How do you know if you are saving enough to have decent financial capacity for a reasonable retirement?
It is not an easy question to answer, and waking up to a shortfall when you are in your mid 50s may well be too late.
So we need life-stage markers to ensure we aren't caught short.
Retiring in penury is an outcome best avoided. Actively.
As you would expect, there are many ways to look at this.
First is to know that in retirement you will likely need about 80% of your pre-retirement income if you wish to maintain a similar but more modest living standard.
So, your expected annual salary at aged 65, less NZ Super of about $17,000 each if you are married (details are here), is the income off of your investments that you will need.
If you work this out, you will quickly see the current capital value of a regular income.
Here's an example, assuming you are male and earning the median income for a 64 year old. That, according to Stats NZ (LEEDS) is about $62,630 per year. If you are female and earning the median income for a 64 year old, that is $42,370 per year, and that highlights the extremity of the disadvantage and inequity for women.
So the numbers pan out like this:
| 2018 dollars, pre-tax | Single Male | Single Female | Couple male working |
Couple both working |
| $ | $ | $ | $ | |
| Income pre retirement | 62,630 | 42,370 | 62,630 | 105,000 |
| Target retirement income (80%) | 50,100 | 33,900 | 50,100 | 84,000 |
| - from NZ Super | 23,400 | 23,400 | 35,440 | 35,440 |
| - needed from investments | 26,700 | 10,500 | 14,660 | 48,560 |
| That will require either an investment of a ... | ||||
| Term deposit, returning 3% gross | 890,000 | 350,000 | 488,700 | 1,618,700 |
| or ... | ||||
| KiwiSaver returning 5% gross | 534,000 | 210,000 | 293,200 | 971,200 |
Two points to make up front: If you own a house, you can't 'eat' it. It's value will only be realised if you sell it. Then you have to rent.
And secondly, for the above table to be valid you will need to have faith NZ Super will still be available as it is now, when you retire.
The lower your income, the less likely you will have the ability to save the investment you will need. And the above data is eye-catching because in a low-interest-rate world the invested fund level you will need is very high.
If interest rates rise, fund returns will also likely rise. But the sting may well be that these benchmarks are rising because inflation is rising. And inflation will reduce the purchasing power of whatever you earn. How you can live today with a $50,000 pa income will be greatly different and tough if meaningful inflation returns, - (5% inflation will hurt retirees a lot).
So you need to start soon.
The above table shows how many times your salary you will need to have saved as a minimum. Here it is again focused on how many years of income you need to have salted away.
| 2018 dollars, pre-tax | Single Male | Single Female | Couple, male working |

Depending on your circumstances, you will need between five and fifteen times your salary saved, and invested, to maintain a similar lifestyle in retirement.
It is a daunting prospect.
But you won't get there without a plan, personal financial discipline, and getting started.
If you save 10% of a lifetime income and invest that in growth assets, you may not make it. You will need to save more like 15% per year. Here is the maths again, based in part on Stats NZ LEEDs data and assuming you will retire in 2018. That won't be your scenario, but it might help you think about what a plan personalised for you might look like.
| pre tax | Avg Annual Income |
15% pa saved in 5 years |
5% earned after tax on savings |
Cumulated savings |
| $ | $ | $ | $ | |
| 20-24 | 11,300 | 8,480 | 420 | 8,900 |
| 25-29 | 29,500 | 22,130 | 1,550 | 32,580 |
| 30-34 | 32,500 | 24,380 | 2,850 | 59,810 |
| 35-39 | 35,500 | 26,630 | 4,320 | 90,760 |
| 40-44 | 37,300 | 27,980 | 5,940 | 124,680 |
| 45-49 | 43,500 | 32,630 | 7,870 | 165,180 |
| 50-54 | 49,700 | 37,280 | 10,120 | 212,580 |
| 55-59 | 56,500 | 42,380 | 12,750 | 267,710 |
| 60-64 | 61,100* | 45,830 | 15,680 | 329,220 |
| ----------- | ----------- | |||
| Totals | 267,720 | 61,500 |
* The $62,360 in the first table is the pre-retirement income in the final year of work, whereas the $61,100 in the table above is the average annual income over the five years from age 60 to 64.
Leverage can work for you. If you borrow to buy a house that will be much bigger than you will need in retirement (when you will downsize), then the principal repayment portion of your mortgage will count to your savings rate.
But the main take-away here is the size of the challenge. You need to save about 15% of your gross income per year if you are on a median income, and that will result in total savings of $329,220 at retirement, which when supplemented by NZ Super, will give you an annual income in retirement of a bit over $50,000 per year.
Observant readers will have noticed that this plan will not work if you save using term deposits. You need a growth vehicle like those available in KiwiSaver to reach this target. And that only works out on a long-term basis.
Of course, you can also decumulate. That is, you can use some of your previously saved capital to spend. That is a simple thing to do and with low investment returns it might seem like the immediate cost is low. But consuming your capital is risky at later life stages. You don't know your own life expectancy. And you don't know what age may throw up in terms of medical costs and living assistance.
Finally, you need to protect yourself from changing public policy positions. Younger people with debt (like student loans, for housing, etc.) will be pressing for higher inflation to devalue their debt obligations. Trendy 'social consciences' also like higher public spending including deficit spending, all virtual certainties to reignite inflation - and make NZ Super as we currently know it unsustainable quicker. And accounting for inflation is the toughest challenge when planning for retirement.
(You need to focus on what you need to do. Try to avoid thinking about the fact that the public purse will be available for those who either can't, or can't be bothered.)
