Sorry to burst that bubble of a calculation. The chances of you getting 5% interest for next 30 years is small. Whilst historic averages would say it’s easily achievable going back as far as to 1695, economics and banking has changed since 2000, and interest rates are likely to be lower averages going forwards.
besides, at that 5% you’ll get to a point that you’ll need to be paying tax on that earnt interest.
best to put in an easy access ISA to protect from tax when it reaches that level, but loose on lower interest rates.
plus if inflation continues to outstrip interest then it may be worth £44k but it will buy considerably less than her £10k will buy now in 30 years time.
If she were to be aiming to locking money away for that long, shes better to put into some form investment, or better still save it through salary sacrifice into your pension where it will be boosted by 20% at minimum by government tax relief. But that ain’t what she’s saving for, I assume form this post,
im assuming, like most folks here, this is a bail out, rainy day cushion. That’s fantastic and a great starting point to accumulating wealth. But it’s money that’ll be used before 30 years inevitably and hopefully over time will be start of building more security
remember, op, it is much much easier to make money when you have some already. The more you have the easier it is to grow. Millionaire claiming they’re clever in being able to make money is really arrogant:if you have £1m invested you’ll have to be particularly stupid or really thick not to be making a minimum of £130, currently, each and every night, just overnight, while you’re sleeping and doing precisely nothing clever. When you have an income of £30,000 and 4 mouths to feed, there’s no way you can save £130 each night, no matter how clever you are. In fact you need to be very smart and financially savvy to not get into debt
You have done the first hardest bit to save something from nowt. Build on that now, and make it work hard for you. chase down interest rates, move it to where it makes most and uses tax allowances. try to keep on adding saving where and when you can. Don’t forget to invest a little extra in pensions too, even an extra £20 a month . Most tax efficient way of saving still. Yep, you will likely need to spend it at some point, don’t get disheartened. You’ve done it once, you know how, build it up again. Money is there to be used and spent; wisely.
