Setup Your Budget

Enter your starting balance, projection date, and all income and expenses to build an accurate forecast.

Income & Expenses

Monthly Income Sources

Add paychecks, side hustles, or stipends. Include the pay day for accurate projections.

Monthly Bills & Subscriptions

Put in due dates for rent, utilities, loans, or recurring services.

We automatically shift a due date to the month's last day if it doesn't exist (like the 31st in shorter months).

Yearly Bills & Renewals

Great for domains, insurance, or any annual bill. Pick the month and exact day so it lands in your projection automatically every year.

We’ll clamp the day to the end of the month when needed (e.g., a 31st charge in February).

Weekly Expenses (Averages)

Capture flexible spending like groceries, transport, or fun money and pick the weekday it leaves your account.

Each weekly amount deducts on the day you select (default is Saturday to mirror weekend shops).

Daily Spend (average)

A flat amount taken out every calendar day—good for coffee runs, transport taps, or pocket money you spend most days.

Applies across your projection window and counts toward expenses.

One-Off Payments

Add future one-time expenses like buying a phone, vacation, or any planned purchase with an exact date.

Save or move your data (CSV)

Export a CSV backup of your setup or import one to restore your budget fast—perfect when you want to edit on another device.
