Debt Consolidation Calculator — July 2026
Debt consolidation reduces the monthly installment by 30–50% but usually extends the repayment term — which can raise total interest by 15–30%. The kreddo.pl calculator compares the sum of your current installments against the new consolidation loan's installment and shows two key figures: monthly savings and total cost difference. Consolidation is worth it when current APR exceeds 15–18% or when total installments exceed 40% of income.
Add your current debts and see how much you would save monthly by merging them into a single loan.

Frequently asked questions
How does debt consolidation work?
A bank repays your existing loans (installment loans, credit cards, payday loans) with a single new loan at a lower monthly payment and a single due date. This reduces monthly pressure but usually extends the term — so total interest may grow.
When is consolidation worth it?
When you have 3+ debts with different terms and high APR (credit cards, payday loans), your current installments exceed 40% of income, you risk losing liquidity, or current APR exceeds 15–18%. It is not worth it if you are consolidating cheap mortgages or have little time left on the current loans.
By how much does the installment drop after consolidation?
Typically 30–50% lower, because the term extends from 2–3 to 5–8 years. With PLN 30k debt and current installments of PLN 1,200/month, a 7-year consolidation at 11% APR yields ~PLN 520 — but total cost rises from PLN 36k to ~PLN 43k.
Does consolidation hurt your BIK score?
No, as long as you service the new installment on time. Consolidation formally closes the old debts (with a "repaid" entry) and opens one new one. However, avoid late payments 3–6 months before applying — banks check recent credit history.
