Debt Consolidation Calculator

Compare your current debt situation with an estimated consolidation loan. This calculator uses a standard amortized loan formula to estimate the new monthly payment, total repayment, total interest, and whether the new loan may lower or increase your total cost.

Estimated New Monthly Payment$0.00
Estimated Total Repayment$0.00
Estimated Total Interest$0.00
Monthly Payment Difference$0.00
Estimated Savings / Extra Cost$0.00

What This Calculator Estimates

This calculator estimates how a consolidation loan could change your monthly payment and total repayment. It compares your current monthly payment against a new amortized loan built from the debt amount, consolidation APR, term, and any origination fee you enter. Results are estimates for planning, not loan offers.

Formula / Method Used

The new loan estimate uses the standard amortized loan payment formula:

Payment = P x [r(1+r)^n] / [(1+r)^n - 1]

Estimated savings or extra cost compares the new total repayment to your current monthly payment multiplied by the same number of months.

Worked Example

Suppose you owe $18,000, currently pay $650 per month, and are considering a 36-month consolidation loan at 12.9% APR with a $500 origination fee.

You can then compare that projected repayment with your current payment pattern over the same 36-month period.

What the Result Means

A lower new payment may improve monthly cash flow, but the full comparison depends on total repayment and total interest. If the savings figure is positive, the estimate suggests the new loan costs less over the same number of months. If it is negative, the consolidation option may cost more overall.

Common Mistakes

Frequently Asked Questions

What does a debt consolidation calculator estimate?

It estimates what a new consolidation loan payment, total repayment, and total interest could look like based on the debt amount, new APR, and new loan term you enter.

Does a lower monthly payment always mean I save money?

No. A lower payment can still lead to a higher total repayment if the new term is longer or if fees are added.

How is the origination fee treated here?

This estimate adds the origination fee to the debt being financed so you can see the effect on payment and total repayment.

Can I rely on this for a final loan offer?

No. Use it for planning only. Actual loan offers may include different fees, APR structures, and repayment terms.
