Personal Loan for Credit Card Debt? Payment Calculator

A personal-loan payment calculator estimates the monthly payment and total interest for a fixed-rate loan used to pay credit card balances. Enter the loan amount, annual percentage rate (APR), and term to see the estimate; it does not determine whether a lender will approve an application or whether moving debt is suitable for you.

Formula

The calculator uses a standard fixed-payment loan formula. It converts the annual APR to a monthly rate, calculates the payment needed to repay the principal over the selected number of months, rounds that payment to cents, and subtracts the borrowed amount from the sum of the scheduled payments to estimate interest.

• p is the loan amount, in dollars.
• apr is the annual percentage rate, entered as a percentage number; for example, enter 8 for 8%.
• yrs is the loan term in years.
• r is the monthly rate, calculated as apr ÷ 1,200.
• n is the number of monthly payments, calculated as yrs × 12.
• pmt is the monthly payment: p × r ÷ [1 − (1 + r)⁻ⁿ].
• int is estimated total interest: pmt × n − p.

The displayed payment is rounded to the nearest cent. Total interest uses that rounded payment multiplied by the full scheduled payment count, so the result is an estimate based on level monthly payments. A lender’s actual schedule can differ because of fees, payment dates, rounding conventions, or a different method of applying payments.

Worked Example

With the default inputs—$20,000 borrowed, 8% APR, and a five-year term—the calculation is:

1. Convert the APR to a monthly rate: 8 ÷ 1,200 = 0.0066667.
2. Find the payment count: 5 × 12 = 60 months.
3. Apply the payment formula: $20,000 × 0.0066667 ÷ [1 − (1 + 0.0066667)⁻⁶⁰] = $405.53 per month, rounded to cents.
4. Estimate total interest using the rounded payment: $405.53 × 60 − $20,000 = $4,331.80.

Thus, the calculator’s headline result is a monthly payment of $405.53, followed by estimated total interest of $4,331.80. These figures illustrate the formula; they are not a loan offer or a rate quote.

Assumptions

• The interest rate is fixed for the entire modeled term.
• Payments are equal monthly payments, made at the end of each monthly period.
• Interest accrues monthly using APR divided by 12.
• Fees, taxes, insurance, and other charges are not included; the calculator has no input for them.

Using a Personal Loan for Credit Card Debt

A personal loan used to pay credit card balances is often described as debt consolidation. In a typical arrangement, a borrower receives loan proceeds and uses them to pay one or more card accounts. The card balances are then replaced, in whole or in part, by the personal-loan balance. The calculator estimates the loan’s scheduled payment and interest, but it does not compare that result with the cost of keeping the card debt.

For a meaningful comparison, gather the current balance on each card, its APR, required payment, and any fees or promotional-rate end dates. Then compare the remaining cost under the card terms with the loan’s full repayment cost, including charges the loan formula omits. Make sure the amounts being compared cover the same debt and repayment period. A lower monthly payment alone does not establish a lower total cost: a longer term can reduce the payment while increasing the time interest accrues.

For example, a $20,000 loan at the default settings produces a modeled payment of $405.53 for 60 months. That number is useful only as a loan-payment estimate. To assess a proposed offer, replace the defaults with the amount, APR, and term shown in the lender’s disclosures, and account separately for any applicable origination charge or other cost. Do not treat the example APR as a current market rate.

How to Compare the Costs

APR and interest rate are related but are not always interchangeable in a real offer. APR is intended to express borrowing cost as an annual rate under the applicable disclosure method; a calculator that applies APR directly as a monthly rate is a simplified estimate. Check the lender’s payment schedule and disclosure for the actual payment, amount financed, fees, and total repayment figures. If a fee is deducted from the proceeds, the amount available to pay cards may be less than the loan’s stated principal.

Consider these questions when reviewing numbers:

• Will the loan proceeds cover all targeted card balances after any deductions?
• What is the total of scheduled payments, not just the monthly amount?
• Is the term longer or shorter than the period you expect to need to repay the cards?
• Does the estimate omit a fee, a variable-rate feature, or a payment timing detail?
• How will card accounts be used after balances are paid? New charges can add debt alongside the loan.

Paying cards with a loan does not itself remove the credit limits or prevent new card spending. If new balances accumulate while the loan remains outstanding, total debt can rise. Also, a loan may not cover every balance, and a partial payoff leaves some debt subject to the card’s terms.

Common Limitations and Alternatives

The formula assumes the borrower makes every payment on schedule and that the rate and payment structure remain unchanged. It does not model late or missed payments, extra principal payments, changing rates, lender-specific payment allocation, or a payoff quote on a particular date. It also cannot calculate card interest from a balance alone: card terms and transaction timing matter, so use the issuer’s statement or payoff information for a card-specific figure.

Other ways people evaluate card debt include continuing payments under existing card terms, asking an issuer about available repayment arrangements, or seeking information from a qualified nonprofit credit counselor. Each option has its own eligibility, costs, and effects, which this calculator does not assess. For any proposed transaction, verify the figures and terms directly in the relevant disclosures rather than relying on an estimate.

Frequently Asked Questions

Can I use a personal loan to pay credit card debt?
A personal loan may be used to pay card balances if the loan terms and lender allow it. Confirm how funds are disbursed and whether the amount available will cover the balances and any charges.

Will a personal loan lower my monthly payment?
It depends on the loan amount, APR, and term compared with the card payments. A longer term can produce a smaller scheduled payment but may mean paying interest for more months; this calculator does not compare your specific card accounts.

Does consolidating credit card debt save interest?
Not automatically. Compare the full costs over the repayment period, including applicable fees, and use the actual offer terms. A headline payment or APR alone is not enough to establish savings.

Does paying off a credit card with a loan close the account?
No. Paying a balance and closing an account are separate actions. Check the account’s status and terms with its issuer; this calculator does not model account changes.

What if the personal-loan payment is too high?
The calculator only estimates a payment for the inputs entered. You can model different terms to understand the arithmetic, but a lower modeled payment may involve a longer repayment period and more total interest. Ask the lender for its exact schedule and consider getting independent, qualified help with your situation.
