How KiwiSaver fees affect your balance NZ

Discover how KiwiSaver fees compound over decades and why switching to a low-fee fund could boost your retirement savings by thousands of dollars.

Why KiwiSaver fees matter more than you think

KiwiSaver fees seem small on an annual basis—perhaps 1-2 percent of your balance each year. Over 40 years of saving, however, those tiny annual deductions compound into life-changing amounts of money. A difference of just 0.5% in annual fees could cost you tens of thousands of dollars by retirement.

This isn't a minor issue. Fee differences are the single largest controllable factor affecting your retirement balance. Unlike market returns, which you cannot control, you can absolutely control which fund you choose and how much you pay in fees. Understanding the impact of fees and acting on that knowledge could be one of the best financial decisions you ever make.

How KiwiSaver fees work

KiwiSaver providers charge two types of fees: investment fees and membership fees.

Investment fees are charged as a percentage of your account balance each year. These typically range from 0.4% to 1.5% or higher, depending on your fund. A growth fund might charge 1.2% annually, while a balanced fund might charge 0.9%. These fees come directly out of your balance.

Membership fees (also called administration fees or account-keeping fees) are fixed annual charges, typically $20-$50 per year regardless of your balance size. These fees are charged to cover the cost of administering your account, processing contributions, and managing your membership.

Both fees reduce the net return you receive. For example, if your fund earns 6% in a year but you pay 1.2% in investment fees and $35 in membership fees, your net return is significantly less than 6%.

The compound effect of fees over decades

The real damage from fees happens through compounding. Small annual deductions seem insignificant in year one, but they prevent growth from compounding in subsequent years. This effect accelerates as your balance grows.

Consider a simplified example: a $50,000 starting balance growing at an average 6% annual return over 40 years. The only variable is the annual fee percentage.

Fee levelAnnual fee %Balance at 65Total fees paidLost growth
Low-cost fund0.5%$543,000$28,000
Moderate-fee fund1.0%$467,000$59,000$76,000
High-fee fund1.5%$402,000$92,000$141,000

The difference between the low-cost fund and the high-fee fund is $141,000. That's money you earned through your own savings and investment returns, but lost to fees. The difference between low-cost and moderate-fee funds is still $76,000—enough to fund years of retirement living.

Now consider someone starting with just $5,000 (perhaps they're joining KiwiSaver later in their working life). The same fee comparison applies:

Fee levelAnnual fee %Balance at 65Total fees paidLost growth
Low-cost fund0.5%$54,300$2,800
Moderate-fee fund1.0%$46,700$5,900$7,600
High-fee fund1.5%$40,200$9,200$14,100

Even with a small starting balance, the cost of high fees is substantial. The high-fee fund costs $14,100 more than the low-cost fund over 40 years. For someone on a modest income, that could represent months of retirement spending.

Using the RatePal fee calculator

Rather than using generic assumptions, you can model your own situation using the RatePal KiwiSaver fee calculator. Input your starting balance, expected annual contributions, investment return assumptions, and fees, and the calculator shows exactly how much you'll have at retirement and how much you'll lose to fees.

Visit the KiwiSaver fee calculator to run your own scenarios. You can compare your current fund against other options and see the real-dollar impact of switching. Many people discover they could gain $30,000-$100,000+ by switching to a lower-fee fund—and there's no downside beyond a day or two of administration time.

Quick win

If you're in a high-fee fund, run the calculator right now. Most people find that switching saves them thousands of dollars with zero additional effort—just a fund switch form. That's one of the easiest financial optimisations you can make.

High-fee versus low-fee funds: Detailed comparison

KiwiSaver funds range dramatically in fees. Here's a realistic comparison of how different providers and fund types charge:

Fund typeAnnual fee %Membership feeTotal annual cost ($50K)Typical provider
Low-cost growth0.4-0.6%$0-$20$220-$240Index or ETF-based
Moderate-fee growth0.9-1.1%$25-$35$475-$525Standard managed funds
High-fee growth1.3-1.8%$40-$50$700-$950Premium managed funds

The difference between a low-cost fund and a high-fee fund is roughly $700 per year on a $50,000 balance. Over 40 years, that $700 annual difference compounds into the $141,000 gap we saw earlier. On larger balances, the difference in dollars is even more dramatic.

Finding fee information for your current fund

Your KiwiSaver provider must disclose fees clearly. You can find fee information in several places:

  • Your annual statement: Your KiwiSaver provider sends an annual statement showing fees charged in that year.
  • Product disclosure statement (PDS): The PDS contains comprehensive fee information and is available from your provider or their website.
  • Fees register: The Financial Markets Authority (FMA) maintains a KiwiSaver fees register where you can search all providers and funds.
  • Provider website: Most providers publish detailed fee schedules on their websites, often with fee calculators built in.

Don't assume your fees are reasonable just because you've never questioned them. Many people pay significantly more than necessary because they never bothered to check what competing providers charge.

Switching to a lower-fee fund

Switching funds is straightforward and shouldn't cost you anything. You don't pay exit fees or entry fees when switching between KiwiSaver funds (this is protected by law). Here's the process:

Step 1: Research alternative funds

Identify funds with lower fees that match your investment goals. Use the RatePal fund finder to compare fees, performance history, and risk profiles of all available options.

Step 2: Complete the switch form

Your current provider has a fund switch form. Complete it and submit. The form typically takes 5 minutes to fill out.

Step 3: Wait for confirmation

The provider will process your request, typically within a few working days. You'll receive confirmation once the switch is complete.

Step 4: Confirm the switch in your account

Log into your KiwiSaver account and verify that your balance now shows in the new fund. Your next statement will confirm the switch.

That's it. You don't lose contributions or growth, and you don't pay any fees for switching. The only minor downside is 1-2 days when your money may not be invested (the cash drag while the switch processes), but this is negligible compared to years of fee savings.

Does a higher fee mean better returns

This is a critical question and the answer is clear: no. Higher fees do not correlate with better returns. In fact, the research shows the opposite. Actively managed funds (which charge higher fees) consistently underperform low-cost index funds (which charge lower fees) over long periods.

The logic is simple: active managers charge higher fees because they're paying skilled fund managers to pick stocks and time the market. But decades of research shows that most active managers fail to outperform their benchmark by enough to justify their fees. After you subtract fees and taxes, you're better off in a low-cost index fund that simply tracks the market.

A fund manager might beat the index 2-3 years in a row, but this is generally luck, not skill. Over 20-40 years, the low-cost index fund wins almost every time. You're paying extra money for returns you statistically won't receive.

Evidence-based investing

If you want a high-conviction reason to switch to a low-cost fund, consider the academic evidence. Nobel Prize-winning economist Eugene Fama's research conclusively showed that active fund managers don't consistently beat the market after fees. The lowest-cost option is almost always your best option for retirement savings.

Real-world fee comparison: Two different savers

Let's look at two realistic scenarios to illustrate how fees affect retirement outcomes.

Sarah: High earner in a high-fee fund

Sarah earns $120,000 per year and contributes 4% to KiwiSaver ($4,800 per year). She's been in a moderate-to-high-fee managed growth fund charging 1.3% annually, with a $40 annual membership fee. Over her 30-year working life (age 35-65) with average returns of 6%, her KiwiSaver balance at retirement is approximately $483,000.

If Sarah switches to a low-cost index fund charging 0.5% annually, her balance at retirement would be approximately $537,000—a difference of $54,000. That's not a typo. Switching funds would have given Sarah an extra $54,000 for her retirement, with absolutely no additional work or risk.

James: Average earner joining later

James starts contributing to KiwiSaver at age 45 with a balance of $30,000. He contributes 3% of his $75,000 salary ($2,250 per year) for 20 years until retirement. In a high-fee fund (1.5% annually), his balance at 65 is approximately $165,000.

In a low-cost fund (0.5% annually), his balance would be approximately $189,000—a difference of $24,000. For James, even starting later and with a smaller balance, fee choice still determines a difference of nearly $25,000.

Frequently asked questions

Why do KiwiSaver fees seem so small if they have such a big impact

Because the impact compounds over decades. A 1% difference in fees seems insignificant in year one—just $500 on a $50,000 balance—but over 40 years it compounds into tens of thousands of dollars in lost growth. This is why long-term savings accounts like KiwiSaver are so sensitive to fees.

Can I switch KiwiSaver funds without paying a fee

Yes. By law, KiwiSaver providers cannot charge you to switch between funds. You can switch as many times as you want, with no exit fees or entry fees. Your next statement will show the change.

Do low-cost funds perform worse than high-fee funds

No. In fact, low-cost funds typically outperform high-fee funds because they charge less. After fees, you're almost always better off in a low-cost index fund than in an expensive actively managed fund.

Should I switch funds if my balance is small

Yes. Even small balances benefit from lower fees over time. If you're contributing to KiwiSaver, you'll have decades of compounding ahead. Starting with a low-fee fund now means maximum growth over your 20-40 year investment horizon.

Where can I find detailed fee information for all KiwiSaver funds

The Financial Markets Authority (FMA) maintains a public KiwiSaver fees register. You can search all providers and funds to compare fees, returns, and other information in one place.
