Begin with matched documents, not advertised rates
A useful consolidation comparison needs two evidence sets from roughly the same date. For every debt the new loan would retire, obtain the payoff amount, applicable APR, and fixed payment used in the current-path scenario. For the proposed loan, obtain the transaction-specific interest rate, repayment term, origination fee, fee treatment, and disclosed APR. Do not compare a real current statement with a lender’s lowest advertised rate for an unknown borrower.
The first debt row is always visible. Add a second or third only when that account is included in the proposed payoff. The three-step form then separates current debts, rate and term, and fee handling so a person can reconcile each part before reading a conclusion.
How the current fixed-payment baseline works
Each current debt is amortized separately using its balance, entered APR, and fixed payment. The model adds one-twelfth of the annual rate each month, subtracts no more than the amount then due, and stops when the balance reaches zero. The baseline payoff time is the slowest of the included debts. Total current interest is the sum across those separate paths.
This is deliberately not a snowball or avalanche. When one debt finishes, its payment is not redirected to another debt. If the real plan keeps the total debt budget constant and rolls released payments forward, use the debt snowball calculator as a separate comparison. A consolidation loan should not appear to beat a weak baseline when the actual alternative is a disciplined rollover plan.
Interest rate and APR are not interchangeable inputs
The scheduled-payment formula needs the contract interest rate applied to principal. APR is a broader annualized cost measure that can include origination charges and other lender fees. The CFPB’s interest-rate and APR explanation distinguishes those measures and recommends comparing APR with APR rather than APR with an interest rate.
Enter the new loan’s contract rate in the required field. Record the disclosed APR in the optional field so it remains visible without being used twice—once as the payment rate and again as a separate fee. If the only number available is an advertised APR range, obtain a transaction-specific disclosure before treating the result as an offer comparison.
Model the fee the way the proceeds actually move
The calculator supports three explicit fee paths. A cash fee is paid separately and does not increase principal. A fee added on top increases the contract principal above the debt payoff amount. A fee deducted from proceeds also requires a larger gross principal when the remaining proceeds must fully retire the entered debts. In that deducted path, the calculator solves the gross amount so gross principal minus the percentage fee equals the payoff amount.
For example, simply requesting $10,000 with a 5 percent fee deducted would produce only $9,500 before any other deductions. To net $10,000 under this simplified percentage treatment, the gross contract principal must be higher. The result therefore displays net payoff proceeds, contract principal, fee, and interest attributable to the financed fee separately.
Actual lenders can calculate fees differently, cap them, deduct other charges, send proceeds directly to creditors, or approve less than requested. The CFPB notes that personal installment loans can include origination, documentation, optional insurance, and other fees and recommends checking required disclosures and comparing multiple offers. Use the calculator only after identifying every material charge.
Read the result in three layers
- Reconcile the current debts: number included, combined payoff amount, first-month interest, starting payments, slowest payoff, and total current interest.
- Reconcile the new loan: net proceeds, contract principal, rate, disclosed APR, fee treatment, payment, term, interest, and total cash outflow.
- Read payment, payoff-time, and borrowing-cost changes together. The outcome label states whether payment and cost move in the same or opposite directions.
The balance-weighted current APR is only a diagnostic summary of the entered rates. It does not replace separate amortization and does not predict a blended account rate. A lower new rate can still produce a higher total cost when the term is extended or fees are large.
A lower monthly payment can be a longer, costlier loan
The CFPB’s comparison of debt consolidation with other debt services warns that a lower payment may result from repaying over a longer period and that total fees and costs can make consolidation more expensive. The structured result makes that tradeoff explicit instead of presenting payment savings as the winner.
There are four broad mathematical outcomes: lower payment and lower cost; lower payment but higher cost; higher payment but lower cost; or higher payment and higher cost. None alone proves approval, affordability, or suitability. A lower-cost payment that cannot be made reliably is not a functioning payoff plan, while a higher-cost lower payment should be understood as purchasing cash-flow relief with more time or expense.
Reconcile net proceeds before any old account is considered paid
Obtain current payoff quotes rather than relying only on last statement balances. Accrued interest and payoff timing can change the amount needed. Confirm the new loan’s amount financed, any prepaid finance charge, proceeds paid to you or directly to creditors, first-payment date, and total of payments. Regulation Z’s closed-end credit disclosure framework distinguishes the amount financed, finance charge, APR, payment schedule, and total of payments.
After funding, continue required payments until each old creditor confirms the payoff and correct remaining balance. This calculator cannot verify delivery, timing, a short payoff, a prepayment charge, or an account that was intentionally excluded. A partial consolidation creates both old and new obligations and should be recalculated as such.
Collateral changes the downside, not just the rate
An unsecured personal loan and a loan secured by a home or vehicle are not equivalent risks. The FTC’s debt guidance explains that a consolidation loan may use unsecured credit or home equity and warns that missed payments on debt secured by a home can put the home at risk. The calculator does not convert foreclosure, repossession, lien, or loss-of-equity risk into dollars.
Do not choose secured consolidation solely because its rate is lower. Identify the collateral, default remedies, variable-rate possibility, closing costs, term, and any loss of protections attached to the original debt. Federal student loans, military protections, tax debts, medical debt, and debts already in collection can require questions this general loan model does not answer.
A consolidation loan is not credit counseling or settlement
A consolidation loan is new borrowing used to repay separate debts. A debt-management plan generally routes one payment through a counseling organization under agreements with creditors. Debt settlement attempts to resolve debts for less than owed and can involve very different risks. Do not enter a settlement proposal or counseling payment into this fixed-loan calculator as though it were an amortizing loan offer.
The CFPB’s credit-counseling guidance recommends asking about setup and monthly fees, written agreements, qualifications, and whether creditors accepted a proposed plan. If required payments are already unaffordable, contact creditors promptly and investigate carefully screened help rather than using an optimistic rate to make the calculator balance.
Prevent the old balances from returning
Paying off revolving accounts creates available credit but does not repair a recurring cash-flow deficit. New card purchases can leave both the consolidation loan and replacement card balances. Before closing, place the proposed payment into the monthly budget calculator, include irregular expenses, and decide how essential emergencies will be funded without immediately borrowing again.
The model assumes every included old balance stops changing except for interest and payment. It excludes new purchases, late fees, promotional expirations, variable rates, credit-score effects, taxes, optional products, and changes in income. Recalculate whenever the written offer or payoff quotes change.
