Plan every dollar β€” before you spend it.

Arca is envelope budgeting for households. Assign the money that's actually in your accounts to what matters, see overspending coming before it lands, and stay ahead of the bills you know are due.

Only real money

You budget what's in your checking, savings and cash today β€” not projected income.

See trouble early

An envelope turns amber, then red, before a planned bill would overspend it.

Plan the irregular

Recurring bills, savings goals with deadlines, and a forward look at every account.

The whole household

One plan, everyone who shares the money kept in sync.

What you get

A complete picture of your household's money

Built around the envelope method β€” assign the money you have, spend from what you assigned.

βœ‰οΈ

Envelope budgeting

Assign every available dollar to a category. When an envelope's empty, you're done spending there β€” no overdraft surprises.

🏦

Every account in one place

Checking, savings, credit cards, loans and investments. Enter transactions in seconds; Arca keeps a running balance on each.

🎯

Targets that fit real life

Set a weekly, biweekly, monthly or yearly spending target β€” or a savings goal by a date. Arca tells you what to set aside this month and re-paces it as you go.

πŸ“…

Planned transactions & forecast

Enter recurring bills once. Arca shows what's coming, flags the envelopes that won't cover it, and projects each account's balance forward.

πŸ“Š

Reports that matter

Net worth over time, spending by category, month-to-month trends, and a β€œcash cushion” β€” how many days of expenses you have saved.

πŸ‘ͺ

Made for households

Invite the people you share money with. Everyone sees the same plan and the same balances, updated as they happen.

How it works

Up and running in an afternoon

1

Add your accounts

Enter today's balances. No bank login required β€” Arca never asks for banking credentials.

2

Build your plan

Create categories and assign every available dollar until β€œReady to Assign” is zero.

3

Adjust as you go

Record what you spend and move money between envelopes when life changes. That's the whole method.

Good to know

Questions people ask first

Does Arca connect to my bank?

Not yet. Arca is manual by design right now β€” you enter balances and transactions yourself. That keeps your banking logins out of it entirely, and most people find that recording spending as it happens makes them far more aware of where the money goes.

Can I share it with my partner?

Yes. A plan belongs to a household, not a person β€” invite anyone you share money with and they see the same budget and balances.

Is there a mobile app?

Arca works in any mobile browser today and is built for it. A dedicated iOS app is on the way.

Is my data secure?

Your data is encrypted in transit and at rest and hosted on AWS.
