KiwiSaver Provider Fee Comparison Calculator NZ 2026/27
This calculator compares KiwiSaver providers the way you actually experience the decision: by name, not just by an abstract percentage on a comparison chart. Most people choosing between providers see a list of unfamiliar fund names and fee percentages that look almost identical, 1.05% here, 0.65% there, and it is genuinely hard to tell whether the gap is worth the hassle of switching. This tool turns that percentage gap into an actual dollar figure over the number of years you plan to stay invested. Enter your current KiwiSaver balance and your salary, and the calculator estimates your total annual contribution using the default 3.5% employee rate, the default 3.5% employer rate and the government contribution of 25 cents per dollar up to $260.72 a year, all current settings from 1 April 2026, though you can overwrite the estimate if you know your real figure. Choose a fund type to set the expected long-run return, then name up to three providers you want to compare, your current one and up to two others you are weighing up, along with each one's published annual fee. The calculator projects your balance forward under each provider's fee, holding the assumed investment performance equal across all three, and shows you the projected balance for each and the dollar gap between the cheapest and the most expensive. It updates instantly as you type. This is built for anyone reviewing their KiwiSaver provider, comparing quotes before a switch, or simply wanting to see whether the fee difference between two funds is actually worth acting on.
paye-data.js file.Return assumptions: Conservative/Defensive 2.5% · Balanced 3.5% · Growth 4.5% · Aggressive 5.5% a year, the standard long-run projection figures used in KiwiSaver Fund Updates, net of typical fees and after tax at the 28% prescribed investor rate (PIR), set under the Financial Markets Conduct Regulations 2014.
Method: the first provider's return is treated as the fund-type return you selected. Each other provider's return is that same figure adjusted only by its fee difference from the first provider, so the comparison assumes identical gross investment performance and isolates the effect of fees alone. The starting fee percentages shown for Provider 2 and Provider 3 are illustrative examples only, not published rates for any real company, and must be replaced with the actual fee from that provider's current Fund Update.

| Provider | Annual fee | Net return used | Balance after 30 years |
|---|---|---|---|
| Provider A (my current fund) | 1.05% | 4.50% | $368,394 |
| Provider B | 0.65% | 4.90% | $398,187 |
| Provider C | 0.30% | 5.25% | $426,516 |
This is a projection, not a promise. It assumes a constant average annual return with no market ups and downs, contributions added once a year, and fee and PIR that do not change. It does not include any cost or time out of the market from switching. Check each provider's own Fund Update for its actual current fee and return history.
How this comparison works
KiwiSaver providers each set their own annual fund charge, usually a percentage of your balance, deducted regardless of whether the fund gained or lost value that period. On a small balance the dollar amount looks trivial: 1% of $5,000 is only $50 a year. The problem is that your balance grows over your working life, and the fee grows in dollar terms right along with it, every single year. This calculator starts from your current balance and salary, estimates your annual contribution (or uses one you enter yourself), and then runs the same projection three times, once for each provider you name, changing only the fee. The fund-type return you select (Conservative, Balanced, Growth or Aggressive) is treated as the return your first provider, Provider A, already delivers net of its own fee. Providers B and C then get the same underlying return adjusted only by how much cheaper or more expensive their fee is relative to Provider A. That isolates the one variable you are actually trying to compare: the cost of holding your money with each named provider, assuming they all invest to a similar standard.
Worked example
Take someone on a $65,000 salary with a $20,000 KiwiSaver balance today. Contributing the default 3.5% themselves ($2,275 a year), matched by the default 3.5% from their employer ($2,275 a year), plus the maximum government contribution of $260.72 (since $2,275 of member contributions already clears the $1,042.86 needed), gives a total annual contribution of $4,810.72. They choose a Growth fund, assumed to return 4.5% a year net of fees and tax. Provider A, their current fund, charges 1.05% a year; after 30 years their balance grows to about $368,394. Provider B, an alternative charging 0.65%, a 0.40 percentage point saving, pushes the net return to 4.90% and grows the balance to about $398,187, roughly $29,793 more. Provider C, a lower-cost option charging 0.30%, a 0.75 percentage point saving on Provider A, lifts the net return to 5.25% and grows the balance to about $426,516, a full $58,122 more than staying with Provider A, for exactly the same contributions and, in this comparison, the same underlying investment performance.
Why the gap is bigger than the percentage suggests
A 0.75 percentage point fee gap sounds small next to a headline return of 4.5% or 5.25%. The reason it turns into tens of thousands of dollars is that fees and returns both compound, in opposite directions, over the same balance. Every dollar taken as a fee stops earning a return for every year you have left invested, so the true cost of a fee is not the percentage once, it is that percentage applied to an ever-growing balance for as long as you stay in that fund. Run the same maths over 10 years instead of 30 and the gap shrinks dramatically, because there is far less time for the difference to compound. That is exactly why the time horizon field matters so much in this calculator, and why a fee difference that looks minor to someone in their fifties can be worth tens of thousands of dollars to someone in their twenties.
What this calculator assumes
- Investment returns of 2.5% (Conservative/Defensive), 3.5% (Balanced), 4.5% (Growth) or 5.5% (Aggressive) a year, the standard long-run projection figures used in KiwiSaver Fund Updates, already net of typical fees and after tax at the 28% PIR.
- Provider A's return equals the fund-type figure you select; Providers B and C use that same figure adjusted only by their fee difference from Provider A, so all three are assumed to achieve identical gross investment performance before fees.
- Annual contributions are estimated from your salary using the default 3.5% employee rate, default 3.5% employer rate and the government contribution rules current from 1 April 2026, or you can enter your own known figure instead.
- Contributions are added once a year and compound at the same rate as the rest of the balance, an approximation of a regular pay-cycle contribution.
- The starting fee percentages shown for Provider B and Provider C are illustrative examples, not the published rate of any real KiwiSaver scheme, and should be replaced with the actual figure from that provider's current Fund Update before you rely on the result.
- No cost or time out of the market is assumed for switching. Most KiwiSaver switches in New Zealand are free, but always check with your current provider.
- Results are a projection based on the figures you enter, not a forecast or a promise of future performance, and not personalised financial advice.
Who this calculator is for
This is for anyone with a KiwiSaver account who has been sent a comparison, seen an advert for a lower-fee provider, or simply hasn't checked their own fund's fee in years. It suits people actively shopping between two or three named providers and wanting the dollar answer rather than a page of percentages, as well as anyone choosing between fund types within the same provider, since a Growth fund's higher assumed return and a Conservative fund's lower one will change how much a given fee gap is worth chasing. It is general information to help you compare options, not personalised financial advice, and does not replace reading each provider's own Fund Update.
