Free KiwiSaver Fees Calculator for New Zealanders
A 1% annual fee can cost tens of thousands over a working life. The calculator shows total fees paid plus the compounding growth lost compared to a lower-fee alternative.

About our KiwiSaver Fees Calculator
Fee dragFee dragCumulative effect of fund fees eating into investment returns over time.View in glossary → is the missing balance at retirement attributable to KiwiSaver fund fees. A 1% fee on a fund returning 6% leaves the investor with 5%; compounded over 35 years, the missing 1% per year cuts the final balance by roughly 25%.
The calculator runs the same compound-growth maths twice: once at the assumed gross return, once at the gross return minus the annual fee. The dollar gap is the fee drag, expressed as both a percentage of final balance and an absolute lost-balance figure.
NZ KiwiSaver fees range from around 0.4% (low-fee index funds) to 2%+ (boutique active funds). The default-fund providers sit in the middle at 0.5-0.7%. The FMA’s annual KiwiSaver report publishes the audited fee figures by category.
How to use it
Enter your current balance, monthly contribution, expected gross return rate, your fund’s annual fee, and the years to retirement. The "annual fund charge" figure on the fund’s Product Disclosure Statement is the right input.
Toggle between current and target fee to see the difference in compounded balance. The calculator also shows total fees paid in dollars over the period.
Why use it
The decision to switch KiwiSaver providers is usually driven by fees. The calculator surfaces the dollar value of the switch over the remaining horizon. For a younger member with 30+ years to retirement, even a 0.3% fee saving compounds to a meaningful figure.
For older members close to retirement, the fee impact is smaller because there are fewer years for the differential to compound. A 50-year-old with 15 years to retirement saves much less in absolute dollars than a 30-year-old with 35 years, even if the percentage fee saving is identical.
The maths behind it
Fee drag = FV at gross return − FV at (gross − fee) return The calculator runs the future-value formula twice: once at the assumed gross return rate, once at the gross rate minus the annual fee. The gap is the fee drag, the missing balance at retirement attributable to fees compounding alongside returns. A 1% fee on a fund returning 6% leaves the investor with 5%, which compounds noticeably less over 30+ years. The dollar effect is non-linear: longer horizons amplify the drag.
Worked example
Cassie, designer in Masterton, age 30 with $35,000 KiwiSaver and a 1.05% annual fee.
Cassie’s current KiwiSaver fund charges 1.05% a year on balance, including the management fee, member fee, and underlying fund costs. Her balance is $35,000, salary $78,000, contributing 4%. Returns averaged 6.5% before fees over the last decade.
Over 35 years to age 65 at 5.45% net return (6.5% − 1.05%), her balance reaches roughly $720,000. At a 0.45% fee fund (typical for index-style KiwiSaver schemes), the same horizon and 6.5% gross return produces $895,000.
Switching to the lower-fee fund saves $175,000 at retirement, around 24% more balance. The additional fees compound against her every year; the saved fees compound for her every year.
Two-thirds of NZ KiwiSaver funds charge fees in the 0.6%-1.2% range; the highest sit above 2%, the lowest below 0.4%. The FMA’s annual KiwiSaver report publishes fee bands by fund category.
Things to keep in mind
- Fee comparison is hard. KiwiSaver fees come in multiple layers: management fee, performance fee, member fee (a flat $20-$50/year), and underlying fund costs. Some providers disclose the total expense ratio (TER) as a single figure; others split the layers. The "annual fund charge" or "total annual fund charge" on the disclosure document is the figure to compare.
- Higher fees do not buy higher returns. FMA research shows no consistent relationship between fee level and net return in NZ KiwiSaver. Active funds charging 1.2-1.5% have not, on average, beaten low-fee passive funds at 0.4-0.6%. The default-fund providers tend to sit in the middle.
- Returns vary year to year. The calculator assumes a constant return rate. Real returns swing from -10% to +25% in single years even within the same fund. The fee, by contrast, is consistent every year. Over 30+ years the average return tends toward the long-run figure; the fee compounds linearly.
- Fund switching has timing risks. Switching between funds typically takes 5-10 business days, during which your balance is in cash. In a strongly rising market, switching captures a small "out of market" loss. In a falling market, the same switch saves a small loss. The effect is usually well under 1% of balance.
- Fees are not the only quality factor. Customer service, online tools, ethical investment options, and historical fund performance under different market conditions all matter alongside fees. A fund with a 0.4% fee but poor service may not be the right fit for someone who values phone-based support.
NZ-specific notes
FAQs
Which fee figure should I compare?
The "total annual fund charge" or "fund charges" disclosed in the fund’s Product Disclosure Statement, including management fee, performance fee, and underlying fund costs, but not the member fee (which is a flat dollar amount). The Sorted fund finder shows the comparable figure for every NZ KiwiSaver scheme.
What is a typical KiwiSaver fee?
Default funds (the schemes you’re placed in if you do not actively choose) sit at 0.5-0.7%. Index-based growth and balanced funds typically run 0.4-0.6%. Active funds run 0.8-1.2%. Premium boutique funds and ethical funds can charge 1.5%+.
How much do fees actually cost over 30 years?
A 1% fee on a 30-year horizon at 6% gross return reduces the final balance by roughly 25%. A 0.5% fee reduces it by about 13%. The compounding effect of fees grows non-linearly with time, which is why the difference between 0.5% and 1.0% becomes substantial over a working life.
Can I switch providers?
Yes, anytime, no fee. The new provider handles the transfer; it usually takes 5-10 business days. You can also switch funds within the same provider (e.g., from balanced to growth). Switching does not affect the employer or government contributions.
Do all funds charge the same way?
No. Fee structures vary: some charge a flat percentage on balance, some charge tiered fees (different rates at different balance bands), some charge a performance fee on top of a base management fee. Performance fees apply only when the fund beats a benchmark, but can add 0.2-0.5% to total cost in good years.
Are low-fee funds better?
On average, yes, after fees. FMA research has not found consistent evidence that higher-fee funds in NZ produce higher net returns over time. Other factors (service, ethical screening, customer experience) may justify a higher-fee fund for individual investors, but pure return-chasing usually points toward lower fees.
