With interest rates so high, should I overpay my mortgage or top-up my pension?
Though not falling precipitously, the UK’s latest inflation figures are at least nudging in the right direction, with core inflation dropping 0.1% in September, to 6.1%. It’s why the Bank of England were able to continue holding interest rates steady in their latest get-together. No doubt, this is offering some relief for those with lofty interest payments. But moving forward, shifts are likely to be tentative: as is often the case in periods when central banks are fighting to tame high inflation, interest rates have a tendency to rise like a rocket and fall like a feather.
It means for many of us, the twin ravishes of inflation and high interest rates are continuing to put pressure on two of our biggest financial responsibilities: homeowning and retirement, where costs have ballooned. For mortgage holders, costs may increase beyond £500 a month this year; for retirees, withdrawals may need to increase by up to £350 a month.
It raises an interesting consideration: if you’re lucky enough to have some extra dollops of cash and seeking to get your long-term financial health into ship-shape, should you be over-paying your mortgage or boosting your pension? Let’s take a look at some different scenarios.
Which to do
New figures from stockbroker interactive investor (II) hypothetically compared the difference in the long-term wealth of someone with a £200k mortgage on a term of 25 years, who paid £200 extra into their pension each month (so £250 with tax relief) and didn’t prioritise their mortgage at all, versus someone else who paid the extra £200 into their mortgage first, before going on to add the extra into their pension later on. I have assumed the rate of interest stays the same given how inaccurate it would be to forecast.
When the interest rate is set higher than the rate of return from the stock market – 6% vs 5% - the best outcome comes from paying off your mortgage first, as you might expect, with your wealth ending up £17,024 higher.
Likewise, when it’s the other way around, and you receive 6% stock market returns vs paying 5% interest, the best outcome comes from adding to your pension, leaving you £20,049 richer.
What’s revealing is when you make all things equal: setting the level of interest and stock market return at the same rate of 6%. In this scenario, you are left better off paying into your pension first, with your wealth £1,793 higher than if you were to pay off your mortgage first. In short, prioritising pension payments makes you richer.
How pensions can make you richer
The difference in favour of pension payments is explained by tax relief – the government’s tantalising boost to your retirement pot, which for higher rate taxpayers becomes even juicier given the potential for extra relief of up to 25%. If invested in a well-diversified global portfolio of shares, such as Alliance Trust, this can significantly boost your wealth over time due to the extraordinary power of compounded returns.
What’s more, investment trusts such as Alliance Trust have professional stock pickers at the helm seeking potential winners for the portfolio and are able to borrow extra money to invest, which may further add to gains over long periods of time. In addition, there are significantly fewer risks associated with investing in pooled investment products when compared to individual company shares.
Nonetheless, while prioritising pension savings may generously serve our financial well-being, we are human and psychology plays a big part when it comes to our finances.
Paying off your mortgage early liberates you of chunky monthly payments and offers peace of mind in the event your employment situation changes and the cash dries up. Moreover, it may leave you open to potentially better mortgage deals down the line.
All told, one happy solution might be to switch priorities over time: paying off more of your mortgage during periods of higher interest rates, and then boosting your pension when rates fall and the risk & return dynamic of stock markets become relatively more attractive.
