Monzo cash deposits: limits, fees and cheaper routes
Monzo does accept cash despite having no branch network. You can use the Post Office or PayPoint, but the two routes have different per-deposit limits and Monzo charges for the service unless your paid plan includes free deposits.
Monzo currently allows up to £750 of cash deposits per month. At the Post Office, you can deposit up to £750 in one go; at PayPoint, the maximum is £300 in one transaction. Monzo charges £1 per cash deposit. Perks, Max and Max Family customers get three free cash deposits each calendar month, then pay £1 per deposit.
Check the Monzo cash route, fee and current limits
At a PayPoint shop, you hand over your Monzo card and cash and the retailer swipes the card. Monzo says the deposit normally takes around ten minutes to appear. At a Post Office, you insert the card into the terminal and follow the on-screen instructions; Monzo says the money should appear immediately.
The bigger difference is the amount. PayPoint is capped at £300 for one deposit, while the Post Office can take up to the full £750 monthly allowance in a single transaction. If you have £650 to deposit, the Post Office is therefore the cleaner route: one transaction, one receipt and one fee rather than several PayPoint visits.
For Monzo, record the route you actually use rather than writing only “cash deposit”. A branch counter, Post Office counter, PayPoint location or another supported service can have different acceptance and posting rules. Before handing over a material amount, check the bank’s current page or app and save the relevant wording when timing matters. Note the amount, location, date and whether notes and coins are handled differently. That gives you a precise starting point if the balance does not update as expected, and it avoids assuming that a rule from another bank also applies to Monzo.
Before acting on monzo cash deposits: limits, fees and cheaper routes, set one verifiable checkpoint for this step. If £871 is involved, write that figure down rather than relying on memory.
Plan deposits so fees do not dominate small amounts
Monzo charges £1 for each cash deposit. If you pay in £300, £299 reaches the account after the fee. On £300, that is about 0.33% of the cash. On a £20 deposit, the same £1 is 5%. The fixed fee therefore matters much more when you deposit small amounts frequently.
Paid-plan customers on Perks, Max and Max Family get three free cash deposits per calendar month according to Monzo’s current fee information. After the free allowance, the £1 charge applies again. If you already pay for one of those plans, grouping cash into sensible deposits may reduce or eliminate the deposit cost.
Suppose you have £720 from several legitimate household sales. At the Post Office, that amount fits within both the single-deposit and monthly limits, so you can pay it in once. At PayPoint, the £300 transaction cap means at least three deposits would be needed - for example £300, £300 and £120.
On a standard plan, three PayPoint deposits would create £3 of deposit fees, while one Post Office deposit would cost £1. The difference is small in pounds but illustrates why the route matters.
Hypothetical example: suppose you plan to pay in £1061 on Monday and a £763 bill leaves on Tuesday. Do not assume the money becomes spendable the moment the counter accepts it. Ask when the credit should be available, keep the receipt and leave enough headroom for the outgoing payment until you can see the cash in the account. If the route has a transaction or daily cap, split deposits only when Monzo explicitly permits it. Repeated attempts can make a simple cash task harder to reconcile if one part is delayed or rejected.
Reconcile the receipt, fee and account credit
Monzo’s £750 limit is monthly. Once the total cash you have paid in during the month reaches that figure, another cash deposit will not fit until the allowance resets. Bank transfers, salary payments and other electronic credits are a different matter; the cash limit is not a general cap on money entering the account.
If you routinely need to deposit more than £750 of personal cash every month, Monzo may not be the most convenient primary account for that pattern. You can still keep Monzo for digital banking while using a bank or account designed around heavier cash use.
PayPoint deposits should normally appear within about ten minutes; Post Office deposits should appear immediately. Keep the paper receipt until the balance is correct. If a £300 PayPoint deposit shows as £299, remember that the £1 fee may explain the difference; if the credit is missing entirely, that is a different issue and should be reported.
When you contact Monzo, give the amount, time and location. Do not make another deposit just to test the service before the first one is traced.
Reconcile a Monzo cash deposit as a small audit trail: receipt amount, account credit, time posted and any fee should agree. If you regularly bank cash, keep a simple log so that a missing £1114 deposit is distinguishable from yesterday’s takings or another employee’s transaction. Photograph thermal-paper receipts because they can fade, but keep the original until the statement is correct. For a partial credit, report the exact difference rather than saying the balance looks wrong. Specific numbers let the bank trace the counter or terminal record much faster than a general description.
Trace any missing or partial Monzo cash deposit
Monzo built its service around electronic money movement, not branch cash handling. The Post Office and PayPoint facilities are useful precisely because they fill that gap, but the £750 monthly cap and per-deposit fee tell you that cash is an ancillary service rather than an unlimited feature.
For an occasional birthday gift, marketplace sale or small amount of cash wages, the service can be perfectly adequate. For regular four-figure monthly cash receipts, choose an account structure that matches the reality of how you are paid.
- Check the live limit for the exact account and deposit route.
- Count the cash before you leave home and keep notes and coins organised.
- Take the card, PIN or paying-in material the provider requires.
- Keep ordinary evidence for a large or unusual lump sum.
- Keep the deposit receipt until the balance is correct.
- Use only the bank’s official app, website or verified contact details if something goes wrong.
If a Monzo cash deposit remains missing or is credited incorrectly, report the exact amount, route, location and receipt reference and ask for a trace or reconciliation case. Keep the complaint reference and record any direct financial consequence, such as a returned payment caused by the missing credit. Do not replace the evidence with a second deposit unless you have considered the risk of duplicating funds later. The practical goal is to connect one physical handover to one account entry, then document the bank’s explanation if those two records do not match.

Monzo’s cash service is much better than “app-only bank means no cash”, but it is still designed for occasional use. The Post Office is the obvious choice for anything above £300 because it can take the whole £750 monthly allowance in one go. The fixed £1 fee also makes tiny frequent deposits poor value unless your paid plan includes free deposits.
Figures and service rules were checked against the provider’s current UK help pages on 28 September 2026. Limits can change, so confirm the live rule before carrying a large amount of cash.
