Debt doesn't break VaultRule. In fact, the two-account system makes debt payoff easier because it forces one thing: your bills stay safe while your payoff speeds up only when it's actually affordable.
This page shows the simple setup: what goes in Vault, what stays in Flow, and how to automate extra payments without creating "oops" months.

The one rule to remember
Minimum debt payments are Vault. Extra debt payoff is optional until you decide to lock it in.
If you do this, you'll never "pay debt aggressively" and then miss rent, utilities, or groceries.
The 3-lane setup (simple and clean)
- Lane 1: Vault = all bills + all debt minimums.
- Lane 2: Flow = daily spending (capped).
- Lane 3: Debt Paydown = one extra payment you automate (only when Vault is stable).
Step 1: Put every required payment in Vault
- Rent / mortgage
- Utilities + insurance
- Minimum payments for all debts (credit cards, loans, BNPL, etc.)
- Any annual or irregular bills you must cover (see Annual Bills Checklist)
Calculate your monthly Vault target with minimums included: How to Calculate Your Vault Amount.
Step 2: Stop calling spending "bills"
When debt is present, the most common mistake is turning optional spending into "must pay" expenses. Keep Vault clean, or it becomes impossible to win. If you're unsure what belongs where, use: Bills vs Spending and Vault vs Flow: What Counts as a Bill.
Step 3: Set a Flow limit you can actually hold
With debt, your Flow limit is the guardrail that prevents "I'll just use the card" moments. Keep Flow tight enough to create room — but not so tight you rebound and abandon the system.
Flow guide: How to Set Your Flow Limit.
Step 4: Choose your payoff mode
Pick one based on how stable your cash flow is — and stick to it:
Mode A: "Safe default" (recommended if money is tight)
Vault covers minimums. Extra payments only happen if Flow has room at the end of the week or month. If Flow runs out, extra payments pause automatically. See: What to Do When Flow Runs Out.
Mode B: "Accelerate" (recommended if income is stable)
Add one fixed extra payment into Vault — a "locked-in payoff bill." Example: "Debt Extra Payment — €150" goes into Vault monthly. This turns payoff into a guaranteed system instead of a willpower decision.
Step 5: Pick one priority debt at a time
Don't scatter extra payments across everything. Choose one target and hit it consistently:
- If you want math: target the highest interest rate first.
- If you want motivation: target the smallest balance first.
Either approach works. What matters is that your Vault stays protected while you do it.
Autopilot setup (use this table)
| Payment | Where it belongs | How to run it |
|---|---|---|
| Debt minimum payment | Vault | Schedule or autopay from Vault lane |
| Extra debt paydown | Debt Paydown lane | One automated payment after payday (when Vault is funded) |
| Daily spending | Flow | Capped weekly/monthly allowance |

Don't forget annual bills (they break debt plans)
Most debt plans fail because annual or irregular bills show up and force you back onto credit. Capture them once so Vault can handle them automatically: Annual Bills Checklist.
If money is tight this month
Don't skip bills to "stay aggressive." Do this instead:
- Pause extra paydown first. Minimums still get paid (Vault).
- Freeze non-essential spending temporarily to refill Vault: Flow Freeze Rule.
- If Flow is already empty, reset cleanly: What to Do When Flow Runs Out.
Common mistakes (and the fix)
Mistake 1: Paying extra before Vault is funded
Fix: Fund Vault first. If Vault is short, this month is not an "extra payment month."
Mistake 2: Using credit cards as Flow when Flow runs out
Fix: When Flow hits zero, stop discretionary spending. Using credit cards for daily spending creates more debt. Use: VaultRule Card Strategy: One Card for Flow.
Mistake 3: Missing annual bills and "random" fees
Fix: Capture them once so they never surprise you again: Annual Bills Checklist.
