How to plan a monthly budget on iPhone

By Raj and the Sortd team · Last updated 11 October 2026

The simplest monthly budget is one number: how much you want to spend this month. To stick to it you need two more things: a running total of what you've spent so far, and a list of the bills that haven't charged yet. You can keep all three on your iPhone in a spreadsheet or in a budget app.

1. Pick one number for the month

Start with what comes in each month and take away what you want to save. If you're not sure where to start, look at what you spent last month and set the budget a little below it. You can change the number later.

2. Take out the bills that are coming

Rent, your phone plan, insurance and subscriptions leave your account whether you think about them or not. Take the ones that haven't charged yet out of the number first. What's left is what you can really spend, and dividing it by the days left in the month tells you what you can spend each day.

3. Keep the total up to date

This is where most budgets stop working. A budget only helps if your spending is written down as it happens. If you have to type in every coffee, you'll stop after a week or two.

Three ways to do it on iPhone

A spreadsheet in Numbers or Google Sheets

Free, and you can lay it out however you like. You type in every purchase yourself, and you work out the bills and the daily amount with your own formulas.

A budgeting app that links to your bank

Apps such as YNAB, Monarch and Copilot Money bring in your transactions through a bank connection, using services like Plaid. They do a lot, but you have to connect your bank, they charge a subscription, and bank connections aren't available in every country or for every bank.

Sortd

Sortd is a free iPhone spending tracker with a monthly budget built in:

There is no bank login, your purchases stay on your iPhone, and every feature is free.

What Sortd doesn't do

Sortd is not an envelope or zero-based budget, where you give every dollar a job before you spend it. It doesn't connect to your bank or move money, and it is only on iPhone. If you want those things, a bank-linked budgeting app is the better fit.

More guides: finding your subscriptions and tracking Apple Pay spending automatically.

Questions

Is there a free budget app for iPhone that doesn't need my bank?

Yes. Sortd is free, has a monthly budget with optional category limits, and never asks for your bank login. Purchases come from Apple Pay, receipt photos, statements you import, or what you add yourself.

Can I set a budget for each category?

Yes. In Sortd you set one number for the month and can add limits for any category, like eating out or groceries.

Does it count bills that haven't charged yet?

Yes. Sortd takes the bills and subscriptions still to come this month out of your budget before it shows what you can spend each day.

Does it work in my country?

Yes. Sortd works with any bank and any card in Apple Pay, in any country, and converts 30+ currencies to your home currency.
