A personal loan for debt consolidation can replace several eligible debts with one installment loan, but whether it lowers your total cost depends on the loan’s APR, fees, term, and how you handle the old accounts. Use this calculator to estimate the monthly payment and total interest for a fixed-rate loan; enter the amount borrowed, APR, and term to see the results.
Formula
The calculator estimates a level monthly payment on a fixed-rate, amortizing loan. It uses the standard payment formula, followed by the amount paid over the full term minus the original principal:
- Monthly payment: M = P × r ÷ [1 − (1 + r)−n]
- Total interest: I = M × n − P
P is the loan principal in dollars, APR is the annual percentage rate entered as a percent, r is the monthly rate (APR ÷ 1,200), n is the number of monthly payments (years × 12), M is the monthly payment in dollars, and I is total interest in dollars. The calculator displays the formula’s results to two decimal places. Its total-interest calculation uses the unrounded payment expression shown above, so displayed figures can differ by a few cents from multiplying the displayed payment by the number of months.
Worked Example
Using the calculator defaults—$20,000 principal, 8% APR, and a five-year term:
- Convert APR to a monthly rate: r = 8 ÷ 1,200 = 0.0066667.
- Calculate the number of payments: n = 5 × 12 = 60.
- Substitute into the payment formula: M = 20,000 × 0.0066667 ÷ [1 − (1.0066667)−60] ≈ $405.53.
- Calculate total interest from the unrounded formula payment: I = M × 60 − 20,000 ≈ $4,331.78.
The estimated monthly payment is $405.53, and estimated total interest is $4,331.78. Calculations use full precision until the displayed results are rounded.
Assumptions
- The APR and monthly payment stay fixed throughout the term.
- Payments are made monthly, with the first payment one month after the loan begins.
- Interest compounds monthly at APR ÷ 12.
- Fees, taxes, insurance, and any costs of the debts being paid off are not included. The APR input should match the figure you are evaluating; ask the lender how any fees affect its quoted APR and proceeds.
How Debt Consolidation With a Personal Loan Works
Debt consolidation means combining multiple balances into a single repayment arrangement. With a personal loan, a borrower may use the proceeds to pay off debts such as credit-card balances or other unsecured loans. Some lenders send funds to creditors; others deposit the money for the borrower to distribute. The details depend on the lender, and the loan’s amount, APR, fees, and repayment term must be confirmed from its disclosure.
Consolidation changes how debt is repaid; it does not erase what is owed. A fixed installment payment can make the payoff schedule more predictable than balances with changing payments, but a longer term can mean paying interest for more months. The calculator estimates the new loan on its own. It does not compare it with your current debts or establish whether you qualify.
How to Evaluate the Cost
Compare the new loan’s full repayment cost with the remaining cost of the debts you plan to consolidate. Consider the APR, any origination or other fees, the term, and whether the loan amount covers the balances and associated costs. A lower monthly payment alone does not prove that borrowing costs less: the payment may be lower because the term is longer.
- Gather each debt’s current balance, APR, minimum payment, and any stated payoff amount.
- Ask the lender for the amount you would receive, all applicable fees, APR, payment, term, and total scheduled payments.
- Compare total remaining costs using consistent assumptions, including fees and the time needed to repay.
- Check whether the loan allows extra payments and how they are applied; confirm details with the lender.
For example, suppose a new loan reduces a monthly payment because it spreads repayment over more years. That may ease the month-to-month payment while increasing the number of payments and potentially the total interest. Conversely, a shorter term can raise the monthly payment while reducing the time interest accrues. This calculator helps show the relationship between principal, APR, and term, but cannot assess your household budget or other financial circumstances.
Common Risks and Alternatives
A key risk is paying off revolving balances with a loan and then adding new charges to the same accounts. That can leave someone with both the installment loan and renewed card balances. A written payoff plan, checking creditor balances after payments post, and avoiding new borrowing where possible can help prevent confusion; these steps do not guarantee a particular financial result.
Other approaches include continuing to repay debts separately, contacting creditors to ask about available payment arrangements, or seeking information from a qualified nonprofit credit-counseling organization. Each option has different costs and conditions. Do not assume that a consolidation loan changes the terms of debts that are not paid off, or that it will remove late-payment history or other account information.
Be cautious of unsolicited promises to eliminate debt, pressure to act immediately, requests for upfront payment before explaining services, or demands to stop communicating with creditors without a clear explanation. Verify the organization and understand all fees and terms before sharing sensitive financial information. This is general educational information, not individualized financial advice.
Frequently Asked Questions
Does a personal loan for debt consolidation lower the monthly payment?
It can, depending on the amount, APR, fees, and term. A longer term may lower the payment while increasing the total interest or total repayment amount.
Will debt consolidation save me money?
Not necessarily. Compare the new loan’s total scheduled payments and fees with the remaining cost of the debts being paid off. The calculator estimates the loan, not the cost of your existing debts.
Can I consolidate credit-card debt with a personal loan?
Some personal loans can be used to pay credit-card balances, but permitted uses and payment arrangements vary. Confirm with the lender whether it will pay creditors directly or send funds to you.
Does consolidating debt erase it or improve my credit?
No. The balances are repaid only if the loan proceeds reach the creditors and the payments clear. Credit outcomes depend on individual circumstances and reporting practices; this calculator does not predict them.
What should I enter as the loan amount?
Use the amount you expect to borrow, including any financed fees if applicable. The amount disbursed to creditors may differ from the loan principal if fees are deducted or added; verify the figures in the lender’s disclosure.
