Quick Answer

To calculate personal loan payments: Use the formula M = P[r(1+r)^n]/[(1+r)^n-1], where M = monthly payment, P = principal, r = monthly interest rate, n = number of payments. For example, a $15,000 loan at 12% APR for 3 years results in monthly payments of $498.21 and total interest of $2,935.56.

Annual Percentage Rate (APR)

The yearly cost of the loan including interest and fees, expressed as a percentage. Personal loan APRs typically range from 6% to 36% based on credit score and lender.

Frequently Asked Questions

What credit score do I need for a personal loan?

Most lenders require a minimum 580-600 credit score, but rates improve significantly with higher scores. A score of 720+ qualifies for the best rates (6-12% APR). Scores 630-689 typically see 15-25% APR. Consider secured loans or credit-builder products if your score is below 580.

How much can I borrow with a personal loan?

Personal loan amounts typically range from $1,000 to $100,000, depending on your income, credit score, and debt-to-income ratio. Most lenders limit payments to 35-40% of monthly income. Your borrowing capacity increases with higher income and better credit history.

Should I use a personal loan for debt consolidation?

Yes, if you can qualify for a lower rate than your current debts and commit to not accumulating new debt. Personal loans work best for consolidating credit card debt above 15% APR. Calculate total interest savings and ensure the payment fits your budget before consolidating.

What's the difference between APR and interest rate?

Interest rate is the cost of borrowing money, while APR includes the interest rate plus all feeslike origination costs. APR gives you the true annual cost of the loan. Always compare APRs when shopping for loans, as a loan with a lower interest rate might have higher fees.

Can I pay off a personal loan early?

Most personal loans allow early payoff without penalties, which can save significant interest. However, some lenders charge prepayment penalties of 2-5% of the remaining balance. Always check loan terms before signing and factor this into your decision if you plan to pay off early.

How does a personal loan affect my credit score?

Initially, your score may drop 5-10 points from the credit inquiry and new account. However, using a personal loan for debt consolidation can improve your credit utilization ratio and payment history, potentially raising your score 20-40 points over 6-12 months with consistent payments.

What documents do I need to apply for a personal loan?

Common requirements include: proof of income (pay stubs, tax returns), bank statements, government-issued ID, and Social Security number. Some lenders may request employment verification or proof of assets. Online lenders often have streamlined processes requiring fewer documents.

What's the typical approval timeline for personal loans?

Online lenders often provide instant pre-approval and funding within 1-3 business days. Traditional banks may take 3-7 business days. Credit unions typically require membership but offer competitive rates. The fastest approvals come from existing banking relationships and borrowers with excellent credit.
