As an avid user itās great to see this product finally launch, though I probably wonāt use it personally. Just FYI though Iām sure youāre aware of it but not everyone might:
The big beasts are taking note. I received updated overdraft terms, which come into effect in Oct I think, from my bank (HBOS), saying theyāll charge 1p per Ā£7 overdraft, and charge and notify me daily. So theyāll be cheaper than you up to Ā£350 in the red, at which point the Monzo flat rate will be better. But the USP about showing interest daily might not stand for much longer. The rest of the Lloyds banking group, and I imagine competitors will probably follow suit.
Interesting to see the details around how overdrafts work. One part I wasnāt clear on, however:
There are a few cases where your account might still go overdrawn without you expecting it ā most notably with delayed transactions from organisations like TfL or bills from hotels that come in late that we canāt reject (because theyāre presentments ā more detail here). Most of the time, these payments should fall within your Ā£20 buffer, but if they donāt, weāll notify you through the app and give you at least until midnight of that day to clear it. If you donāt clear it, weāll just treat the it like the normal overdraft and youāll be charged 50p/day. This will also be reported to credit reference agencies.
Itās not clear to me what happens to people who donāt have an overdraft on their Monzo account. Would they also be charged and reported to the credit reference agencies, or is there some other consequence (e.g. card being frozen until debt paid off)? It seems like there is a risk of accidentally having an overdraft added to the account (and reported), especially if travelling with sporadic access to data for notifications and the chance to fix any issues.
In the future, itāll be as easy as tapping the āOverdraftā button on the Card screen, but for now it might take a bit longer so please be patient.
Another reason why I think the Card tab should be renamed. 
This isnāt card specific, itās about the account. In theory, you could never use the card and still want/use and overdraft.
Thanks for the post, great to see long-discussed features coming to fruition!
Great news.
Just to confirm, if a payment goes out in the morning, a user has until midnight to transfer money into the account to avoid going overdrawn? Thatās the main thing I want from an overdraft: immediate notification and time to put it right 
I think the UI looks great, makes it incredibly clear to users that they are in their overdraft and what they will pay for using it. I like the idea of a constant notification as it constantly reminds users of the charges they face for using an overdraft unlike traditional banks who do their best to hide it.
Iām not entirely sure about the pricing, perhaps banded daily prices (depending on the level of the debt at any given point) could be an option. It seems odd that someone who owes Ā£100 should pay the same as someone who owes Ā£1,000.
I agree on pricing. Iām not a fan of āeveryone pays the same no matter whatā which has been a reason Iāve left banks previously. I prefer the approach Starling 
uses, the daily charge changes based on the amount you are overdrawn!
I may be wrong (and please someone correct me if I am 
), but as far as I can tell, any unplanned overdraft usage would be charged at the same rate as planned overdraft usage, i.e 50p per day for any usage above the Ā£20 buffer. 
I donāt think Monzo would freeze cards as a form of penalisation, since even legacy banks donāt do that 
That said, given that banks have an obligation to accurately report the financial status of your account to credit reference agencies, Iād think that any negative balances (be them planned or unplanned) would be reported to the credit reference agencies. In theory, if you went into an unplanned overdraft and sorted things out quickly enough, youād probably find that this isnāt even presented to the credit reference agencies, and the balance of your account would show as it normally would (in credit or zero) on your credit report; balances like this tend to be reported monthly in my experience.
I totally agree on renaming the Card tab, though 
I think given the added complexities introduced with a current account, something more along the lines of āAccountā or even āProfileā would probably be more suitable.
@alexs has pointed out to me that it looks like itās already planned to rename the tab āAccountsā (use 
to see the screenshots):
I donāt regularly use my overdraft but I think this does penalise people who donāt use it often/not by much. The idea of a flat rate does make it simple to understand / manage though.
Perhaps as a compromise either have tiered rates which could get complicated, reduce the flat rate or increase the buffer. First Direct give you the first Ā£250 interest free on their overdraft.
Confirming it will be 
This maybe a dumb question, but does having an overdraft affect your credit score? For instance i have an overdraft with Halifax and think iāve been in it once, however iāve always been of the impression itās better to have it and not need it rather than need it and not have it?
Iām on Android so it doesnāt apply to my yet, but when it does come to Android i would like to have it activated.
Yes it would affect your credit score. I think it can be positive or negative depending on if you are maxing it out or not.
Having a lot of unused credit could mean that you might get turned down for further credit.
I just received my email invite to test the overdrafts 3 minutes ago, check your inboxes 
This happened to me once early this year, I got an Asda delivery and the charge was shown on Monzo 24 hours before delivery which set my balance to -Ā£6 or something like that (I usually only top up the amount I need when I use the prepaid card). I was surprised I could actually go into a negative balance since there were no overdrafts but Iām guessing they donāt actually take the payment from me since they will do refunds and all that. I simply topped up my card. Iām assuming you wouldnāt be able to use it more if thereās insufficient cash in. Not sure if this was actually meant to happen or if it was a bug, since usually when thereās insufficient cash in it usually gets bounced.
The blog mentions any payments that will take you over the Ā£20 or over your agreed limit will be rejected. What payments specifically is this referring to? Debit card,faster payments and bacs make sense but direct debits? I would prefer time to credit the account before these are rejected.
While monzo may not charge to reject a DD the receiving company may apply a late fee. Can the cut off for these be midday for example with a notification that morning advising payments are pending rejection if funds are not applied to the account.
Not to play devils advocate, but this seems similar to Lloyds Banking Groups new overdraft charges, which is fine, but it became known that their new overdraft charges were equivalent to up to 52% APR. Being an open bank, what is the equivalent up to APR of this 50p flat fee? I could try and calculate it but Lloyds did release this cookie of an APR when asked.
I canāt wait to try this out, however, I canāt see myself using it much due to the cost, maybe because I like to shop around and aget a pretty good rate, I bank with Metro Bank who charge 15% AER. If i was to borrow Ā£250 over 30 days they would charge me Ā£2.89 in fees, the same with Monzo would cost me Ā£15!
If I was to borrow the same amount over the same time with First Direct, it would cost me nothing!
Just my honnest opinion.
Lloyds are able to give an equivalent percentage rate as the amount you pay goes up as you borrow more. Monzo will charge you the same no matter how much youāre in debt. So if youāre Ā£20.01 overdrawn for a whole year youāll pay Ā£182.50. If youāre Ā£5000.00 overdrawn for the same year, youāll still pay Ā£182.50. The equivalent percentage rate would make your eyes water in the first example, but look great value in the second.
Edit: Approx 912.5% in the first example.
Approx 3.6% in the second example.
I think. Havenāt taken into account compounded interest.
Thats my thought. In past years, consumer rights organisations have criticised payday loan firms for their eye-watering equivalent APRās because of fixed fees. Lloyds must have taken this into account and thats why they scaled their approach but it still has a high APR compared to regular credit. I just donāt want Monzo with the headline āstartup bank in 100ās% APR on Ā£21 overdraft debtā. I truly think a lower fee or higher free overdraft level is needed.
As much as I would like to use this and unify all my accounts, itās just not worth the cost when I can use my Santander Student account for free overdrafts. Even a small Ā£500 free overdraft from Monzo would go a long way.
