I put $500 into peer-to-peer lending in 2019. After three years, fees, defaults, and taxes, I cleared about $47. That’s a 3.1% annualized return — better than a savings account at the time, worse than an index fund, and significantly more work than either. Here’s what the actual data shows about P2P lending returns, default rates, and whether the risk-return trade-off makes sense for someone considering it now.
The short answer
Historical data from the two major US P2P lending platforms — LendingClub and Prosper — shows gross returns of 4–8% depending on the risk grade of loans you fund. After platform fees (typically 1%), borrower defaults (5–10% annually across all grades), and ordinary income taxes, real returns fall to 3–6% for most investors.
For context, that puts P2P lending somewhere between high-yield savings accounts and riskier bond funds — but with lower liquidity, higher tax friction, and more attention required than either alternative.
How P2P lending works
Peer-to-peer lending platforms connect individual borrowers — people looking for personal loans — with individual investors who fund those loans in exchange for interest payments. You deposit money into your account, browse loans the platform has underwritten, and choose which ones to fund in increments as small as $25.
The platform handles everything: credit checks, risk scoring, payment collection, and default management. You don’t communicate with borrowers. You select a risk grade (typically A through G, where A is highest credit quality and G is riskiest), fund loans in that category, and earn interest as borrowers make monthly payments.
The platform takes a fee — usually 1% annually — for this service. If a borrower defaults, you lose the remaining principal on that loan. There’s no FDIC insurance and no guarantee.
This is not peer-to-peer in the sense of you vetting anyone. You’re selecting from loans the platform has already screened and graded.
The platforms: LendingClub vs Prosper
As of 2026, two P2P lending platforms dominate the US market. Smaller platforms have largely shut down due to regulatory pressure and the high cost of SEC compliance.
| Platform | Ownership | Loans Originated (Lifetime) | Min. Investment | Avg. Borrower FICO | Annual Fee |
|---|---|---|---|---|---|
| LendingClub | Carlyle Group (acquired 2021) | ~$8.7B | $25 | 695–710 | 1% |
| Prosper | Private (Silverpeak/General Atlantic) | ~$16B | $25 | 680–710 | 1% |
LendingClub went public in 2014, then was acquired by private equity in 2021. It stopped accepting new peer-lending investors in 2020 and shifted focus to direct bank lending, though existing investor accounts remain active. According to SEC filings, the company’s transition away from marketplace lending means newer cohort data for retail investors is limited.
Prosper, founded in 2005, remains the older platform but is semi-closed in many states due to varying state lending regulations. If you’re in New York, North Carolina, or Utah, you’re likely restricted from investing on either platform.
The fee structures are identical: 1% annually on outstanding principal. The minimum investment is the same. The primary differences are borrower mix, historical default data, and regulatory standing in your state.
This is not a recommendation for either platform. These are the only two major options; neither is clearly “better” in a universal sense.
What the return numbers actually look like
Platform-published data shows historical gross returns ranging from 3% to 8% depending on loan grade and cohort year.
Based on investor performance data published by Prosper, the average net annualized return across all cohorts from 2009–2019 was 5.38%. LendingClub’s historical data shows similar ranges, though the company’s shift away from peer lending means newer cohort data is limited.
Breaking it down by strategy:
- Conservative (A-grade loans only): Historical net returns of 3–4% after fees and defaults. Lower default risk, lower yield.
- Balanced (A–C grade mix): Historical net returns of 5–6%. Moderate defaults, moderate yield.
- Aggressive (D–G grade mix): Historical net returns of 6–8%, but with significant volatility. In recession years, portfolios in this range saw drawdowns of 10–15%.
“Net return” here means after platform fees but before taxes. Taxes are where the friction gets real.
Current cohort performance (2024–2026)
The 2020 recession hit P2P lending hard. Default rates spiked across all grades as unemployment rose, and both platforms tightened underwriting standards significantly. Loans originated in 2024–2025 show modestly improved performance compared to 2020–2021 cohorts, but they’re still maturing — full loss curves won’t be visible until 2027 or later.
What we can observe from partial data: Prosper-originated loans from 2024 show year-one charge-off rates of 3–5% across mixed portfolios, slightly below the long-term average. LendingClub’s retail investor program remains mostly closed, so comparable data isn’t available. The takeaway: recent cohorts appear stable, but economic conditions matter more than platform choice. If unemployment rises or credit conditions tighten, expect default rates to climb again.
Investors deciding now are betting on loans originated in today’s credit environment, not the 2009–2019 baseline. That’s a meaningful distinction.
P2P lending default rates: the primary risk driver
Default rates vary widely by loan grade. This is the single most important number to understand, because it determines whether your returns exceed what you’d earn in a high-yield savings account.
From LendingClub’s historical cohort data and Prosper’s published performance reports:
- A-grade loans: 1–2% cumulative default rate
- D-grade loans: 5–7% cumulative default rate
- G-grade loans: 10–15% cumulative default rate
Prosper’s published data shows annual charge-off rates averaging 4–6% across all cohorts.
These are historical numbers. They represent past performance. If the economy enters a recession — or if borrower credit quality deteriorates — default rates can spike sharply. In 2020, default rates spiked significantly for lower-grade loans as unemployment surged.
When I funded loans in 2019, I split my $500 across A and B grades. Two loans defaulted early (both B-grade), wiping out about 8% of my principal before I’d earned much interest. That’s within the expected range, but it still stings when it happens to your small portfolio.
The risks they don’t lead with
Platform risk
If LendingClub or Prosper becomes insolvent, your loans are not FDIC-insured. Your claim would go into bankruptcy court. This is a low-probability event, but it’s not zero. The 2020 contraction — when LendingClub exited peer lending — showed how quickly regulatory and market conditions can shift.
Liquidity risk
You cannot easily sell your loans if you need cash. LendingClub and Prosper historically offered secondary markets, but those are mostly defunct as of 2026. If you invest $1,000 in 3-year loans and need that money in year two, you’re stuck or selling at a significant discount.
Early withdrawal programs exist on some platforms, but they buy back loans at below-market rates. You will lose money exiting early.
Concentration risk
If you build a small portfolio — say, 20 loans at $25 each — you’re exposed to individual borrower outcomes rather than diversified risk. One unexpected default can swing your annual return by several percentage points. Diversification across 100+ loans reduces this, but that requires more capital upfront.
Recession sensitivity
Consumer credit defaults spike in recessions. If you’re invested in P2P loans when unemployment jumps, your portfolio will take losses that correlate with the broader economy. You’re not diversifying away from market risk; you’re adding a different flavor of it.
Tax friction: the hidden return drag
Interest income from P2P lending is taxed as ordinary income, not capital gains. That means it’s taxed at the same rate as your salary.
According to IRS Publication 550, interest from peer-to-peer loans is reported on Form 1099-INT or 1099-OID. It’s fully taxable in the year you earn it, and losses from defaults are generally not deductible unless you’re operating as a business (which most individual investors are not).
Here’s what that looks like in practice:
A balanced portfolio earning 5% gross return (after fees and defaults) becomes:
- 3.8% after-tax for a 24% federal bracket investor
- 3.4% after-tax for a 32% federal bracket investor
- 3.15% after-tax for a 37% federal bracket investor
Add state income taxes — anywhere from 3% to 13% depending on your state — and high earners often end up with after-tax returns below 3%.
Compare that to a tax-advantaged account holding low-cost index funds, where you defer taxes until withdrawal and pay long-term capital gains rates (0%, 15%, or 20% depending on income). The tax treatment alone makes P2P lending less attractive than it appears on paper.
For high earners in the 32% or 37% federal brackets, the tax bite makes P2P lending nearly equivalent to a high-yield savings account after adjusting for risk.
How P2P lending compares to alternatives
The real question isn’t “what do P2P loans return?” — it’s “what do they return compared to simpler, more liquid options?”
| Investment Type | Typical Yield/Return | After-Tax (32% Bracket) | Liquidity | Risk Profile |
|---|---|---|---|---|
| High-Yield Savings | 4.5–4.8% APY | 3.1–3.3% | Daily | FDIC-insured, no principal risk |
| Short-Term Bond Funds | 3.2–4.0% yield | 2.2–2.7% | 1–2 days | Low volatility, interest rate risk |
| P2P Lending (Balanced) | 5.0% gross, ~4.0% net | 2.7–3.4% | 3–5 years (locked) | Default risk, platform risk, recession-sensitive |
| S&P 500 Index Fund | ~10% historical avg | ~8.5% (long-term cap gains) | Daily | High short-term volatility, long-term recovery |
P2P lending sits in an awkward middle: higher risk than savings or bonds, lower expected return than stocks, worse tax treatment than both bonds (if held in tax-advantaged accounts) and stocks (capital gains rates). The illiquidity means you can’t rebalance or exit without taking a loss.
The 2024–2026 rate environment makes this especially stark. According to Federal Reserve data, high-yield savings accounts offered 4.5–5.0% APY throughout 2024, with daily liquidity and FDIC insurance. A balanced P2P portfolio earning 5% gross and 3.4% after-tax underperforms a savings account on a risk-adjusted basis for most investors.
This doesn’t mean P2P lending has no place. It means the opportunity cost is higher now than it was in the 2009–2019 period when savings rates were near zero.
Is this “passive income”?
Technically, yes — you’re not trading hours for dollars. But it’s not “set and forget.”
You need to:
- Select loans or configure auto-invest settings (which may underperform manual selection)
- Monitor your portfolio quarterly to check default rates
- Reconcile tax forms annually (1099-INT for each loan, often dozens of forms)
- Track cost basis for partial defaults if you want accurate loss records
I spent about 6 hours total over three years managing my $500 P2P position: initial setup, two rebalances, and tax-time reconciliation. That’s not a lot, but it’s more than the zero hours I spend on my index fund.
This is not a criticism of the concept. It’s a clarification of what “passive” means here.
Who this might make sense for
I’m not recommending P2P lending. But there are scenarios where someone might allocate a small portion of their portfolio to it:
- You’ve maxed tax-advantaged accounts and want uncorrelated returns outside the stock/bond mix
- You’re comfortable with illiquidity and can lock up capital for 3–5 years
- You have enough capital to diversify across 100+ loans (reducing idiosyncratic risk)
- You understand that defaults are not theoretical — they will happen, and you’ll take losses
- You’re in a low enough tax bracket that ordinary income treatment doesn’t erase the return premium

FAQ
How much can you actually make on P2P lending platforms?
Historical data shows net returns of 4–8% before taxes, depending on loan grade. After taxes, most investors earn 3–6%. A balanced portfolio earning 5% gross becomes 3.4% after-tax for someone in the 32% federal bracket. Returns are not guaranteed and vary by economic conditions, loan selection, and default rates.
Is P2P lending safer than stocks?
Not necessarily. P2P loans don’t fluctuate daily like stocks, but they carry default risk, platform insolvency risk, and recession sensitivity. Index funds are more liquid, more diversified, and historically recover from downturns. P2P loans that default don’t recover.
Which platform has better returns, LendingClub or Prosper?
Historical performance is similar. Prosper’s published data shows 5.38% average net return (2009–2019 cohorts). LendingClub’s data is comparable but less current due to its 2020 exit from peer lending. Platform choice matters less than loan-grade selection and economic timing.
Can you lose money with P2P lending?
Yes. Borrower defaults are common (5–10% annually across all grades), and you lose the remaining principal on defaulted loans. In a recession, default rates can spike significantly. There’s also platform insolvency risk, though that’s lower probability.
How does P2P lending compare to high-yield savings accounts?
As of 2024–2026, high-yield savings accounts offer 4.5–4.8% APY with daily liquidity and FDIC insurance. P2P lending offers 4–5% net returns (after fees and defaults) but with 3–5 year lockup periods and default risk. After taxes, the gap narrows further — savings often win on a risk-adjusted basis.
I still have about $380 in active P2P loans as of 2026. I’m letting them mature rather than selling at a loss, but I haven’t added new capital since 2021. The returns didn’t justify the tax friction or the attention required compared to Best Robo-Advisor for Beginners: Real Comparison (2026) options that rebalance automatically and live in tax-advantaged accounts.
