Is Peer-to-Peer Lending a Good Investment?

Peer-to-peer (P2P) lending platforms let you fund pieces of other people's personal loans directly, earning the interest a bank would normally collect. Advertised returns of 5-9% sound appealing next to a savings account, but the risk profile is closer to unsecured consumer debt than anything resembling a deposit account.

How It Actually Works

You deposit money into a platform (historically Prosper and LendingClub have been the largest U.S. names), which uses it to fund fractional shares of personal loans — often $25 slices spread across dozens or hundreds of borrowers to diversify risk. You earn the borrower's interest rate minus the platform's servicing fee, and you're repaid as borrowers make monthly payments.

The Real Risks

• Default risk: these are unsecured personal loans, often to borrowers who couldn't get a lower rate elsewhere — default rates run meaningfully higher than mortgage or auto loan defaults
• No FDIC insurance: unlike a savings account, this money is not insured if the platform or the loans fail
• Illiquidity: your money is locked into 3–5 year loan terms; early exit options (if they exist) come with steep discounts
• Platform risk: if the lending platform itself goes under, recovering your invested funds can be slow or incomplete

Realistic Returns After Defaults

Advertised rates are the interest rate on performing loans, not your net return. After factoring in defaults (which are baked into the model, not an edge case) actual historical net returns for diversified P2P portfolios have often landed closer to 3-6% — competitive with, but not dramatically better than, a diversified high-yield bond fund, and with considerably less liquidity.

Where It Might Make Sense

As a small satellite allocation (most advisors would say no more than 5-10% of your fixed-income allocation) for investors who understand and accept the illiquidity and default risk, spread across as many individual loans as the platform allows to reduce single-borrower concentration.
