Peer-to-peer (P2P) lending is a form of financing in which individuals lend money to other individuals or small businesses through an online platform rather than through a bank. The platform screens borrowers, sets terms and handles payments. The money, and most of the risk of not getting it back, comes from the individual lenders. P2P lending is also called social lending or crowd lending.

How P2P lending works

Each platform sets its own rates, terms and screening rules, but the process generally follows these steps:

1. The lender funds an account. An investor deposits money on the platform to be lent out.
2. The borrower applies. The applicant submits a financial profile, and the platform evaluates creditworthiness and assigns a risk category.
3. Pricing follows risk. The category sets the interest rate. Strong credit may earn rates below comparable bank rates; weak credit histories can face much higher rates.
4. Offers are made and accepted. The borrower accepts offers from one or more lenders. Some split a request into smaller pieces, so one loan may be funded by many investors.
5. Repayment runs through the platform. The platform sends the funds to the borrower, collects monthly payments and passes them to lenders.

Some platforms automate matching; others let lenders and borrowers negotiate, and some specialize in particular borrowers or loan purposes. Kiva, a nonprofit, lets people fund entrepreneurs in the U.S. and abroad, many without access to traditional lenders.

A worked example

Hypothetical figures for illustration only; they are not any platform’s terms.

An investor spreads $5,000 across 50 loans of $100 each. Assume each carries 12% annual interest and the platform charges lenders a 1% annual servicing fee on performing loans. Three borrowers default early, and the investor loses essentially all $300 lent to them.

• Interest from the 47 performing loans: 47 × $100 × 12% = $564
• Servicing fee: 1% × $4,700 = $47
• Default losses: $300
• Net result: $564 − $47 − $300 = $217, or about 4.3% on $5,000

This simplifies real loans, which amortize and return principal monthly, but the mechanics hold: fees and defaults come off the advertised rate. Had the $5,000 gone into a single loan that defaulted, the loss could have been nearly total. Spreading money across many small loans limits the damage from any one default but does not remove default risk.

For borrowers, the equivalent check is total cost. An origination fee deducted from the loan raises the effective cost above the quoted rate, so compare the APR, not headline rates.

Who uses P2P lending and why

P2P lending first served mainly people turned away by conventional lenders and students consolidating debt at a lower rate. It still reaches borrowers banks often overlook, including small business owners and entrepreneurs, though riskier profiles pay higher rates.

Borrowers with good credit use it to seek a lower rate than a bank offers. Lenders use it as an income investment that pays more than savings products, in exchange for credit risk.

Risks and limitations

Default risk. P2P borrowers can default more often than bank borrowers. Academic research on one major U.S. platform’s loans found default rates above 17%, while Federal Reserve data show delinquency rates on all loans at U.S. commercial banks have not exceeded 7.5% since 1986. Default and delinquency are different measures, but the gap points to meaningfully more credit risk.

Fees. Like banks, platforms may charge origination fees, late fees, bounced-payment fees and commissions, to borrowers, lenders or both. They reduce returns or raise borrowing costs.

Money is tied up. Committed cash returns gradually as borrowers repay on schedule, not on demand like a savings balance.

Who carries the risk of default

On a standard P2P loan, the lender carries the default risk, not the platform. The platform assesses and services the loan, but it is the investor’s money that goes unpaid. A bank deposit is different: the bank stands between depositors and borrowers, holds its own capital against losses (see the capital adequacy ratio), and eligible deposits are FDIC-insured. A P2P lender has no such buffer or government backstop. The loan agreement defines what protections, if any, apply.

What P2P lending is not

• P2P payments. Apps such as Venmo and PayPal move money between people. They transfer funds, but they do not originate loans or pay interest to the sender.
• Equity or rewards crowdfunding. Those models raise money in exchange for ownership or a product. P2P lending creates debt that the borrower must repay with interest.
• Payday loans. Payday loans are short-term, high-cost advances from a single lender. A P2P loan is typically an installment loan funded by individual investors.

How to invest in P2P lending

The direct route is to open a platform account, deposit funds and choose the borrower profiles to fund. Lower risk categories pay more modest rates; higher ones pay more but default more often. Before committing, read the fee schedule, the risk grades and what happens when a loan defaults.

The indirect route is buying stock in one of the publicly traded P2P lending companies. That is a bet on the platform’s business, carrying equity market risk rather than direct borrower credit risk.

The Bottom Line

P2P lending matters to investors seeking more income than savings accounts or CDs pay and to borrowers looking beyond banks. Lenders should expect fees and defaults to cut into advertised rates, spread money across many small loans, and remember that funds lack FDIC insurance and come back only as borrowers repay. Borrowers should compare the APR, since origination fees raise the true cost above the quoted rate.
