An equal-share estimate, rounded to the nearest penny. Adjust your actual shares together.

THE FORMULAMonthly costs = rent + utilities + groceries + other costs. Each share = monthly costs ÷ people.

Start with the costs you share.

Add your monthly rent, utility bills, shared grocery budget and any other household costs. For weekly spending, multiply by 52 and divide by 12 to estimate an average month.

Only include costs that everyone has agreed to share. Personal subscriptions or individual shopping can stay outside this budget.

A useful starting point, not a house rule.

This estimate assumes an equal split and the same spending every month. Annual costs are the monthly total multiplied by 12. Real bills can change, so update the numbers when you know more.

The currency selector labels your amounts without converting them. Use the result for planning, then record actual expenses and agreed shares in Splitr.
