Prosper is a peer-to-peer personal loan marketplace offering $2,000-$50,000 loans with fixed rates from 6.99% APR. SEC-registered, BBB A+ accredited since 2012, with WebBank as lending partner.
Editorially reviewed by Harvey Brooks
Prosper Marketplace was founded in 2005 as one of the first peer-to-peer lending platforms in the United States. Headquartered at 221 Main Street in San Francisco, the company connects borrowers seeking personal loans ($2,000-$50,000) with individual and institutional investors who fund those loans. WebBank, a Utah-chartered FDIC-insured industrial bank, is the issuing lender for all Prosper loans.
Prosper's personal loans carry fixed APRs from 6.99% to 35.99% with 3-year or 5-year terms. Origination fees range from 1% to 9.99%. The platform uses its own proprietary credit model alongside traditional credit scores to assess borrowers. Rate checks use soft credit pulls that don't affect credit scores. Loans can be used for debt consolidation, home improvement, medical expenses, auto expenses, and other purposes.
Prosper is notable for being SEC-registered — its loan notes are registered securities, making it one of the most heavily regulated personal lending platforms. The company has facilitated over $26 billion in loans since inception and is NMLS-registered (#111473). It holds BBB A+ accreditation (since 2012) and maintains a Google rating of 2.1/5 from 71 reviews (reflecting its San Francisco office, not overall service quality).
Key caveats: Prosper has a complex regulatory history including a 2008 SEC cease-and-desist order for selling unregistered securities, a $10M class action settlement in 2013, a $3M SEC settlement in 2019 for misleading investor return data, and a significant data breach in 2025 affecting up to 17.6 million records (litigation pending). APRs reaching 35.99% and origination fees up to 9.99% place it at the higher end of personal loan costs for subprime borrowers.
Borrowers comparing personal loan lenders should consider the full range of borrowing and credit-building options available. Those with damaged credit may find personal loans for bad credit more accessible, though typically at higher rates. Debt consolidation loans are specifically designed to combine multiple high-interest balances into a single payment with a lower rate. For credit rebuilding alongside borrowing, credit builder loans and secured credit cards offer structured paths to improving scores over time. Consumers dealing with existing negative items should also explore credit repair services to address inaccuracies before applying, as a cleaner credit report often unlocks better loan terms.

CreditDoc Diagnosis
Prosper is one of the original peer-to-peer lending platforms with over $26B in loans facilitated since 2005. Its SEC registration and BBB A+ accreditation provide meaningful regulatory oversight. Best for borrowers with good credit seeking debt consolidation, though origination fees (up to 9.99%) and APRs (up to 35.99%) are high-end. The 2025 data breach affecting 17.6M records is a significant concern — check their security disclosures before applying.

Read guide →New to credit and lending? Here are the key terms used on this page, explained in plain language with real-number examples.
The total yearly cost of borrowing money, including the interest rate plus any fees the lender charges. Think of it as the 'true price tag' on a loan.
Lenders must show APR by law (Truth in Lending Act) because the interest rate alone can hide fees. Comparing APR across lenders is the most reliable way to find the cheapest loan.
Example
You borrow $10,000 at 6% interest for 3 years, but there's a $300 origination fee. The interest rate is 6%, but the APR is 6.9% because it includes that fee. You'd pay $304/month and $946 total in interest.
The percentage a lender charges you for borrowing their money, calculated on the amount you still owe. It's the lender's profit for taking the risk of lending to you.
Even a 1% difference in interest rate can cost you thousands over a loan's life. Lower rates mean less money out of your pocket.
Example
On a $20,000 car loan for 5 years: at 5% you pay $2,645 in interest. At 8% you pay $4,332. That 3% difference costs you $1,687 extra.
Interest calculated on both the original amount borrowed AND the interest that's already been added. It's 'interest on interest' — and it makes debt grow faster than you'd expect.
Credit cards and many loans use compound interest. If you only make minimum payments, compound interest is why a $3,000 balance can take 15 years to pay off.
Example
You owe $1,000 at 20% annual interest compounded monthly. After month 1 you owe $1,016.67. Month 2, interest is charged on $1,016.67 (not $1,000), so you owe $1,033.61. After 1 year without payments: $1,219.
Interest calculated only on the original amount borrowed, not on accumulated interest. It's the simpler, cheaper type of interest.
Most auto loans and some personal loans use simple interest. Paying early saves you money because interest is only on what you still owe.
Example
You borrow $5,000 at 8% simple interest for 2 years. Interest = $5,000 x 0.08 x 2 = $800 total. You repay $5,800. With compound interest, you'd owe more.
An interest rate that stays the same for the entire life of the loan. Your monthly payment never changes.
Fixed rates protect you from market changes. If rates go up, your payment stays the same. The tradeoff: fixed rates are usually slightly higher than starting variable rates.
Example
You get a 30-year mortgage at 6.5% fixed. Whether rates rise to 9% or drop to 4% over the next 30 years, your payment stays at $1,264/month on a $200,000 loan.
An interest rate that can go up or down over time, usually tied to a benchmark like the prime rate. Your monthly payment changes when the rate changes.
Variable rates often start lower than fixed rates to attract borrowers, but they can increase significantly. Many people who got hurt in the 2008 crisis had adjustable-rate mortgages.
Example
You start with a 5/1 ARM mortgage at 5.5%. For the first 5 years you pay $1,136/month on $200,000. Then the rate adjusts to 7.5%, and your payment jumps to $1,398/month.
The original amount of money you borrowed, before any interest or fees are added. It's the 'real' amount of your debt.
Your interest is calculated on the principal. Paying extra toward principal (not just interest) is the fastest way to reduce your total cost and pay off a loan early.
Example
You borrow $25,000 for a car. That $25,000 is your principal. Your first payment of $450 might split as $150 toward interest and $300 toward principal, bringing your balance to $24,700.
How long you have to repay the loan, measured in months or years. A shorter term means higher monthly payments but less total interest paid.
Longer terms feel more affordable monthly but cost much more overall. A 30-year mortgage costs almost double in interest compared to a 15-year mortgage on the same amount.
Example
Borrowing $200,000 at 6.5%: A 15-year term costs $1,742/month ($113,561 total interest). A 30-year term costs $1,264/month ($255,088 total interest). You save $141,527 with the shorter term.
The process of paying off a loan through regular payments that cover both principal and interest. Early payments are mostly interest; later payments are mostly principal.
Understanding amortization explains why paying extra early in a loan saves the most money — you're reducing the principal that interest is calculated on.
Example
Month 1 of a $200,000 mortgage at 6%: your $1,199 payment splits as $1,000 interest + $199 principal. By month 300: only $47 goes to interest and $1,152 goes to principal.
A large lump-sum payment due at the end of a loan, after a period of smaller monthly payments. The loan isn't fully paid off by the regular payments — the balloon settles it.
Balloon payments make monthly payments look affordable but create a financial cliff. If you can't pay or refinance at the end, you could lose your home or asset.
Example
A 5-year balloon mortgage on $200,000: you pay $1,054/month (as if it were a 30-year loan), but after 5 years you owe a balloon of $186,108 all at once.
A fee some lenders charge if you pay off your loan early. The lender loses the interest they expected to earn, so they penalize you for leaving early.
Always ask about prepayment penalties before signing. They can trap you in a high-rate loan even if you find a better deal to refinance into.
Example
Your mortgage has a 2% prepayment penalty for the first 3 years. If you refinance after year 2 on a $200,000 balance, you'd owe a $4,000 penalty fee.
A one-time fee the lender charges to process and set up your loan. It covers their costs for underwriting, verifying your information, and preparing paperwork.
Origination fees are usually 1-8% of the loan amount and are often deducted from your loan proceeds — so you receive less than you borrowed.
Example
You're approved for a $10,000 personal loan with a 5% origination fee. The lender deducts $500 upfront, so you receive $9,500 in your bank account but owe $10,000 plus interest.
An asset you pledge to the lender as security for a loan. If you stop paying, the lender can seize and sell that asset to recover their money.
Secured loans (with collateral) have lower interest rates because the lender has less risk. But you could lose your home, car, or savings if you default.
Example
A mortgage uses your house as collateral. A car loan uses your vehicle. A title loan uses your car title. If you miss payments, the lender can foreclose or repossess.
A person who agrees to repay your loan if you can't. They're equally responsible for the debt, and their credit is affected by your payment behavior.
Cosigning helps people with thin credit get approved or get better rates. But it's a huge risk for the cosigner — they're on the hook for the full amount if you default.
Example
A parent cosigns their child's $30,000 student loan. The child stops paying after 6 months. The parent is now legally required to make the payments or face collections, lawsuits, and credit damage.
When you fail to repay a loan according to the agreed terms — usually after 90-180 days of missed payments. It's the point where the lender gives up on collecting normally.
Default triggers severe consequences: credit score drops 100+ points, the debt may be sent to collections, you could be sued, and your wages or assets could be seized.
Example
You miss 4 consecutive car payments. The lender declares your loan in default, repossesses your car, sells it at auction for $8,000, and you still owe the remaining $5,000 (called a deficiency balance).
Replacing your current loan with a new one, usually at a lower interest rate or with different terms. The new loan pays off the old one.
Refinancing can save thousands if rates drop or your credit improves. But watch for fees — a $3,000 refinancing cost needs to be offset by monthly savings.
Example
You have a $180,000 mortgage at 7.5% ($1,259/month). You refinance to 6% ($1,079/month), saving $180/month. With $3,000 in closing costs, you break even in 17 months.
The process where a lender evaluates your finances — income, debts, credit history, assets — to decide whether to approve your loan and at what rate.
Understanding what underwriters look for helps you prepare a stronger application. They check your DTI ratio, employment stability, credit score, and the asset's value.
Example
You apply for a mortgage. The underwriter reviews your pay stubs (income), bank statements (savings), credit report (history), and orders an appraisal (home value). This takes 2-4 weeks.
A secured loan is backed by collateral (an asset the lender can seize). An unsecured loan has no collateral — the lender relies only on your promise to repay.
Secured loans have lower rates because the lender has less risk. Unsecured loans (credit cards, personal loans) charge higher rates but you don't risk losing an asset.
Example
Auto loan (secured): 6% APR — lender can repossess your car. Personal loan (unsecured): 12% APR — no collateral, but higher rate. Same borrower, same credit score.
A charge added to your account when you miss a payment deadline. Most credit cards charge $29-$41 per late payment, and many loans have similar penalties.
The fee itself hurts, but the real damage is to your credit score. A payment 30+ days late stays on your credit report for 7 years and can drop your score 60-110 points.
Example
Your credit card payment of $150 is due March 1. You pay on March 18. The bank charges a $39 late fee. If it's 30+ days late, it gets reported to credit bureaus and your 760 score drops to 670.
The total cost of borrowing, including interest and all fees combined. The lender must disclose this number under the Truth in Lending Act.
The finance charge gives you the total dollar amount you'll pay beyond the principal. It's the clearest picture of what a loan actually costs you.
Example
You borrow $15,000 for 4 years at 8% APR with a $450 origination fee. Finance charge: $2,612 (interest) + $450 (fee) = $3,062 total. You repay $18,062 for a $15,000 loan.
A federal law requiring lenders to clearly disclose loan terms — APR, finance charge, total payments, and payment schedule — before you sign. No hidden costs allowed.
TILA gives you the right to compare loan offers on equal terms. Every lender must show costs the same way, making it easier to find the best deal.
Example
Two lenders offer you a car loan. Lender A says '5.9% rate.' Lender B says '6.2% APR.' Under TILA, both must show APR — Lender A's true APR with fees is actually 6.8%, making Lender B cheaper.
The percentage of your monthly gross income that goes toward paying debts. Lenders use it to judge whether you can afford another loan payment.
Most lenders want DTI below 36% for personal loans and below 43% for mortgages. Above that, you're considered overextended and likely to be denied.
Example
You earn $5,000/month gross. Your debts: $1,200 mortgage + $300 car + $200 student loans = $1,700/month. DTI = 34%. A new $400/month loan would push you to 42% — risky for lenders.
Combining multiple debts into one single loan with one monthly payment, ideally at a lower interest rate. It simplifies repayment and can reduce total interest.
Consolidation works best when you get a lower rate than your existing debts. But it doesn't reduce what you owe — and extending the term can mean paying more total interest.
Example
You have: $5,000 at 22% (credit card), $3,000 at 18% (store card), $2,000 at 25% (payday loan). A $10,000 consolidation loan at 11% saves you ~$2,100 in interest over 3 years.
