For many people running a self-managed super fund in retirement, the headline balance can still look healthy while the money quietly buys less each year. That gap between the dollar figure and its real purchasing power is where Inflation does its damage.

It matters because SMSF retirees typically draw a regular income from their fund, and elevated cost-of-living pressures can erode the real value of both the Capital and the drawings at the same time. Understanding the mechanics of that erosion helps trustees see why a fund that appears stable on paper can still face pressure over time.

How inflation quietly reduces real returns

The starting point is the difference between a nominal return and a real return. If a fund earns a positive return over a year, that is the nominal figure most people notice. The real return is what remains after accounting for rising prices.

When inflation is elevated, part of any Investment gain may simply offset the higher cost of goods and services rather than increasing a retiree’s actual purchasing power.

For a fund still in accumulation phase, periods of weaker real returns may be managed over a longer timeframe. For retirees drawing an income, the impact can be more immediate. Money leaves the fund each year to meet living costs, leaving less capital available to recover after periods of weaker performance.

The combination of regular withdrawals and reduced purchasing power can create pressure that is not always visible when focusing only on the nominal account balance.

Fixed drawings against a rising cost base

Another challenge comes from how retirees structure their income. Some members establish a fixed annual Withdrawal amount based on expected spending needs.

When prices rise, that fixed amount covers fewer goods and services. Retirees may then need to increase withdrawals to maintain the same lifestyle, but higher withdrawals can accelerate the reduction of retirement savings.

Drawing more money from a fund to offset inflation means a larger portion of capital is being used each year. If investment returns do not keep pace with rising costs, the fund may decline faster than originally expected.

This is why the relationship between spending needs, inflation and investment returns requires regular review rather than being treated as a one-time retirement decision.

The minimum drawdown adds another layer

Superannuation rules require account-based pensions to pay a minimum amount each year, calculated as a percentage of the pension Account Balance on 1 July.

The temporary COVID-era reduction in minimum drawdown rates ended, with standard rates applying again from 1 July 2023. For 2026-27, the minimum drawdown rate is 4% for members under age 65, increasing with age to 5% for ages 65-74, 6% for ages 75-79, 7% for ages 80-84, 9% for ages 85-89, 11% for ages 90-94 and 14% from age 95.

These percentages are minimum requirements rather than recommended spending levels, but they interact with inflation in an important way. As retirees age, required withdrawals increase, meaning a greater percentage of the account balance must be paid out each year.

For retirees facing higher living costs, the combination of mandatory withdrawals and reduced purchasing power may require closer monitoring of how their fund is structured.

Sequencing risk in the drawdown phase

Sequencing risk refers to the impact of the order in which investment returns occur, rather than just the average return achieved over time.

For retirees drawing income, poor investment performance early in retirement can have a greater impact because Assets may need to be sold during market weakness to fund pension payments.

Inflation can increase this challenge. If markets decline while living costs are rising, retirees may need to sell investments at lower values while also increasing withdrawals to maintain spending levels.

Consider a hypothetical retiree who experiences weaker market returns during the early years of retirement while increasing pension withdrawals due to rising costs. In this scenario, the fund balance may decline faster compared with experiencing the same market conditions later in retirement. This example is hypothetical and only demonstrates the mechanics involved.

What trustees may want to understand

Inflation does not create a single response for all SMSF trustees. Each fund has different investment settings, member circumstances, spending needs and retirement objectives.

However, inflation highlights the importance of understanding how a retirement strategy performs during periods of rising costs. Trustees may consider how expected investment returns compare with inflation, how much Liquidity the fund maintains and how the portfolio may respond during periods of market volatility.

Trustees are responsible for managing their fund’s investment strategy and reviewing it regularly, taking into account factors such as pension payment requirements and member circumstances.

Questions trustees may consider include how spending patterns are changing, whether portfolio assets align with income needs and how future minimum drawdown requirements may affect retirement balances.

Because these decisions involve personal circumstances, taxation and Retirement Planning considerations, appropriate professional advice may be relevant.

What to watch next

Trustees should continue monitoring changes in household costs, investment returns and pension payment requirements. The annual 1 July balance used to calculate minimum pension payments remains an important review point.

Tracking actual spending against pension income can also help trustees understand whether their retirement strategy continues to match their lifestyle needs and financial position.

Key Insights

Inflation can affect SMSF retirees through multiple channels. It reduces real investment returns, weakens the purchasing power of fixed withdrawals, interacts with minimum pension requirements and can increase the impact of sequencing risk.

A fund balance may appear stable in dollar terms while its ability to support future spending gradually changes. Understanding these factors can help trustees assess whether their retirement strategy continues to reflect changing economic conditions.
