Prosper is a US peer-to-peer lending marketplace where borrowers request personal loans and investors fund them in small slices called Notes, from $25 each. As borrowers repay, investors receive principal and interest. Since LendingClub closed its retail platform in 2020, Prosper is the main remaining way for US retail investors to fund consumer loans.

How Prosper works
Borrowers apply for unsecured personal loans, often to consolidate debt. Prosper assigns each loan a rating from AA, the lowest risk, to HR, the highest. Investors buy Notes in loans they choose, or use Auto Invest to spread money across loans by rating. Notes are offered under a prospectus filed with the SEC. Each month, borrower payments flow back to investors in proportion to their share.
Returns and fees
Prosper charges investors a 1% annual servicing fee on outstanding principal. Its SEC filings in mid-2026 listed a historical return range of 2.80% to 7.61% across ratings, as of May 31, 2026, based on payments received net of fees and losses. Higher-risk ratings offer higher interest but more defaults. Past returns don’t guarantee future results.
Risks to understand
Notes are not FDIC insured and have no Prosper or bank guarantee. If a borrower defaults, you lose some or all of that Note. Notes are not transferable and must be held until the loan ends, so your money is tied up for the loan term, typically three to five years. Prosper doesn’t verify every detail borrowers provide. Investing is open to residents of eligible states only.
Building a diversified portfolio
The key to P2P lending is spreading money thinly. Instead of $1,000 in four loans, $25 in forty loans means one default hurts far less. Many investors aim for 100 or more Notes across several ratings. Auto Invest makes this easy. Reinvest payments as they arrive to keep your money working.
Taxes
Interest from Notes is generally taxed as ordinary income. Prosper issues tax forms each year, and losses from charged-off loans can affect your tax position. Prosper offers IRA options through partners, which can defer taxes. Check with a tax adviser.
How Prosper compares with savings
A high-yield savings account pays less but is insured and liquid. Prosper may pay more, but you take on credit risk and lose easy access to your money. Many investors keep their emergency fund in savings and put only long-term money into P2P lending.
Starting small
Open an account, deposit a modest amount and spread it across many $25 Notes. Watch how payments, late loans and defaults show up over a few months before adding more. That hands-on view teaches more than any return figure.
Choosing ratings
Prosper’s ratings run from AA to HR. Lower ratings pay more interest but default more often, so the net return isn’t always higher. Many investors mix ratings, holding mostly middle grades with small slices of higher-risk loans. Auto Invest lets you set this mix once and apply it to every new deposit, which keeps your strategy consistent without daily attention.
Owen’s take
Prosper is a legitimate way to earn interest from consumer loans, and the $25 entry makes diversification easy. But it’s credit risk, plain and simple. I’d keep it to a small share of my investments, spread across many Notes, and never use money I might need before the loans finish.
Who it suits
It suits US investors in eligible states who want an alternative income stream and can lock money up for years. It suits less well anyone needing liquidity or who can’t stomach seeing some loans default.
