I'm trying to make a point - obviously - so bear with me.
- a) it reduces the (eventual) amount of income you will need from your savings/investments
- b) it allows you to save even more
To keep the numbers simple, let's assume a rate of return (or interest rate) of 5% per year (you could earn that from the pick of the 5% dividend yield shares). That means that to generate £1 in 'passive' income you would need savings/investments of £20.
So, if you needed your savings to generate an income of £15,000 a year (say, to supplement your pension or other income), you would need to have saved £15k * 20 = £300,000 - a tidy sum. To appreciate how substantial that is, consider that over, say, 20 years you would have to save around £15,000 a year (a bit less, actually, as you would be earning interest on your savings), which is a lot of money to try to put aside.
However, let's say you are able to permanently save £10 a day in living costs. Over the year that would amount to 356 * £10 = around £3,500 (rounding down to keep the numbers easy). How much capital would you need to have to generate that income? Using the 5% rate of return above, the capital sum required would be £3.5k * 20 = £70,000.
That's a pretty big chunk of the £300,000 we calculated earlier (nearly a quarter), generated through a relatively small daily saving. That would mean that you would only need a capital sum of £230,000, requiring over 20 years £11,500 of savings - a 25% reduction (on the assumptions we've used).
But there's more. If you save that £10 a day you will have saved £3500 over the year, reducing the amount that you need to save elsewhere from £11,500 to £8,000 a year (over 20 years - remember). This is total reduction in the annual savings required from other sources from £15,000 to £8,000 or nearly half the required savings.
All from saving only £10 a day.
So, if I've convinced you - how could you save £10 a day? As a starter, here's 50 things (almost) not to spend your money on.
