Interest rate help

Can someone explain to me how the total balance after a year of this example is what it is?
I had been looking at taking this account out but I can’t see how there’s only £162 interest at 5%. It’s calculated daily.

Because you don't put in the full £6,000 at the start. Your average balance across the year would be £3,000

Are you thinking that the correct interest should be 5% of £6000, or thereabouts? It's a common mistake.
As it's a regular saver you don't have the full balance in there for a year - only the first £500 gets the full 12 months interest. The second £500 gets 11 months interest... And the last £500 gets a mere 1 month's interest.
Overall it works out as about half the "headline" rate, depending on exactly when you start saving (as not all months are the same length), and plus a little for compounding.1 -
In the first month you deposit £500, you get your interest on £500 for that month in your case daily - but I'm going to do it monthly so you can understand the principle of what's going on. (You get 1/12th of 5% - £2.08 interest approx)
In the second month you deposit £500, you get your interest on £1002.08 for that month. (1/12th of 5% - £4.17 interest approx)
In the third month you deposit £500, you get your interest on £1506.25 for that month. (1/12th of 5% - £6.27 interest approx)
4 - £2012.52 (£8.39)
5 - £2520.90 (£10.50)
6 - £3031.40 (£12.63)
7 - £3544.03 (£14.77)
8 - 4058.79 (£16.91)
9 - 4575.70 (£19.65)
10 - 5094.76 (£21.23)
11. £5615.99 (23.40)
12. £6129.38 (£25.58)
Total: £6154.95 (This is different to your total illustrated - as I'm calculating monthly - and they are calculating daily - but you can see how it works - it would do the same for each of the days - 1/365th - some months are longer than others - so that would have a minor impact on the total as well as your £500 wouldn't be deposited on exactly the same timescale each time) (I think I've got my maths right - but happy to be corrected if I'm wrong)
You're not getting 5 percent interest on £6000 if that's what you're thinking, as the £6000 isn't all there from day 1.
The 5 percent interest is for a year - so each month they pay interest you get 1/12th of the 5 percent - or as you mention interest is calculated daily - so each day you'll get 1/365th of 5 percent of whatever the balance is that day. Each time you go up £500, the 1/365th will be a little more in £ note terms.

Thanks for the replies, I see where Iv went wrong. I was seeing 5% on every deposit that went in plus the previous deposits.
so is this case scenario the same for all savings accounts?0 -

As always, check the terms and conditions, but anything else is uncommon.1 -

However, Barclays have an account which pays 5% on up to £5,000 which can be deposited on day 1.
In this case, after 1 year the interest earned on £5k will be £5,000 x 5% which is £250.1 -

Approx formula for regular saver interest is 6.5 x monthly deposit x interest rate/100Exact will depend on exact days between deposits but will be within a pound or two of above.2
