Rates are illustrative averages for 2026. Your actual rate depends on credit score, lender, and loan specifics.
Personal Loans
Best for: Debt consolidation, home improvements, medical bills, or large purchases when you don't have collateral.
- Typical amounts: $1,000 – $100,000
- Terms: 1 – 7 years
- Rates: 7% – 15% (excellent credit: 7–10%; fair credit: 12–15%+)
- Collateral: None (unsecured)
- Funding speed: Often same-day to 1 week
Auto Loans
Best for: Buying a new or used car. The vehicle serves as collateral, so rates are typically lower than personal loans.
- Typical amounts: $5,000 – $100,000+
- Terms: 3 – 7 years (36 – 84 months)
- New car rates: 5% – 7% (excellent credit can get under 4%)
- Used car rates: 6% – 10%
- Collateral: The vehicle itself
⚠️ Watch out: Longer auto loan terms (72–84 months) lower your monthly payment but increase total interest dramatically and can leave you "underwater" — owing more than the car is worth.
Student Loans
Best for: Funding education. Federal loans offer income-driven repayment and forgiveness programs that private loans don't.
- Federal rates (2025-26): 5.50% (undergraduate), 7.05% (graduate), 8.08% (PLUS)
- Private rates: 4% – 15%+ depending on credit and cosigner
- Repayment: 10 – 25 years (federal); 5 – 20 years (private)
- Key advantage: Federal loans offer SAVE plan, PSLF, and deferment options
What to Look for in a Loan Calculator
A good loan calculator should show you more than just the monthly payment:
- Amortization schedule — see how each payment splits between principal and interest
- Total cost of borrowing — the full amount you'll pay over the life of the loan
- Extra payment impact — how paying more each month shortens your term and saves interest
- Side-by-side comparison — compare different rates, terms, or loan amounts

Open Loan Calculator →Frequently Asked Questions
What credit score do I need for the best rates?
For the lowest rates, you generally need a credit score of 740 or above. Scores between 670–739 get good rates, while scores below 670 may face higher APRs or require a cosigner.
Should I choose a shorter or longer loan term?
Shorter terms mean higher monthly payments but significantly less total interest. A 3-year auto loan at 6% on $30,000 costs $4,850 less in interest than a 6-year loan at the same rate. Choose the shortest term you can comfortably afford.
Is it better to get a personal loan or use a credit card?
For amounts over $3,000 with a payoff timeline beyond 6 months, a personal loan almost always wins. The average credit card APR is 21–24%, while personal loans range 7–15%. The fixed payment schedule also helps you pay it off faster.
