Create a family and invite members
Enter a family name and monthly budget. Other members can join with an invitation code. Family OS shows the members and owner/member roles so you can see which shared space you have joined.
Review recorded spending together
The family overview brings members’ recorded expenses alongside the shared budget. Check receipt details and amounts: the view reflects saved records, not automatically imported bank transactions.
Review spending pace and remaining budget
Compare spending, budget and the amount remaining. A projection based on the current pace is available from day seven of the month; a daily reference helps you discuss the rest of the month. Estimates change as records are added.
One currency for the shared total
The budget includes receipts in the family currency. Other currencies are not automatically converted or added as equivalent amounts. Interface language can be selected separately from currency.
Check that the data has loaded
The shared overview needs a connection to the server. If an update fails, read the message and retry. Previously loaded data should not be treated as a freshly updated total.
Plan the month around groceries, home and recurring costs
Agree on a shared budget and invite family members with a code. Record household purchases and review contributed expenses alongside the remaining budget. Before a large purchase, compare the family overview with payments still due this month.
A worked monthly family budget
This illustrative household starts with USD 4,000. Each allocation has a separate purpose, and the reserve is excluded from day-to-day spending. The USD amounts are hypothetical, not typical local living costs or a recommended budget ratio.
| Purpose | Monthly plan |
|---|---|
| Housing and utilities | USD 1,400 |
| Groceries and household items | USD 1,200 |
| Transport | USD 300 |
| Children, health and other needs | USD 500 |
| Reserve | USD 600 |
| Total | USD 4,000 |
Divide the remaining allocation by days
An allocation of USD 1,200 for groceries and household items over 30 days gives a daily reference of USD 40. A large shop may exceed that amount on an individual day. Enter the allocated amount in the calculator and do not subtract housing again if it was already set aside.
What to check together each week
Review recorded purchases, unpaid bills and money left for current needs. Agree who records a shared purchase to avoid duplicates. When circumstances change, update the shared amounts before planning more spending.
When household income arrives on different dates
Plan with money already available and list bills due before the next income arrives. A monthly total alone can hide a gap between a bill and a later payday. Recalculate after income arrives or a payment changes; do not treat an expected payment as money already received.
