Why should a UK budget run from payday, not the 1st?
Because the money arrives on payday, not on the 1st. A UK salary is usually paid once a month, often in the last week of the month or on a fixed date such as the 25th or 28th. If your budget resets on the 1st, the last few days before payday look like a crisis and the first few after it look like a windfall, and neither is true.
A payday month fixes that. It starts the day your salary lands and ends the day before the next one. Every bill you pay in that window is paid from that salary, and the number you are trying to protect is simply what is left until the next payment. If payday moves when it falls on a weekend or bank holiday, move the start of the month with it.
What comes out before I can spend anything?
Three kinds of money leave on their own, and a budget should treat all three as already spent.
- Direct Debits. The company collects them, and the amount can change, so use the latest amount, not last year's. Energy, phone, broadband, insurance and subscriptions usually sit here.
- Standing orders. You set them, for a fixed amount on a fixed day: rent paid to a person, savings transfers, money to a partner.
- Council tax. By default it is collected in ten monthly instalments, usually April to January, so February and March look cheaper than they are. You can ask your council to spread it over twelve months, which makes every month the same.
Add up whatever in those three lists leaves between this payday and the next. That is the bill reserve. Only what is left after it is yours to spend.
How much can I safely spend today?
Take what is left in your current account, subtract the bill reserve and anything you have chosen to set aside, and divide by the days until payday, counting today. If the answer is below zero, the honest number is zero.
| Example, 12 days before payday | Amount |
|---|---|
| Left in the current account | £640 |
| Direct Debits and standing orders still to go | £238 |
| Set aside for a friend's wedding | £100 |
| Left to live on | £302 |
| Spend per day for 12 days | £25.16 |
Work it out again every morning. A big shop on Saturday lowers every day after it a little, rather than leaving the last week empty. The safe-to-spend calculator does the arithmetic in pounds.
Can my iPhone see my UK bank account?
Often, yes. Many UK banks let you add your current account to Apple Wallet, not only your debit card. Once it is there, Wallet shows the account's balance and recent transactions, collected through Open Banking with your bank's own consent screen. If your bank offers it, you will see an option when you add the card, or under the account in Wallet.
That changes what a budgeting app needs. With your permission, an app can read the accounts you have put in Wallet through Apple's own data permission, the same kind of one-tap prompt as for photos or location. You never type your bank password into the app, and you can switch its access off in Settings at any time. Not every bank or account type supports it yet, and a credit card from a bank that does not offer it will not appear.
What if my bank is not in Apple Wallet?
Use your bank's own export. Almost every UK bank and card provider lets you download transactions from online banking as a CSV file, and every one sends a statement as a PDF. Download the last full payday month, and you have every purchase with its date and amount, already in pounds.
For day-to-day taps, the Wallet automation in Shortcuts can record each in-store Apple Pay payment the moment you pay, with no bank connection at all. The Apple Pay tracking guide explains what it catches and what it misses.
How does Tally do this in the UK?
Tally reads the UK bank accounts you have added to Apple Wallet, once you allow it, so your current account comes in without a bank login in Tally. That is free. In-store Apple Pay taps can be logged the moment you pay, also free. Anything else comes in from your bank's CSV or PDF statement.
You set the day you are paid, and Tally gives you one number each morning: what is safe to spend today, with the bills due before payday already set aside. Amounts show in pounds, and purchases made abroad keep their own currency next to the converted amount. Tally Pro, for shared budgets, the AI connection and the deeper reports, costs £7.99 a month or £79.99 a year on the UK App Store, with a 7-day free trial for new subscribers.
