Proactive budgeting, not reactive tracking

Know exactly
what to set aside.
Before you spend it.

Atom Budget works out how much of every paycheck already belongs to bills that haven't arrived yet, and tells you, at any moment, exactly what you should still be holding.

No account needed.

This is the real allocation engine running on a sample budget, right here in your browser. Change the numbers to yours and watch your next paycheck split itself.

Most budgeting apps
look backwards.

They tell you what you spent. Atom Budget tells you what to do, before money leaves your account.

Bill arrives. Account is short.
You knew the bill was coming. But between paychecks you spent what wasn't yours to spend.
Charts don't prevent overspending.
Seeing a pie chart of last month's spending is interesting. It doesn't help you make better decisions today.
Different bills, different dates.
Rent on the 1st. Car insurance on the 15th. Annual subscriptions you forget about until they hit.
You don't know what's "free to spend."
Your balance looks fine. But some of that money is already spoken for by upcoming bills.
The science of it

The number no
tracker can tell you.

A bill due in three weeks is already partly yours to save for. Atom Budget works out how much of it each payday carries, and adds it up across every bill you have.

Rent, due the 1st
$1,540.00
Four paydays between now and then,
so each one carries $385.
Fri 7th
$385
Fri 14th
$770
Fri 21st
$1,155
Fri 28th
$1,540
Do that for every bill at once and you get a single figure: what should still be in your account right now.
It survives mismatched schedules
Weekly, biweekly, monthly, quarterly, yearly. A weekly bill is counted weekly, not squeezed into one payday and forgotten for the rest of the month.
It knows what's already spent
A bill that has come and gone leaves the pool. What's left is only what you're still saving towards, so the number never quietly inflates.
It needs nothing from your bank
Every figure comes from your own plan, not from a connection you have to set up first. Link an account later if you want it checked against reality.

Three steps to a
paycheck plan.

01
Add your income sources
Salary, freelance, side hustle: add every source of money with its payment schedule.
02
Add your expenses
Rent, utilities, subscriptions: add every recurring cost with its frequency and due date.
03
See your paycheck plan
Atom Budget calculates exactly how much to set aside from each paycheck for each expense.

Built for how you
actually get paid.

Most budgeting apps assume you get paid once a month. Atom Budget handles any schedule.

Smart allocation
Your paycheck,
already divided.
Before you touch a dollar, Atom Budget shows you exactly how to split it. Bills coming up before your next paycheck get funded first. Everything else is genuinely yours.

Car payment

Yours to spend
$748
Any frequency
Weekly, biweekly, monthly,
quarterly, yearly.
Every schedule counted properly. A quarterly bill accrues across three months instead of ambushing you, and a short month never quietly skips a payment.
Budget health score
A single number
that tells the truth.
Your health score shows what percentage of income is genuinely yours after every obligation is covered.
Color coding
Your colors,
everywhere.
Assign a color to each income or expense. That color follows it through the ring, the calendar and every breakdown.
Calendar view
See the whole month
at a glance.
Every income and expense plotted on a calendar. See what's coming, when it hits, and how each paycheck flows.
Categories
Where it actually
goes.
Group bills into housing, transport, subscriptions and the rest, and see what each one really costs you in a month, not just what you paid last week.
One-off adjustments
When this month
is different.
An electric bill that's usually $115 was $180 in January. Change that one occurrence without touching the bill, or pause something entirely while it's on hold.
Savings goals
The exact day you
can afford it.
Name the thing, pledge a little from every paycheck, and Atom Budget tells you the date you'll have enough. Bills come first, always; the pledge only takes what's genuinely left.
Web and mobile
The same plan,
in your pocket.
A phone app built for a phone rather than a shrunken website. The same figures, the same maths, wherever you check them.
Bank import · Pro
Your bills, found
for you.
Connect your bank and Atom Budget reads the bills and paychecks that repeat in your statements. You review everything before it lands in your budget, and new recurring activity gets flagged as your bank reports it.
Email worth opening
We only write when
you can act.
No news, no tips, no monthly statements. An email arrives when your balance drops below the plan, a bank connection needs you, or a renewal is coming, around 8 in the morning in your own timezone. Every one has an off switch.
Your data is yours
Take it with you,
any time.
Download your whole budget as a spreadsheet or JSON whenever you like. Cancelling keeps every item you imported, and deleting your account really deletes it.
