Personal Loan Calculator
Calculate fixed monthly personal loan payments, cumulative interest, total payoff date, origination fees, and full annual/monthly amortization schedules.
Personal Loan Calculator
The Personal Loan Calculator can give concise visuals to help determine what monthly payments and total costs will look like over the life of a personal loan. Since most personal loans come with fees and/or insurance, the end cost for them can actually be higher than advertised. The calculator takes all of these variables into account when determining the real annual percentage rate, or APR for the loan.
• Provide the borrowed loan principal, interest rate, and repayment duration in years and months.
• Toggle fees/insurance to model origination costs and inspect full annual & monthly amortization schedules.

Balance & Payment Trajectory Over Time
Cumulative progressionWhat are Personal Loans?
A personal loan is an installment loan provided by banks, credit unions, or online lenders that gives borrowers a lump sum of cash upfront. Borrowers repay the loan in fixed monthly installments over a predetermined term—typically ranging between 12 to 84 months (1 to 7 years).
Unsecured vs. Secured
Most personal loans are unsecured, meaning you do not need collateral (like a home or car) to qualify. Approval and interest rates are determined primarily by credit scores, Debt-to-Income (DTI) ratio, and verifiable income.
Origination Fees & Real APR
Lenders frequently deduct an upfront origination fee (typically 1% to 8% of the loan amount) from the disbursed funds. While your nominal interest rate remains fixed, the origination fee increases the true Annual Percentage Rate (APR).
Debt Consolidation Power
Personal loans are widely used for debt consolidation—combining high-interest revolving credit cards (18%–29% APR) into a single fixed lower-rate installment loan (8%–14% APR) with a guaranteed debt-free payoff date.

Personal Loan Calculator — Frequently Asked Questions
Q1 What is a personal loan and how do fixed installments work? ▾
A personal loan is an installment loan provided by a bank, credit union, or online lender that gives you a lump sum upfront. You repay the principal plus interest in equal fixed monthly installments over a predetermined term (typically 12 to 84 months).
Q2 What is the difference between an unsecured and secured personal loan? ▾
An unsecured personal loan does not require any collateral; approval is based on your credit score, income, and debt-to-income ratio. A secured personal loan requires backing with an asset (such as a savings account, certificate of deposit, or vehicle), which usually provides lower interest rates.
Q3 How do origination fees affect the total cost of a personal loan? ▾
Origination fees (typically 1% to 8% of the loan amount) are upfront administrative fees charged by lenders and usually deducted directly from your disbursed loan proceeds. While your stated interest rate remains the same, an origination fee increases the true Annual Percentage Rate (APR).
Q4 Can I pay off my personal loan early to save on interest? ▾
Yes, most modern personal loan lenders do not charge prepayment penalties. Because interest accrues on your remaining unpaid balance, making extra principal payments reduces the total interest paid and accelerates your debt-free payoff timeline.
Q5 How does personal loan consolidation help with high-interest credit cards? ▾
By consolidating multiple high-interest revolving credit card balances (often 20% to 29% APR) into a single fixed-rate personal loan (typically 8% to 14% APR), borrowers can significantly lower their monthly payments, save thousands in interest, and establish a clear, structured payoff end date.
