Clarity, without the spreadsheets

BigBudget focuses on one job: telling you how much you can spend—today—and when you might dip negative.

1

Bank-anchored starting point

We start with your live bank balance—not guesswork—so your forecast matches reality.

2

Pending-aware import

Pending transactions won’t double-count. When they post, we swap them seamlessly.

3

Cash runway & worst day

See the lowest point ahead, the buffer you need, and what’s safe to spend right now.

How it works

  1. 1 Connect your bank securely and pick which accounts to track.
  2. 2 Add recurring bills & paychecks (or import from your old budget).
  3. 3 BigBudget shows “Spendable Now” and highlights your worst cash day.

Questions, answered

Do I have to categorize everything?

No. Categories help, but Spendable Now and worst-day forecasting work without perfect categorization.

How do you avoid double-counting pending?

We store pending separately and replace them when they post—so your totals stay accurate.

What’s “Spendable Now”?

Today’s balance minus the cushion required to survive your worst cash dip ahead—plus your safety buffer.
