Personal Loan Calculator — With Origination Fee & True Cost Breakdown

How Personal Loan Calculator Works

Monthly Payment = P × r(1+r)^n / ((1+r)^n − 1)

The standard loan amortization formula. P = principal (loan balance), r = monthly interest rate (APR divided by 12), n = number of monthly payments. Origination fees change the effective balance and your true APR in ways that are not always obvious from the stated interest rate.

Principal & Term

Loan Amount & Duration — The principal (P) is the total borrowed; the term (n) is the duration in months. If an origination fee is added to the balance, P increases accordingly. Together these variables determine your monthly payment and total interest cost.

r

Monthly Rate — The annual APR divided by 12. For example, a 12% APR equals a 1% monthly rate. This periodic rate is applied to the outstanding balance each month to determine the interest portion of the payment.

Origination Fee

Origination Fee Impact — When a fee is deducted from proceeds, you receive less cash but still repay the full loan amount — increasing your effective APR. When added to the balance, you pay interest on the fee for the entire loan term, further increasing the total cost.

How to Use

1. Enter the loan amount you are requesting from the lender.
2. Select the loan term — shorter terms have higher monthly payments but dramatically lower total interest.
3. Enter the APR (Annual Percentage Rate) quoted by your lender.
4. Select the origination fee type and amount. Most personal loans charge 1-8%.
5. Choose how the fee is handled — deducted from proceeds (most common) or added to the balance.
6. Review the monthly payment, actual cash received, and total cost of the loan including all fees.

Common Uses

• •Compare personal loan offers by calculating the true cost including origination fees, interest, and repayment term.
• •See how different origination fee structures — deducted from proceeds versus added to the balance — affect your net loan amount.
• •Determine whether a loan with a lower interest rate but higher origination fee is better than a no-fee loan with a higher rate.

Understanding the Result

Origination fees are a critical and often overlooked cost of personal loans. A 3% origination fee on a $20,000 loan is $600 — but if it is deducted from proceeds, you only receive $19,400 while repaying the full $20,000 plus interest. This raises your effective APR well above the stated rate. When the fee is added to the loan balance, you pay interest on the fee for the entire loan term, further increasing the total cost. Always compare loans on total cost rather than just the monthly payment or stated APR. The amortization schedule below shows every payment split between interest and principal reduction.

Frequently Asked Questions

What is a typical personal loan origination fee?

Personal loan origination fees typically range from 1% to 8% of the loan amount. Online lenders tend to charge more (3-8%), while credit unions and traditional banks may charge less or nothing at all. Some lenders advertise "no origination fee" but compensate with a higher interest rate. Always compare the APR — which is legally required to include qualifying fees — rather than just the interest rate when shopping for loans.

How does an origination fee affect my effective APR?

When an origination fee is deducted from your loan proceeds, you receive less money than you borrowed but still must repay the full loan amount plus interest. This effectively raises your true cost of borrowing. For example, a $20,000 loan at 11.5% APR with a 3% origination fee deducted means you receive only $19,400 but must repay the full $20,000 plus interest — raising your effective APR to approximately 13.5%. This calculator accounts for this and shows you the real cost.

Does my credit score affect my personal loan rate?

Yes — significantly. Borrowers with excellent credit (760+) typically qualify for the most competitive rates of 6-12%. Those with good credit (700-759) usually see rates of 12-18%. Fair credit (640-699) often results in rates of 18-28%. Below 640, rates can reach 30-36% or lenders may even decline the application entirely. Improving your credit score before applying for a personal loan can save thousands of dollars in interest on the same loan amount and term.
