Migrating from envelope budgeting

Envelope budgeting works by pre-allocating fixed dollar amounts to named categories every pay period. You decide once a month: $1,200 to rent, $500 to groceries, $200 to gas. As you spend, envelopes drain. When one is empty, you stop. The system enforces discipline through scarcity.

It's a great system — for a paycheck. The fixed dollar amounts assume the income is predictable. When you make $14k one month and $2k the next, every envelope plan you build either over-allocates (and breaks immediately) or under-allocates (and feels like a punishment). You spend more time re-planning than spending.

Reserves replace the planning loop. Instead of deciding dollar amounts every month, you decide priority and floors once, and ReservWise routes income across them automatically as it arrives. Each tier has a target balance, not a target inflow. Lean months draw down. Fat months refill and overflow into wealth-building. You stop re-planning.

How envelope concepts map to reserves

• Envelope → Reserve. A named bucket holding dollars for a purpose.
• "Filling" an envelope → Allocation. Reserves fill automatically by priority order, not by manual decision.
• "Stealing from another envelope" → Manual transfer. Same action, with a clean audit trail. See Drawing from a reserve safely.
• "Age of money" → Runway. Reserves track how many months you can run without new income, broken down per tier.
• Scheduled categories (rent, insurance) → Survival reserve floor. One tier holds enough for fixed obligations.
• Goal categories (vacation, equipment) → Sub-reserves under Growth or Lifestyle. See Renaming or restructuring reserves.
• Tax envelope → Tax reserve with rolling auto-skim. ReservWise calculates the right amount automatically — no fixed monthly figure.
• "Roll with the punches" overflow → Surplus rules. Automatic. See Setting Surplus Allocation Rules.

The mental shift

The hardest part of migration is letting go of "I need to plan this month." You don't. Your job becomes:

1. Set six floor amounts that reflect your real life. Not aspirations — real averages.
2. Set a tax rate.
3. Set surplus rules (eventually — wait a month).
4. Stop planning. Watch the system run.
5. Adjust quarterly.

If you're used to opening your budget app every Monday morning and rebalancing, the absence of a planning ritual will feel weird. Sit with it. The system is doing the rebalancing for you, every time income arrives.

Five-step migration

Step 1: Export your envelope data

From YNAB, Goodbudget, or whatever you use, export 90 days of category-level activity to CSV. ReservWise can ingest it for context — see Importing 90 days of CSV.

Step 2: Calculate floors from real spend

Open your last 90 days. For each spend category, take the average monthly (not the highest, not your goal — the actual average). Group them under the six tiers:

• Survival: rent/mortgage, utilities, groceries, insurance, minimum debt payments, transportation
• Business Ops: SaaS, contractors, marketing spend, office, business meals
• Tax: leave at $0 floor — the rolling auto-skim handles it
• Growth: courses, equipment upgrades, business savings, hiring slush
• Lifestyle: dining out, entertainment, travel, hobbies
• Wealth Building: index funds, retirement, long-term savings

Sum each group's averages. That's your starting floor for that tier. Set them in Settings → Reserves.

Step 3: Set your tax rate

If you've been envelope-budgeting taxes manually, look at your last full tax year and divide by gross income. Use that percentage. For most US-based 1099 operators, the starting rate falls between 22% and 30%. See Taxes & Buckets for the rolling-rate setup.

Step 4: Move your existing balances in

Your old envelopes have real money in them. Use Settings → Reserves → Manual deposit on each tier to seed it with the appropriate envelope balance. Don't try to seed every category one-to-one — pool by tier, since reserves are coarser by design.

Step 5: Run for a month before adjusting anything

Resist the urge to tune. The system needs one month of real income to show you what's actually happening. After 30 days, do a 15-minute review and adjust floors. After 90 days, add surplus rules. See Adjusting reserve targets.

What you'll notice as different

• No "income to budget" line. Income gets allocated immediately by priority order. There's no holding tank.
• No monthly plan. Floors are durable. Set them once, adjust quarterly.
• Categories feel coarser. Six tiers instead of fifty envelopes. That's intentional — you can always look at sub-categories in transaction reports, but allocation works at the tier level.
• Tax stops being a chore. Auto-skim handles it on every deposit.
• Lean months don't break the plan. Reserves draw down. You don't redo a budget — you let the system pull from Survival to cover the gap, exactly as designed.

What to do next

• Block off 30 minutes for Steps 1–4 and do them in one sitting. Splitting them across days creates confusion.
• Re-read How the six-tier priority system works before adjusting any floors.
• If you're moving from a long YNAB history, see Reserves vs. savings accounts to decide whether to keep separate bank accounts under the reserve labels.

Envelopes manage scarcity. Reserves manage volatility. If your income is volatile, you've outgrown envelopes — you just haven't named what comes next.
