About this Personal Loan Calculator
A personal loan is a lump-sum specifically used for one-off expenses like medical bills, weddings, or debt consolidation. Unlike credit cards, they have a fixed end date. This tool helps you visualize the long-term cost of borrowing.
Who this calculator is for
- Borrowers comparing debt-consolidation or emergency-expense loan offers.
- Anyone who wants to test whether a fixed installment payment fits their monthly budget.
- Users deciding between a personal loan and other borrowing options before applying.
When to use it
- Use this calculator when you have a quoted APR and need a fast monthly payment estimate.
- Compare multiple repayment terms to see the tradeoff between cash flow and total interest.
- Review the result alongside your DTI to see how a new personal loan could affect overall borrowing capacity.
How to use this calculator
- Enter the Loan Amount you wish to borrow.
- Input the estimated Annual Interest Rate (APR). This depends on your credit score (typically 6% to 36%).
- Select the Loan Term in years. Shorter terms mean higher monthly payments but less interest paid overall.
Key assumptions
- The model assumes a fixed-rate installment loan with equal monthly payments over the full term.
- APR is treated as the effective annual borrowing rate for the schedule and no separate origination fee line is modeled.
- Payments start immediately and remain unchanged through payoff.
