opening it requires confirmation before replacing the current inputs. If the calculation version changes in a future release, the old file must be reviewed rather than silently recomputed with new rules.
Put the first payment on the date it will arrive
Monthly affordability and arrival cash need separate checks. You may be able to cover the regular rent but still need money for a bond, advance rent, temporary accommodation and setup before the first salary arrives.
Use the comparison’s transfer buttons to preview income or rent separately in your household budget. Existing spending lines stay in place. An annual salary estimate transfers as an annual planning amount; it cannot become a regular payment in the moving budget without an actual payment amount, period, first payday and your confirmation.
For two earners, record each pay schedule separately. The moving budget can hold one regular-pay schedule and dated extra-income entries for the second. Check any partial first payment with payroll. The upfront rental payment calculator helps put the tenancy payments on their own dates.
Does the amount left after rent show how much I can save?
No. Income after rent still has to cover the rest of your household spending. Enter food, bills, travel, care, debt and other commitments, allow for irregular costs, then decide how much to reserve or save. The optional other-cost field includes only the amount you enter; a blank remains unknown.
Can I use these figures for Auckland, Wellington or Christchurch as a whole?
No. The rental observations cover the named Tenancy Services areas of Avondale, Karori and Riccarton for March–August 2026. For another neighbourhood, use the official market-rent lookup with the same home type and bedroom count, then replace it with a suitable property quote.
