Gross, employee rate, optional voluntary (2026/27)
Employee and employer CEC are modelled as percentages of this gross.
Default 3.5% from 1 Apr 2026. Opt-out (0%) zeroes employer CEC (contributing membership required). Voluntary personal extras can still count toward the government contribution.
Counts toward the government match with employee contributions. About $1,042.86 personal unlocks the full $260.72 credit.
CEC default 3.5% when contributing. Government year is 1 Jul–30 Jun. Does not model fund growth, fees, or first-home withdrawal.

Default employee / CEC 3.5%
Employee, employer CEC after ESCT, and government contribution.
Employee KiwiSaver, compulsory employer contributions (CEC), Employer Superannuation Contribution Tax (ESCT), and the government contribution above come from the gross salary, employee rate, optional voluntary personal contributions, and advanced eligibility / ESCT fields you enter — not a live IRD feed. Rates match published IRD 2026/27 guidance (employee and CEC defaults from 1 Apr 2026). Below are the formulas, steps, and worked examples from the same engine as the live calculator.
Worked example — $100,000 gross
Gross $100,000 @ 3.5% employee / CEC
| Gross salary | $100,000 |
| Employee contribution | $3,500.00 |
| Employer CEC (gross) | $3,500.00 |
| ESCT | $1,155.00 |
| Employer net into fund | $2,345.00 |
| Government contribution | $260.72 |
| Total into account | $6,105.72 |
$100,000 × 3.5% = $3,500.00 employee; employer net $2,345.00; gov $260.72; total $6,105.72
Worked example — partial government contribution
Gross $25,000 — partial government contribution
| Gross salary | $25,000 |
| Personal for gov | $875.00 |
| Government | $218.75 |
| ESCT | $153.13 |
| Employer net | $721.87 |
Personal $875.00; gov $218.75 (short of full $260.72); ESCT $153.13
Income cap illustration
Gov $0.00 (income disqualified); employee $7,000.00; employer net $4,690.00; total $11,690.00
Formulas
- Employee contribution: Employee = Gross × employee rate (default 3.5%)
- Personal contributions for government match: Personal = Employee + voluntary personal (employer CEC does not count)
- Employer CEC (gross): Employer gross = Gross × CEC rate (default 3.5%) when employee rate > 0
- ESCT: ESCT = Employer gross × ESCT rate (from IRD brackets on ESCT income base)
- Employer net into fund: Employer net = Employer gross − ESCT (when ESCT included)
- Government contribution: Gov = min($260.72, Personal × 25%) when eligible and taxable income ≤ $180,000
- Total into account: Total = Employee + Employer net + Government
- Rounding: All NZD amounts rounded to the nearest cent (2 decimal places)

Calculation steps
- Start with annual gross salaryGross salary (NZD annual)
Employee and employer KiwiSaver contributions are modelled as percentages of this gross. Use your contracted annual salary or a clear proxy.
- Apply the employee contribution rateDefault 3.5% from 1 Apr 2026; IRD also supports 3%, 4%, 6%, 8%, 10%, or opt-out (0%)
Opting out (0%) zeroes employee and employer CEC in this model because CEC requires contributing membership. Voluntary personal contributions can still count toward the government contribution if you are otherwise eligible.
- Compute compulsory employer contributionCEC = Gross × 3.5% when employee is contributing
Employer CEC is modelled only when the employee rate is greater than zero. Optional override of the employer rate is available in advanced inputs.
- Deduct ESCT from employer CECESCT rate from IRD brackets on the ESCT income base (defaults to gross)
IRD determines ESCT using prior-year salary plus employer contributions, or an estimate for new employees. This tool uses a simplified income-base proxy.
- Estimate the government contribution25c per $1 of personal contributions, capped at $260.72; income cap $180,000
Government contribution year runs 1 July–30 June (not the tax year). Employer CEC does not count as personal contributions toward the match.
- Sum amounts into the KiwiSaver accountEmployee + employer net (after ESCT) + government
Fund growth, fees, first-home withdrawal, and savings suspension are not modelled.
Key takeaways — KiwiSaver New Zealand
- Default employee and compulsory employer contribution rates are 3.5% of gross from 1 Apr 2026 (IRD 2026/27).
- Government contribution is 25c per $1 of personal contributions, capped at $260.72 — about $1,042.86 personal to get the full credit.
- Taxable income over $180,000 → no government contribution.
- Example: $100,000 @ 3.5% → employee $3,500.00, employer net $2,345.00, gov $260.72, total $6,105.72.
- Example: $50,000 @ 3.5% → full gov $260.72; ESCT $306.25 at 17.5%.
Employee, employer CEC, and government contribution
Same engine as the live calculator. Example at 3.5%: $100,000 × 3.5% = $3,500.00 employee; employer net $2,345.00; gov $260.72; total $6,105.72
Employee = Gross × 3.5%
$100,000 → $3,500.00
Employer net = (Gross × 3.5%) − ESCT
At $100,000: employer net $2,345.00 (ESCT $1,155.00)
Gov = min($260.72, Personal × 25%)
At $100,000 @ 3.5%: gov $260.72
What is KiwiSaver?
KiwiSaver is New Zealand’s voluntary workplace savings scheme. Employees contribute a chosen percentage of gross pay; employers generally pay a compulsory employer contribution (CEC) when you are a contributing member. For 2026/27 the default employee and CEC rates are 3.5% from 1 Apr 2026 (IRD).
At $100,000 gross with the default 3.5% employee rate, employee contributions are $3,500.00 before any voluntary extras.
Employer CEC and ESCT
When you contribute, employers generally pay CEC at 3.5% of gross (IRD from 1 Apr 2026). Employer Superannuation Contribution Tax (ESCT) is deducted from that CEC before it reaches your KiwiSaver account.
ESCT rates follow IRD brackets on an income base. This calculator defaults the ESCT base to your gross salary as a simplified proxy — IRD uses prior-year salary plus employer contributions, or an estimate for new employees.
Government contribution (member tax credit)
IRD pays 25c for every $1 of your personal contributions (employee + voluntary), up to $260.72 per contribution year (1 July–30 June). You need about $1,042.86 of personal contributions to receive the full credit.
If taxable income is over $180,000, no government contribution applies. Example: $200,000 gross → government $0.00 in this model. Employer CEC does not count toward the match.
Opting out of employee contributions
Choosing 0% (payroll opted out) means no employee deduction and no employer CEC in this model — compulsory employer contributions require contributing membership. Voluntary personal contributions to Inland Revenue or your provider can still count toward the government contribution.
Use the New Zealand paycheck calculator to see how a non-zero employee rate reduces take-home cash while building your KiwiSaver balance.
How this compares to Australian Super Guarantee
Australian Super Guarantee is a mandatory employer contribution on ordinary time earnings. KiwiSaver employee rates are chosen (with a 3.5% default from 1 Apr 2026), and employer CEC applies when you are contributing.

Myths vs facts
Myth: Employer CEC counts toward the government contribution.
Only personal contributions (employee rate plus voluntary) count. Employer CEC does not increase the government match in this model.
Myth: I always get $260.72 government contribution at any salary.
You need about $1,042.86 of personal contributions, and taxable income must not exceed $180,000. At $25,000 @ 3.5%, gov is $218.75 — not the full credit.
Myth: Opting out still leaves employer CEC in the fund.
Compulsory employer contributions require contributing membership. At 0% employee, this model sets employer CEC and ESCT to zero. Voluntary personal contributions can still attract a government contribution if you are otherwise eligible.
Myth: ESCT is paid by the employee from take-home pay.
ESCT is deducted from the employer’s CEC before it reaches your KiwiSaver account. Your employee contribution still reduces take-home cash separately.

Common KiwiSaver planning mistakes
Who this helps
Checklist before you change your rate
- Confirm annual gross salary (or a clear proxy) before modelling contributions.
- Choose an IRD employee rate (3.5% default from 1 Apr 2026, or opt-out).
- Add voluntary personal contributions if you are topping up toward $1,042.86 for the full government credit.
- If income approaches $180,000, check government eligibility separately from CEC.
- Remember ESCT income base is simplified — confirm payroll ESCT with your employer or IRD.
- Do not treat this as advice on fund choice, fees, first-home withdrawal, or savings suspension.
- Confirm rates on IRD KiwiSaver and ESCT pages for your year.
