P2P Loans Explained: How They Work for Investors

What a P2P loan is (and what this guide covers)

A peer-to-peer loan is a debt instrument originated by a licensed lending company - the originator - and sold to retail investors through an online platform. The borrower can be a consumer, a small business, or a property developer. Investors receive the loan's interest payments and principal repayment over a fixed term, typically 6 to 60 months. This guide focuses on the loan itself as a financial entity: its structure, terms, collateral, repayment mechanics, and the step-by-step process when payments stop.

For a broader introduction to P2P lending as an investment category, including how platforms work and how to open an account, see our pillar guide. Here we answer the question investors ask after signing up: "How do I read a loan listing, and what am I actually buying?"

Secured vs unsecured P2P loans

Every P2P loan falls into one of two categories based on whether the borrower pledges collateral.

Secured loans are backed by an asset - real estate, equipment, inventory, or invoices - that the lender can seize and liquidate if the borrower defaults. Maclear originates secured SME loans against machinery, commercial property, and factored invoices; InRento finances buy-to-let property purchases with a first-lien mortgage as collateral. Secured loans typically offer 8-12% annual interest because the collateral reduces loss-given-default: if the borrower stops paying, the platform or originator can sell the asset and distribute proceeds to investors. The key metric is loan-to-value ratio (LTV) - a EUR 60,000 loan on a EUR 100,000 property is 60% LTV, meaning a 40% value cushion before investors face losses if the property sells below appraisal.

Unsecured loans rely solely on the borrower's creditworthiness - no collateral can be seized. Consumer loans for debt consolidation, home improvement, or medical expenses are almost always unsecured. Because recovery rates on defaulted unsecured loans average 10-30% after years of collection work, platforms compensate investors with higher interest: Nectaro pays 14.9% on unsecured consumer notes, and Robocash offers 9-13% on short-term consumer loans with 60-day buyback guarantees. The buyback guarantee - where the originator repurchases late loans - substitutes for collateral, shifting credit risk from the borrower to the originator.

How to choose between secured and unsecured

Secured loans suit investors prioritising capital preservation: the collateral provides a recovery floor, and realised yields on platforms like Maclear (14.5-14.9% on secured SME loans) and InRento (~11.8% on buy-to-let) are close to advertised rates because defaults are manageable. Unsecured loans with buyback guarantees suit investors seeking predictable cash flow: the buyback mechanism delivers the advertised yield as long as the originator remains solvent, but introduces originator concentration risk - if the originator fails, every loan in your portfolio backed by that originator becomes a workout case.

Platforms like Mintos offer both: you can filter loan listings by "secured" or view the buyback-guarantee toggle. Compare LTV on secured listings (lower is safer) and check the originator's financial statements on unsecured buyback loans (positive equity and profit margins indicate buyback capacity).

Loan term lengths and what they mean

P2P loan terms range from 1 month to 10 years, with distinct risk-return profiles.

Short-term loans (1-12 months) dominate consumer lending: payday-style loans, invoice financing, and seasonal working capital. Robocash's median loan term is 30 days; Maclear's invoice discounting loans run 60-120 days. Short terms mean faster capital return and lower exposure to borrower life events (job loss, business failure), but require constant reinvestment to avoid cash drag. If your platform's auto-invest queue is slow, capital sits idle between loan maturities.

Medium-term loans (12-36 months) are the sweet spot for most investors. Consumer instalment loans, equipment leasing, and small-business term loans cluster here. PeerBerry's leasing loans average 24 months; InRento's buy-to-let loans are typically 24-36 months. Medium terms balance reinvestment friction with manageable credit risk: a 24-month loan exposes you to two years of borrower performance, but you are not locked in for five.

Long-term loans (36+ months) appear in real-estate development (18-36 months for a build-and-sell project) and buy-to-let refinancing (up to 120 months). Longer terms amplify interest-rate risk - if market rates rise, your 5% loan looks unattractive and may trade at a discount on the secondary market - and increase the probability of a credit event over the loan's life. Platforms like Crowdpear offer 12-24 month real-estate development loans; investors who prefer 36+ month exposure can hold buy-to-let loans on InRento, accepting the liquidity trade-off for slightly higher yields.

Interest structures: fixed rate, amortising vs bullet

P2P loans carry a fixed annual interest rate set at origination. A 12% APR loan on EUR 10,000 generates EUR 1,200 gross interest over 12 months, paid monthly. Platforms display the gross APR; investors net the rate minus the platform fee (typically 1%) and any payment-processing fees. Maclear charges 0% investor fees, so the advertised 14.5-14.9% is the net yield after loan defaults; Mintos charges 1% on interest earned, reducing a 10% loan to 9% net.

Two repayment structures govern how principal returns:

Amortising loans repay principal and interest in equal monthly instalments. A EUR 10,000 loan at 12% APR over 12 months pays EUR 888.49 per month (EUR 100 interest in month 1, EUR 788.49 principal; by month 12, EUR 8.77 interest, EUR 879.72 principal). Your outstanding exposure declines each month. This structure dominates consumer lending - Nectaro, Robocash, and Lendermarket loans are 95%+ amortising. The benefit: capital returns steadily, reducing risk if the borrower's situation deteriorates; the drawback: reinvestment drag if you cannot immediately redeploy the monthly principal into new loans.

Bullet loans pay interest-only monthly and return the full principal on the maturity date. A EUR 10,000 12% bullet loan pays EUR 100 each month for 12 months, then EUR 10,000 in month 12. Real-estate development loans are almost always bullet: the developer lacks cash flow during construction, so principal repays when the property sells. InRento's rental-income loans and Maclear's SME loans are often bullet or partially amortising. The benefit: your full principal compounds until maturity, maximising interest-on-interest; the risk: the entire principal is exposed until the final payment - if the borrower defaults in month 11, you face a larger loss than if the loan had amortised down to EUR 2,000 remaining.

Investors who want maximum compound growth choose bullet loans with monthly interest reinvested via auto-invest. Investors prioritising risk reduction or planning a withdrawal in 18 months choose amortising loans to harvest principal progressively.

Buyback guarantees: mechanics and limits

A buyback guarantee is a contractual promise by the loan originator to repurchase a loan from investors if the borrower is 60+ days late (some platforms use 30 or 90 days as the trigger). The originator credits your account with the outstanding principal plus accrued interest, removing the defaulted loan from your portfolio. Your yield is unaffected as long as the buyback executes.

Buyback guarantees are prevalent on platforms where loans are originated by third-party finance companies. Robocash, PeerBerry, and Nectaro all offer buyback-backed loans. The mechanism works as follows: Day 1-30 overdue, the platform sends reminders; Day 31-60, arrears status, collections begin; Day 60, buyback triggers, originator repays investors. On Robocash, over EUR 200 million in buybacks have been honoured since 2017 without interruption.

What buyback does NOT cover

Buyback is not deposit insurance. It protects against borrower default but depends entirely on the originator's solvency. If the originator becomes insolvent - as happened with several originators on EstateGuru and Mintos during 2020-2023 - the buyback obligation becomes worthless. Investor compensation schemes like MiFID II cover platform insolvency (up to EUR 20,000 on Mintos and Nectaro), but explicitly exclude borrower defaults. You cannot claim compensation for a loan that defaulted if the platform is still operating.

Platforms with 100% single-originator concentration - where every loan comes from the platform's own lending subsidiary - present extreme buyback risk. If that originator fails, your entire portfolio becomes uncollectible. Lendermarket sources 98% of loans from Creditstar, its parent group; if Creditstar restructures or enters insolvency, the buyback mechanism collapses. Compare this to Mintos, where loans are spread across 60+ originators: one originator's failure affects only that slice of your portfolio.

Reading a loan listing: key fields and what they reveal

When you open a loan listing on a platform, you see a structured data card. Here is how to parse the critical fields:

Loan amount and purpose: EUR 5,000 for "debt consolidation" vs EUR 50,000 for "warehouse expansion" tells you borrower type and risk profile. Small unsecured consumer loans default at 3-8% annually; secured SME loans default at 1-3%. Invoice financing and equipment leasing are the lowest-risk categories; working capital and refinancing are higher-risk.

Interest rate: Compare to the platform average for that loan type. A 16% consumer loan on a platform where the median is 12% suggests a lower credit grade. On secured loans, higher rates often correlate with higher LTV - a 12% rate at 75% LTV is riskier than 10% at 50% LTV.

Term and repayment schedule: 12 months amortising vs 24 months bullet. Check the repayment calendar if provided: some platforms show each instalment amount and date. Front-loaded interest (where month 1 interest is disproportionately high) can indicate a risky borrower paying a premium for fast cash.

Collateral and LTV (secured loans only): "First-lien mortgage on commercial property, appraised EUR 120,000, loan EUR 70,000, LTV 58%." The first-lien position means you are first in line if the property is sold; second-lien loans recover only after the first-lien holder is paid in full. Check the appraisal date - a valuation from 2021 is stale in a 2026 market. LTV below 65% is considered conservative; above 80% is aggressive.

Originator name and rating: Platforms like Mintos assign each originator a risk rating (A+ to C) based on financials, track record, and loan performance. A single-originator platform does not show this field. Cross-reference the originator's name with independent databases or company registries to verify it is a licensed lender.

Buyback status: "Buyback guarantee: Yes, 60 days." Loans without buyback guarantees but with collateral rely on liquidation proceeds for recovery. Unsecured loans without buyback guarantees are the highest-risk category - avoid unless you are buying a diversified pool at a steep discount on the secondary market.

Borrower credit grade (if disclosed): Some platforms show an internal grade (A-E, 1-10, or a proprietary score). Higher grades correlate with lower default rates but also lower yields. A platform that discloses borrower default probability (e.g. "estimated 2.4% annual default rate for this grade") enables precise risk-adjusted return calculations.

What happens when a borrower stops paying: the default cascade

The journey from missed payment to final recovery follows a standard cascade, though timelines vary by platform and jurisdiction.

Days 1-15: Grace period and reminders. The borrower receives automated reminders via SMS and email. No penalty is recorded on the platform yet. If payment arrives by day 15, the loan resumes normally.

Days 16-30: Overdue status. The loan is marked overdue in your portfolio. The platform or originator begins phone contact. A late fee - typically 0.05-0.1% of principal per day, capped at 5% - may be charged to the borrower and passed to investors if collected. You continue accruing interest at the contractual rate during this period.

Days 31-60: Arrears and collection. The loan enters arrears. The originator's collection team escalates: formal demand letters, negotiation of a rescheduling agreement, threats of legal action or collateral seizure. If the loan has a buyback guarantee, the countdown to buyback trigger begins. You still accrue interest, but the probability of full recovery is declining.

Day 60+: Buyback trigger or default declaration. If a buyback guarantee applies, the originator repurchases the loan on day 60 (or 30/90, depending on terms). Your account is credited with outstanding principal plus accrued interest; the loan disappears from your portfolio. If no buyback, the loan is classified as defaulted. Interest accrual stops (or continues at a penalty rate, depending on platform rules), and the loan enters the recovery process.

Months 3-36: Recovery phase (non-buyback defaults). Secured loans proceed to collateral liquidation: the platform or a third-party servicer obtains a court order, appraises the asset, and sells it at auction or via a broker. Proceeds minus legal costs are distributed to investors pro-rata. Unsecured loans are sold to debt collection agencies at 5-15 cents on the euro, or the platform pursues collection in-house. Recovery on unsecured defaults averages 10-30% over 18-36 months. Platforms like Maclear, which hold physical collateral, achieve 70-90% recovery rates on secured defaults within 12 months.

How late fees and recovery proceeds reach your account

When a borrower pays late fees or a defaulted loan is recovered, platforms handle distribution differently. Mintos credits late fees to your account the month they are collected; Maclear distributes recovery proceeds within 30 days of collateral sale. Some platforms deduct a recovery fee (5-15% of recovered amount) to cover legal and auction costs; others absorb these costs in the platform fee.

Check your platform's terms: "Recovery proceeds are distributed quarterly" means you may wait six months after a collateral sale to see funds. Real-time recovery crediting - where each collected payment hits your account within days - is rare but improves cash-flow predictability.

Loan liquidity: secondary markets and early exits

Most P2P loans are illiquid during their term - you hold until maturity unless the platform offers a secondary market. Mintos, PeerBerry (launching 2026), and Twino operate secondary markets where you can list loans for sale before maturity. Buyers pay a price you set: at par (100% of outstanding principal), at a premium (102-105% for high-yield loans in demand), or at a discount (90-95% if you need liquidity fast).

Secondary-market liquidity varies by loan type. High-yield short-term loans with buyback guarantees sell within hours at 99-100% of par. Long-term secured loans or defaulted loans without buyback may sit for weeks and require 10-20% discounts to attract buyers. Platforms like InRento do not offer secondary markets - you hold the full loan term or must find a private buyer outside the platform, which is impractical.

If liquidity is a priority, choose platforms with active secondary markets and short loan terms. If you can commit capital for 24-36 months, illiquid loans often pay 1-2 percentage points more to compensate for the lock-up.
