Three Debt Consolidation Savings Calculator
Combine three fixed-rate debts into one loan and compare the repayment cost after a financed origination fee.
Combine three fixed-rate debts into one loan and compare the repayment cost after a financed origination fee. Example result: consolidated monthly payment = $393.12. Compare your own inputs below. Estimates depend on the stated assumptions and are not a quote or forecast. Defaults are illustrative, not recommendations.
Your result
- Consolidated monthly payment
- $393.12
- Current modeled monthly payment
- $447.64
- Net total repayment saving
- $2,616.75
- Blended current nominal rate (%)
- 18.8%
With the example inputs, consolidated monthly payment is $393.12. Combining debts can simplify payments, but fees can erase the rate advantage. The blended rate is only a balance-weighted description; the actual comparison uses each loan’s payment separately.
How to use this three debt consolidation savings calculator
- Debt A balance: enter the amount in your selected currency. The worked example uses $5,000.00.
- Debt A annual rate: enter a percentage using 5 to mean 5%. The worked example uses 24%.
- Debt B balance: enter the amount in your selected currency. The worked example uses $7,000.00.
- Debt B annual rate: enter a percentage using 5 to mean 5%. The worked example uses 18%.
- Debt C balance: enter the amount in your selected currency. The worked example uses $3,000.00.
- Debt C annual rate: enter a percentage using 5 to mean 5%. The worked example uses 12%.
- Consolidation annual rate: enter a percentage using 5 to mean 5%. The worked example uses 10%.
- Shared repayment months: enter the quantity in months. The worked example uses 48 months.
- Financed origination fee: enter the amount in your selected currency. The worked example uses $500.00.
Start with figures from the same statement date or planning period. Calculate once, save scenario A, then change one assumption to understand its effect. The comparison shows B minus A; a positive difference means the result increased, which is not automatically better.
Formula and calculation method
Current payment = sum of separate PMT payments for A, B and C; new payment = PMT(total balance + fee, consolidation rate, shared months).
The calculator evaluates this relationship directly in your browser. The displayed precision is for readability and does not imply a guaranteed outcome. Time periods and rate conventions matter: use the exact units in each input label and avoid mixing monthly and annual values.
What the result means
Combining debts can simplify payments, but fees can erase the rate advantage. The blended rate is only a balance-weighted description; the actual comparison uses each loan’s payment separately.
Two worked examples
1. Illustrative planning scenario
Debt A balance = $5,000.00; Debt A annual rate = 24%; Debt B balance = $7,000.00; Debt B annual rate = 18%; Debt C balance = $3,000.00; Debt C annual rate = 12%; Consolidation annual rate = 10%; Shared repayment months = 48 months; Financed origination fee = $500.00.
Apply the stated formula with these inputs. Monetary examples use USD; percentages are divided by 100 inside the calculation. Intermediate calculations retain full precision and displayed amounts are rounded.
| Output | Calculated result |
|---|---|
| Consolidated monthly payment | $393.12 |
| Current modeled monthly payment | $447.64 |
| Net total repayment saving | $2,616.75 |
| Blended current nominal rate (%) | 18.8% |
2. Simplified calculation check
Debt A balance = $1,000.00; Debt A annual rate = 0%; Debt B balance = $2,000.00; Debt B annual rate = 0%; Debt C balance = $3,000.00; Debt C annual rate = 0%; Consolidation annual rate = 0%; Shared repayment months = 12 months; Financed origination fee = $120.00.
Apply the stated formula with these inputs. Monetary examples use USD; percentages are divided by 100 inside the calculation. Intermediate calculations retain full precision and displayed amounts are rounded.
| Output | Calculated result |
|---|---|
| Consolidated monthly payment | $510.00 |
| Current modeled monthly payment | $500.00 |
| Net total repayment saving | $-120.00 |
| Blended current nominal rate (%) | 0% |
The second example uses simpler inputs to make the arithmetic easier to check. It is also included in the automated regression suite. These examples illustrate the model and are not market averages, live offers or personalized advice.
Assumptions and limitations
All three debts are modeled over the same remaining term with fixed monthly accrual. No new purchases, changing minimums, penalties or collateral risk. Origination fee is financed.
Use this output to frame a question or compare consistent scenarios. Reconcile any decision involving an actual product, employment agreement or financial statement with its underlying documents. If a contract uses different rounding or timing, its result may differ from this estimate.
Frequently asked questions
Why not calculate all current debt at the blended rate?
Payment formulas are nonlinear in the rate. Summing each debt’s amortizing payment is more precise than using only a weighted average rate.
How do I interpret the consolidated monthly payment result?
Combining debts can simplify payments, but fees can erase the rate advantage. The blended rate is only a balance-weighted description; the actual comparison uses each loan’s payment separately.
What assumptions can change this estimate?
All three debts are modeled over the same remaining term with fixed monthly accrual. No new purchases, changing minimums, penalties or collateral risk. Origination fee is financed.
Can I compare two scenarios without creating an account?
Yes. Save scenario A, change one or more inputs to create scenario B, and compare each result with its difference. Neither scenario requires an account.
Can I use this calculator in another currency?
Yes. Select a display currency and enter every monetary input in that currency. This changes formatting only; it does not convert exchange rates or apply local laws. The static worked examples are in USD.
