Six cappuccinos or a year off your home loan?

If you have R150 in your bank account once all your fixed monthly expenses have been paid, would you typically spend or save this extra amount? If you are like many South Africans, you’ll feel that R150 is just too little to make a dent in your home loan or retirement savings so you’ll end up spending it instead.

André Wentzel, Solutions Manager at Sanlam Personal Finance, begs to differ. “R150 can seem like such an inconsequential sum that people would rather use it for a few cappuccinos or to treat themselves to a takeaway dinner. But doing this means missing out on the opportunity to turn a relatively small amount into a larger long-term investment.”

Wentzel says, “It really helps to be able to visualise short-term rewards versus long-term pay-backs to understand the effect of compound interest and how small sacrifices now can make a big difference later.”

To practically demonstrate this, Wentzel decided to do the maths. Here’s what would happen if a person decided to invest the extra R150 in his or her future rather than on instant gratification:

1. Towards your retirement

If you save an additional R150 per month towards retirement, this will accumulate to between R400 000 or R500 000 in 30 years’ time, depending on what you assume the investment return to be. For example, an 8% return will yield R405k and a 9% return will yield R473k, after investment costs. (This also assumes that you increase the R150 per month in line with inflation each year.)

2. Towards your home loan

On a R700 000 home loan, assuming an interest rate of prime (10.25%), the monthly instalment for a 20-year loan will be R6 608 per month. When contributing an extra R150 each month, the loan will be paid off in around 19 years instead of 20 and you’ll save approximately R70 000 in interest over this period.

3. Paying off your credit debt

Paying off a credit debt of R15 000 over three years works out to a repayment of R525 per month (at an interest rate of 18% per annum). An extra R150 per month means you can pay it off nine months earlier, saving approximately R1 100 in interest.

Now, here’s what R150 could get you in the short-term:

  • 16 California rolls
  • 6 cappuccinos
  • 2 basic T-shirts
  • 2 movie tickets
  • 1 gigabyte of data

Wentzel says that practical exercises like this make the longer-term gains more concrete, “The trick to switching people’s thinking from a short-term bias to a longer-term one is to better articulate long-term goals and find ways to make these seem attainable.”

According to Wentzel, people with longer-term mind-sets typically have more retirement savings and are often better at managing credit. Additionally, being clear on their goals means that they’re frequently more active in finding ways to save and avoid expense creep.


Wentzel’s three tips for shifting to a longer-term mindset are:

  1. Take the time to really consider what you want to achieve financially in the next five, 10, and 20 years. Compile a list of long-term goals and order these in terms of priority. Consider the potential trade-offs you’ll need to make for each goal. Then chat to a financial adviser.
  2. Use FinTech to budget better, track your expenditure, and visualise and articulate your longer-term savings and investment goals – and monitor these. If your investments aren’t performing, chat to your financial adviser and make a change, if necessary.
  3. Pick an appropriate savings vehicle for each goal based on how long you plan to save for, the likelihood that you’ll need to draw on those savings before the end of your planned savings term, and your tax circumstances. You also need to consider whether you can afford to consistently save the extra amount or whether you’ll contribute more erratically when funds are available.

More tips to save an extra R150 (or hopefully more) each month:

  • Wait 30 days before buying a non-essential item that’s over a certain amount – e.g. R500 or R1000 – to see if you still want it. If you don’t buy it, consider saving the money you would have spent.
  • Only buy what’s on the shopping list and consider online shopping for easy price comparisons between providers and to avoid the temptation of the mall.
  • Pack your own lunches and save what you would have spent on a meal.
  • Cancel unused club memberships and subscriptions and consider saving what you were spending.
  • Monitor your data usage, ensure you have a suitable data plan in place and reduce your consumption when possible, especially when you have regular access to free WiFi.
