Household budgeting for New Zealand.
Weekly and monthly budgets you can edit like a spreadsheet, a 12-month cash flow forecast, and your bills, subscriptions, receipts and loans — in one calm place.
What JamJar does
Built for how New Zealand households actually get paid and billed.
Weekly and monthly budgets
Give each category a weekly, fortnightly or monthly amount. JamJar converts between them, and the whole budget is an editable grid — like a spreadsheet, without the formulas.
12-month cash flow forecast
A year behind and a year ahead in one grid: real spending alongside a forecast you can edit cell by cell, with opening and closing balances.
Bills
See what’s coming before it lands, on a calendar and a list. Not paid yet? Move just that one bill without changing the schedule.
Subscriptions
Every repeating charge in one list, with what it costs a year — and how to cancel it.
Receipts
Take a photo of a receipt and JamJar finds the matching payment.
Loans and mortgage
Balances and a payoff date for every loan, with repayments that follow their schedules in the forecast.
Also: savings goals and scenarios, net worth, a weekly review, one-offs that don’t skew your averages, shared household access, and passkey sign-in. Live bank feeds Coming soon — CSV import works today.
How it works
Bring in your transactions
Upload CSV statements from your bank. They’re cleaned up and categorised automatically. Live, read-only bank feeds are coming soon.
Fill your jars
Give each category a weekly or monthly amount — rent, groceries, fuel, kids’ sport — and the numbers always line up.
Check in each week
See what’s left to spend, what’s running over and which bills are coming, then do a quick weekly review together.
A look inside
Screenshots use made-up demo data — no real households.
