§ 01 · The method

Give every dollar a job.

Zero-based budgeting means income minus envelopes equals zero. Not roughly. Exactly. When the top counter hits $0.00, every dollar in your account is already spoken for.

Income   $3,000.00
Assigned   $0.00

Try it. Tap any envelope. Fill the whole row. Watch the counter drop to zero.

§ 02 · Goals

Five ways to name a number.

Every envelope can carry an intent. Pick the shape that fits — a deadline, a cadence, a cap. Or none; the envelope works fine without one.

§ 03 · Rolling balances

Leftover doesn't evaporate.

If you underspend, the balance rolls to next month. If you overspend, it goes negative and nags you politely until you cover it.
