Data Collection
Collect the following for each debt type held:
1. Overdraft (Dispositionskredit / Dispo)
- Credit limit (€)
- Current outstanding balance (€)
- Interest rate (% p.a.)
- Bank name (for consolidation comparison)
2. Consumer loans (Ratenkredit) (one set of fields per loan)
- Purpose (auto, furniture, vacation, etc.)
- Outstanding balance (Restschuld) (€)
- Remaining term (months)
- Monthly payment (€)
- Effective interest rate (Effektivzins) (% p.a.)
- Does a Sondertilgungsrecht exist? If yes, how much per year?
3. Mortgage (Baufinanzierung)
- Outstanding balance (Restschuld) (€)
- Current nominal interest rate (Sollzins) (% p.a.)
- Repayment rate (Tilgungssatz) (% p.a.)
- Fixed-rate end date (Zinsbindungsende) (month/year)
- Sondertilgungsrecht: Yes/No, and if yes, what % of original loan amount per year?
- Monthly annuity payment (Annuität) (€)
- Original loan amount (Darlehenssumme) (€) — for Sondertilgung % calculation
- Is a Tilgungssatzwechsel permitted under the contract?
4. Credit cards (if revolving balance — rarely primary in Germany)
- Outstanding balance if NOT cleared monthly (€)
- Interest rate (% p.a.)
- Note: most German cardholders clear cards monthly via direct debit; flag if otherwise and treat like overdraft (Dispo)
5. Student loans (Bildungskredit / Studienkredite)
- Provider (KfW, Studentenwerk, private bank)
- Outstanding balance (Restschuld) (€)
- Interest rate (% p.a.)
- Remaining term (months)
- Monthly payment (€)
6. SCHUFA status
- Any known negative entries (Negativmerkmale)? (missed payments, debt collection, insolvency)
- If yes: when did the underlying event occur / when was it settled?
- Number of active credit lines / accounts
7. Income and payment budget
- Monthly net income (Nettoeinkommen) (€) — after tax, after social insurance
- Total monthly debt payments currently (sum of all above)
- Additional monthly amount available for accelerated repayment (€)
- Any lump sums expected (tax refund, bonus, inheritance)?
- Primary goal: fastest payoff / lowest total interest / psychological momentum / SCHUFA improvement
Debt Framework
Before analysis, read .claude/skills/shared/german-context.md for German debt context and benchmarks.
1. Debt Inventory and Prioritization
Rank all debts by the following German priority order (interest rate descending):
| Priority | Debt Type | Typical Rate | Action |
|---|
| 🔴 1 — Eliminate immediately | Overdraft (Dispositionskredit / Dispo) | 8–14% p.a. | Consolidate into consumer loan (Ratenkredit); reduce overdraft limit after |
| 🟡 2 — Repay early if possible | Credit card (revolving) | 15–20% p.a. | Treat exactly like overdraft (Dispo); consolidate or clear from savings |
| 🟡 3 — Accelerate with Sondertilgung | Consumer loan (Ratenkredit) | 3–8% p.a. | Use Sondertilgungsrecht to shorten term; compare Effektivzins |
| 🟢 4 — Maintain, optimize on refinance | Mortgage (Baufinanzierung) | 3–4.5% p.a. | Contractual payments only unless no higher-rate debt remains; use Sondertilgung if available |
| 🟢 5 — Lowest priority | Student loan (Bildungskredit / KfW) | 3–4% p.a. | Minimum payments only until all higher-rate debt cleared |
Method choice:
- Avalanche method (Hochzinsmethode): Pay minimums everywhere; all extra goes to highest-rate debt. Mathematically optimal — minimizes total interest.
- Snowball method (Schneeballmethode): Pay minimums everywhere; all extra goes to smallest balance. Higher total interest but faster psychological wins; recommended when motivation is a concern.
- Hybrid: Clear any debt with outstanding balance < €1,000 first (1–2 quick wins), then switch to avalanche method (Hochzinsmethode).
2. Debt Service Ratio (Schuldendienstquote)
Formula: Total monthly debt payments ÷ Monthly net income (Nettoeinkommen) × 100
| Range | Status | Meaning |
|---|
| < 30% | ✅ Healthy | Manageable; room to accelerate payoff |
| 30–40% | ⚠️ Tight | Tight but sustainable; review expenses |
| > 40% | 🚨 Critical | Urgent restructuring needed; consider nonprofit debt counseling (Schuldnerberatung) |
Important: The German debt service ratio (Schuldendienstquote) uses net income (Nettoeinkommen) (after tax and social insurance), not gross income. This is a stricter and more realistic measure than the US front/back-end DTI.
Housing-specific benchmark: Rent + utilities + mortgage payment (Baufinanzierung) should not exceed 35% of net income (Nettoeinkommen).
3. Overdraft (Dispositionskredit) Elimination
The overdraft (Dispo) is the most expensive commonly held debt in Germany (8–14% p.a.). It must be eliminated before any Sondertilgung on the mortgage or any new investment.
Strategy:
- Consolidate outstanding overdraft (Dispo) balance into a consumer loan (Ratenkredit) at a lower effective rate (Effektivzins) (target: 4–7%)
- Compare: ING Kredit, DKB Privatkredit, Check24 Kreditvergleich, Smava
- After consolidation: reduce the overdraft limit (Dispo-Limit) to a safety buffer only (maximum 1× net income), or eliminate the overdraft entirely
- Do not use the overdraft again for recurring expenses — repeated use signals a structural cash-flow problem
Consolidation math: Calculate the interest saving from day 1 of moving the balance from the overdraft rate to the consumer loan (Ratenkredit) rate over the payoff period.
4. Mortgage (Baufinanzierung) Optimization
Sondertilgungsrecht:
- Most German mortgage contracts include the right to make one or more annual extra repayments (Sondertilgungen) of 5–10% of the original loan amount
- Always use Sondertilgungsrecht if: (a) no higher-rate debt exists, and (b) the net return on alternative uses (savings, ETF) is lower than the Sollzins
- Each Sondertilgung directly reduces the outstanding balance, shortening the term or lowering subsequent payments
Tilgungssatzwechsel:
- Many contracts allow 1–2 rate changes per term (e.g., increase from 2% to 3% Tilgung)
- A higher Tilgungssatz increases the monthly payment but significantly reduces the total term and interest cost
- Check the loan contract (Darlehensvertrag) for permitted changes and notice periods
Anschlussfinanzierung planning:
- Begin comparing refinancing (Anschlussfinanzierung) rates at least 5 years before the fixed-rate end date (Zinsbindungsende)
- Forward loan (Forward-Darlehen): lock in a rate today for a future period (available 5 years ahead); small premium paid for rate certainty
- If the contract rate is significantly above market: calculate whether early repayment (Vorfälligkeitsentschädigung) is worth paying
- Vorfälligkeitsentschädigung: present value of the bank's foregone interest margin over remaining fixed-rate period, discounted at the reinvestment yield
- Rule of thumb: worthwhile only if market rate is ≥ 1.5% below contract rate AND remaining fixed-rate period > 3 years
- Platforms for comparison: Dr. Klein, Interhyp, Baufi24
5. SCHUFA Management
What affects the SCHUFA score:
- Negative entries (Negativmerkmale): missed payments, debt collection entries, insolvency proceedings, returned direct debits (Rücklastschriften)
- Number of active credit lines (fewer is better)
- Account stability: long-standing current account relationships help
- Address stability: frequent moves can flag instability
- Hard credit inquiries (Kreditanfragen): each stays 12 months; use soft inquiries (Konditionsanfragen) not hard inquiries (Kreditanfragen) when rate shopping
Deletion timeline:
- Paid negative entries (Negativmerkmale): deleted 3 years after full settlement (Tag der Erledigung)
- Insolvency proceedings: deleted 6 years after discharge (Restschuldbefreiung)
- Hard inquiries: deleted after 12 months
Improvement actions:
- Request free SCHUFA self-disclosure (Selbstauskunft) annually (bonitaetsauskunft.de — free once per year under DSGVO)
- Dispute any factually incorrect negative entries in writing with documentation
- Close old, unused credit lines and credit cards that are no longer needed
- Ensure all standing orders (Daueraufträge) and direct debits are covered — avoid returned direct debits (Rücklastschriften)
- Do not apply for multiple credits simultaneously; stagger applications by at least 3 months
6. Payoff Timeline Calculator
For each debt, calculate:
Months to payoff at current rate:
months = -log(1 - (outstanding_balance × monthly_rate) / monthly_payment) / log(1 + monthly_rate)
where monthly_rate = Effektivzins / 12 / 100
Total interest cost = (monthly_payment × months) - outstanding_balance
With extra monthly payment:
- Recalculate months and total interest with (monthly_payment + extra_payment)
- Interest saving = interest_cost_current − interest_cost_accelerated
- New debt-free date = today + accelerated months
Run this for all debts under both avalanche method (Hochzinsmethode) and snowball method (Schneeballmethode) to show the delta.
