About the Personal Loan Calculator

This free personal loan calculator helps people in the United States get a quick, private estimate before they talk to a lender, insurer, employer or advisor. There is no signup, nothing is stored on our servers and every result updates instantly in your browser.

How this calculator works

The calculator applies the amortization formula to the amount, APR and term to produce a fixed monthly payment and total interest cost.

Worked example

$10,000 at 12% APR over 36 months is about $332 per month and $1,957 in interest. Change any input above to see how the result moves, which is the fastest way to understand which factor matters most for you.

Tips to get a better result

Check for origination fees, which are deducted from proceeds. Use a personal loan to consolidate higher-rate debt only if the new APR is lower.

Key factors that change your result

Your credit score sets the APR, and origination fees (often 1% to 8%) are usually deducted from the amount you receive. Compare offers by APR, not just the monthly payment, and check for prepayment penalties before signing.

Accuracy and limits

Every calculator on Tools30 uses standard published formulas combined with average US market assumptions. Real offers depend on your credit profile, state, provider and personal circumstances, so treat the output as a starting point and confirm with an official quote or a licensed professional.
