🔁 From Saving to Spending

For your whole working life the task is to build savings. In retirement the task flips: you have to turn that pile of money into a reliable income that lasts as long as you do. This stage is called drawdown, or decumulation, and it brings its own questions. How much can you safely take each year? What if markets fall early on? How do you avoid both running out and being needlessly frugal?

                Key Point: Drawdown is the art of converting savings into income without running out or living too small. NZ Super provides a base, and your savings, including KiwiSaver, top it up. The amount you can safely withdraw depends on your balance, how it is invested, how long retirement lasts, and inflation. A common starting guide is drawing around 4% of the balance a year, but flexibility, a sensible fund mix, and a cash buffer matter just as much as the headline rate.
            

The Two Risks That Define Drawdown

Risk	What It Means
Running out too soon	Spending too fast, or poor early returns, drains savings
Living too frugally	Being so cautious you miss the retirement you saved for

Good drawdown sits between these two. NZ Super, which keeps coming regardless, makes the balance easier because your essentials are partly covered no matter what your savings do.

📐 Drawdown Methods

Common Ways to Draw an Income

Method	How It Works	Trade-off
Fixed percentage	Take a set percentage of the balance each year	Income rises and falls with the balance
Fixed dollar amount	Take the same dollar income each year, often inflation-adjusted	Steady income but can drain savings if returns are poor
Bucket approach	Hold cash for near-term spending and growth assets for later	More to manage, but smooths the ride

The 4% Starting Point

A widely quoted guide is to withdraw about 4% of the starting balance in the first year, then adjust for inflation. On a $500,000 balance that is roughly $20,000 in year one, on top of NZ Super.

The Bucket Idea in Plain Terms

Many retirees split savings into a short-term bucket of cash and steady assets for the next few years of spending, and a long-term bucket of growth assets for later. You spend from cash, and refill it from the growth bucket over time, so you are not forced to sell growth assets in a downturn.

                Why a cash buffer helps: Holding a year or two of spending in cash means a market fall does not force you to sell investments at a low point to fund this year's bills. It buys time for markets to recover.
            

🛡️ Making the Money Last

Sequence Risk

The order of returns matters enormously once you are withdrawing. A run of poor returns early in retirement, while you are taking money out, can do lasting damage, because you sell more units to fund spending and there is less left to recover. The same average return with bad years later hurts far less.

A cash buffer and flexible spending soften this risk

Inflation Over a Long Retirement

Retirement can last 25 to 30 years or more. Prices roughly double over a few decades at modest inflation, so an income that feels fine at 65 can feel tight at 85. Keeping some growth assets helps your income keep pace.

Fund Mix in Retirement

It is tempting to go fully conservative at 65, but a long retirement is still a long timeframe for part of your money. Many retirees keep a portion in growth assets for the later years while holding cash and steadier assets for near-term spending. Match the mix to when you will spend each part.

💡 A Practical Approach and Mistakes

Be Flexible

The single most powerful tool is flexibility. Trimming withdrawals a little in poor years, and spending a bit more after good years, makes savings last far longer than a rigid fixed amount. You do not have to decide your spending for the next 30 years on day one.

Common Mistakes

Mistake 1: Going Fully Conservative at 65

With decades of retirement ahead, holding everything in cash can mean your income fails to keep up with inflation. Some growth usually still belongs in the plan.

Mistake 2: Selling in a Downturn to Fund Spending

Without a cash buffer, a market fall forces you to sell low. A buffer of near-term spending avoids this.

Mistake 3: Ignoring Sequence Risk Early On

The first few years of retirement are the most sensitive. Be a little more cautious with withdrawals then, especially if markets are weak.

Mistake 4: Being Too Frugal

Many retirees underspend out of fear and miss the active early years. A plan you trust lets you enjoy what you saved.

A Simple Drawdown Plan

1. Count NZ Super as your base income

2. Set a starting withdrawal, around 4%, on top

3. Hold a cash buffer for one to two years of spending

4. Keep some growth assets for the later years

5. Review yearly and flex spending with how markets go

Final word: Drawdown turns a lifetime of saving into a lifetime of income. Lean on NZ Super as your base, start with a sensible withdrawal rate, hold a cash buffer, keep some growth for the long years, and stay flexible. That combination guards against both running out and living smaller than you need to. This is general information, not personalised advice; many people get tailored advice for this stage.
