What This Means

About Debt Consolidation Calculator

The Debt Consolidation Calculator analyzes multiple high-interest credit card and loan balances, comparing your current combined monthly payments and total interest against a single consolidated loan at a lower fixed rate.

Formula & Mathematical Calculation

Current Combined Monthly Payment = Sum ( Individual Debt Payments )

Consolidated Monthly Payment = Total Debt Balance × [ r_new (1 + r_new)^n ] / [ (1 + r_new)^n - 1 ]

Monthly Cash Flow Savings = Current Combined Payment - Consolidated Monthly Payment

Calculation Example

Consolidation Example ($25,000 Total Debt across 3 Credit Cards @ 22% APR, Min Payments = $750/mo): Consolidate into a 3-Year Personal Loan @ 10% APR → New Payment = $806.68/mo. Pays off 100% of debt in 36 months and saves $14,200 in interest!

Assumptions & Limitations

What the calculation assumes

  • Every value you enter is treated as an exact, known amount.
  • Rates and contributions are assumed to stay constant for the whole period unless the form asks for them separately.
  • Results use standard financial formulas and ignore fees, penalties and promotional terms that are not entered above.
  • Inflation, tax changes and market volatility are not modelled unless a field for them is provided.
  • Amounts are unit-agnostic: results are returned in the same currency you enter.

What it does not cover

  • Debt Consolidation Calculator produces estimates for education and planning, not a quote, offer or professional advice.
  • Real-world outcomes differ when fees, taxes, rounding rules or provider-specific terms apply.
  • Local regulations and tax rules vary by country and change over time; verify current rules for your jurisdiction.
  • Figures are only as accurate as the inputs you supply — check them before acting on the result.
  • For decisions with lasting financial impact, confirm the numbers with a qualified professional.

Frequently Asked Questions

Consolidation replaces multiple high-interest debts (e.g. 20-25% credit cards) with a single lower-interest loan (e.g. 8-12%), directing more of your payment toward principal.

The tool spreads your total debt across the number of months you choose at the new monthly rate, which is the new annual rate divided by 12. The result is a single fixed installment payment for the whole balance.

It subtracts the new consolidated payment from your current combined payment. When your current payment is larger, the gap is your monthly saving; when the consolidated payment is larger, your monthly outlay rises even though the balance is now a single loan.

Total interest equals the consolidated payment multiplied by the number of months, minus the amount you borrowed. Stretching the same balance over more months lowers each payment but raises the total interest paid.

At a zero percent rate the payment is simply the debt divided by the number of months, so every dollar reduces principal and the loan carries no interest.
