Quick Answer

Kasia (29) and Michał (31) from Kraków had 80,000 PLN (€18,600) in consumer debt — installment loans, a credit card, and a cash loan. In 3 years, they paid it all off using the avalanche method, built a 6-month emergency fund (36,000 PLN), and started investing. Today, 5 years later, they have a portfolio worth 120,000 PLN (€28,000). Here's how they did it.

Starting Point: 80,000 PLN in the Red

In 2020, Kasia and Michał sat at their kitchen table and listed all their debts for the first time:

Debt Amount Interest Rate Monthly Payment
Cash loan (Michał) 35,000 PLN 12.5% 1,050 PLN
Furniture installment loan 18,000 PLN 9.8% 520 PLN
Credit card (Kasia) 15,000 PLN 18.0% 450 PLN (minimum)
Electronics installment loan 12,000 PLN 10.5% 380 PLN
Total 80,000 PLN 2,400 PLN/month

Their Income and Expenses

  • Michał: warehouse manager, 6,200 PLN net/month (employment contract)
  • Kasia: marketing specialist, 5,800 PLN net/month (employment contract)
  • Combined income: 12,000 PLN net/month (~€2,800)
  • Expenses (excluding debt payments): 6,800 PLN/month (rent 2,800, food 2,000, transport 600, utilities 800, other 600)
  • Debt payments: 2,400 PLN/month
  • Remaining: 2,800 PLN/month — barely enough to get by

The problem? At minimum payments, paying off all debts would take over 5 years and cost an extra 22,000 PLN in interest.

Phase 1: The Attack Plan (Months 1–2)

Financial Audit

The first step was a complete budget breakdown. Kasia set up a spreadsheet (today they use Freenance) and tracked every expense for a month. The results were shocking:

  • 380 PLN/month on takeaway coffee
  • 290 PLN/month on subscriptions (Netflix, Spotify, HBO, CDA, YouTube Premium — duplicate accounts for everything!)
  • 450 PLN/month eating out
  • 200 PLN/month on impulse online shopping

Total recoverable: 1,320 PLN/month

The Cuts

  • Cafés → home coffee (good espresso machine for 400 PLN, saving 320 PLN/month)
  • Subscriptions → kept one Netflix account and Spotify Family (saving 190 PLN/month)
  • Eating out → Sunday meal prep (saving 350 PLN/month)
  • Impulse purchases → 48-hour rule (saving 150 PLN/month)
  • Michał started side hustling on Allegro (Poland's eBay) — selling unused items, then small services — extra 800 PLN/month

New monthly debt-attack budget: 2,400 (payments) + 1,810 (extra) = 4,210 PLN/month

Phase 2: The Avalanche Method in Action (Months 3–36)

Kasia and Michał chose the avalanche method — pay off the highest-interest debt first while making minimum payments on the rest.

Attack order:

  1. Credit card (18.0%) — paid off by month 9 (extra 1,810 PLN/month + minimum)
  2. Cash loan (12.5%) — paid off by month 21
  3. Electronics loan (10.5%) — paid off by month 28
  4. Furniture loan (9.8%) — paid off by month 34

Savings vs. Snowball Method

The avalanche method saved them ~4,200 PLN in interest compared to the snowball method. The choice isn't obvious — snowball gives faster "small wins" and motivation. But Kasia, an analyst by nature, preferred optimizing the numbers.

Staying Motivated

Months 12–24 were the hardest. Debt was shrinking, but slowly. What helped:

  • Progress tracking — a chart showing the declining debt balance
  • Mini-celebrations — after each debt was cleared, they went out for dinner (budget: 150 PLN)
  • A shared goal — they dreamed of a trip to Japan after becoming debt-free (they went!)

Phase 3: Emergency Fund (Months 35–42)

After clearing all debt, they had 4,210 PLN/month freed up. Instead of investing immediately, they built an emergency fund:

  • Target: 6 months of expenses = 6 × 6,000 PLN = 36,000 PLN
  • Timeline: 9 months (saving 4,000 PLN/month)
  • Where: savings account at their bank (easy access, ~5% interest rate)

The emergency fund gave them peace of mind. For the first time in years, they weren't afraid of unexpected expenses.

Phase 4: Investing (Month 43+)

With the emergency fund secured, Kasia and Michał started investing:

  • IKE (Kasia): VWCE ETF — maximum annual contribution (~23,000 PLN in 2024)
  • IKE (Michał): VWCE ETF — same
  • EDO bonds: 1,000 PLN/month (stable portfolio component)
  • Term deposit: 500 PLN/month (for larger purchases)

Monthly Allocation (2025):

  • IKE Kasia: 1,900 PLN
  • IKE Michał: 1,900 PLN
  • EDO bonds: 1,000 PLN
  • Term deposit: 500 PLN
  • Discretionary: 410 PLN

Results After 5 Years

Metric 2020 (Start) 2026 (Today)
Debt –80,000 PLN 0 PLN
Emergency fund 0 PLN 36,000 PLN
Investment portfolio 0 PLN 120,000 PLN
Net worth –80,000 PLN +156,000 PLN
Change +236,000 PLN

5 Lessons from Kasia and Michał

  1. List all your debts — you can't fight an enemy you don't know
  2. The avalanche method saves money — but pick the one you'll stick with
  3. Extra income accelerates everything — even 800 PLN/month makes a huge difference
  4. Emergency fund before investing — without one, a single crisis sets you back years
  5. Tracking progress motivates — visualizing declining debt is a powerful tool

FAQ

How long does it take to pay off 80,000 PLN in debt?

With an extra ~1,800 PLN/month above minimums using the avalanche method — about 3 years. With minimum payments alone — over 5 years and significantly more interest.

Avalanche or snowball method — which is better?

Avalanche (highest interest first) saves more money. Snowball (smallest balance first) gives quicker "wins." Mathematically, avalanche is superior, but the best method is the one you stick with.

Is it worth side hustling while paying off debt?

Absolutely. An extra 500–1,000 PLN/month can shorten repayment by a year or more. Even selling unused items on Allegro provides a quick cash boost.

When should you start investing after paying off debt?

First, build an emergency fund (3–6 months of expenses). Then invest. Investing without an emergency fund is risky — one crisis forces you to sell at a loss.

How can a couple manage finances together?

The key is transparency — both partners must see the full picture. A shared budget, regular "finance meetings" (Kasia and Michał do theirs every Sunday), and shared goals are essential.
