How we calculate the consolidated monthly payment

The calculator uses the annuity formula: R = P × r × (1+r)^n / ((1+r)^n − 1), where P is the total consolidation amount, r = annual_rate / 12 and n is the number of instalments. Monthly saving = old payment − new payment.

Example: PLN 50,000 over 5 years at 7%

Consolidation loan PLN 50,000, 7% annual interest, 60 instalments: monthly payment ≈ PLN 990, total repaid ≈ PLN 59,400, total interest ≈ PLN 9,400. If the old total monthly payment was PLN 2,000, the monthly saving is about PLN 1,010.

Frequently asked questions

What is a debt consolidation loan?

A consolidation loan combines multiple debts (cash loans, credit cards, overdrafts) into a single loan with one lower monthly payment and often a longer repayment term, simplifying your finances.

When does consolidation make financial sense?

Consolidation is worth considering when the new interest rate is lower than the average rate on your existing debts, or when the total monthly payment exceeds your budget. Always compare total cost before deciding.

What formula does the calculator use?

The annuity formula: R = P × r × (1+r)^n / ((1+r)^n − 1), where P is the consolidation amount, r = annual_rate / 12 and n is the number of monthly instalments.

Does consolidation always reduce the total cost?

Not necessarily. A longer repayment term means more interest paid overall. A lower monthly payment may come with a higher total interest cost. Always compare total repayable amounts.

Which debts can be consolidated?

Banks typically consolidate cash loans, credit cards, car loans and revolving credit lines. Mortgage debt is usually consolidated separately as a "mortgage with consolidation" product.

What is the "old payment" field used for?

It represents your current total monthly payment across all consolidated debts. The calculator compares it with the new payment to show your monthly saving. The field is optional.
