OneMain Financial vs Prosper

The short version

OneMain Financial and Prosper both make fixed-rate installment loans, but they sit at different ends of the credit spectrum. OneMain doesn’t publish a minimum credit score and weighs your overall credit history and the income you have left after monthly expenses instead, which is part of why it approves some borrowers that banks and top-tier online lenders turn away. Prosper states a firm 640 minimum credit score to qualify, and says applicants under 600 might not qualify at all.

APRs, as of September 2026, run 11.99% to 35.99% at OneMain and 8.99% to 35.99% at Prosper. OneMain’s origination fee varies by state — a flat $25 to $500 or 1% to 10% of the loan — while Prosper’s runs 1% to 9.99% of the loan. Prosper lends up to $50,000 over as long as 72 months, versus OneMain’s $30,000 cap over 60 months, but Prosper’s funding also depends on investor commitments behind its marketplace, which OneMain’s direct-lending model doesn’t share.

Rates and fees

OneMain’s published range is 11.99% to 35.99% APR, and most loans carry an origination fee — either a flat $25 to $500 or 1% to 10% of the loan, depending on your state — deducted before the money reaches you, with no prepayment penalty. Prosper’s published range is 8.99% to 35.99% APR, with an origination fee of 1% to 9.99% of the loan amount deducted from your proceeds; Prosper also charges no prepayment penalty. Prosper’s own pages mention a late fee and an insufficient-funds fee can apply but don’t publish the dollar amounts.

Take a $10,000 loan over 36 months at the midpoint of each lender’s published APR range and fee range, to compare the two on equal footing.

OneMain, 23.99% APR (midpoint of 11.99%-35.99%), using the midpoint of its 1%-10% percentage-fee range (5.5%). OneMain’s fee varies by state and can also be a flat $25 to $500 instead of a percentage; this example uses the percentage midpoint. The fee is $550.00, so you’d receive about $9,450.00 in cash. An APR already includes the origination fee by definition, so we amortize the cash you actually receive at the APR rather than counting the fee a second time: a payment of about $370.70 a month, total payments of about $13,345.20, and a total cost of roughly $3,895.20 over the $9,450.00 you actually received. These are our own amortization figures, not a lender quote.

Prosper, 22.49% APR (midpoint of 8.99%-35.99%), using the midpoint of its 1%-9.99% fee range (5.495%). The fee is $549.50, so you’d receive about $9,450.50 in cash. An APR already includes the origination fee by definition, so we amortize the cash you actually receive at the APR rather than counting the fee a second time: a payment of about $363.32 a month, total payments of about $13,079.52, and a total cost of roughly $3,629.02 over the $9,450.50 you actually received. These are our own amortization figures, not a lender quote.

On this comparison, the two land close together — Prosper’s slightly lower midpoint APR nets a slightly lower total cost than OneMain’s.

Who qualifies

OneMain doesn’t publish a minimum credit score; it says approval depends on your overall credit history and how much income you have left after monthly expenses. Its published requirements are being at least 18 (19 in some states), showing photo ID and proof of residence, and documenting a verifiable source of income, plus an in-person or virtual verification appointment for many applicants.

Prosper states that borrowers must have a credit score of 640 or higher to qualify, and that applicants under 600 might not qualify at all. Beyond credit, Prosper asks for verifiable income, a bank account for direct deposit, and basic identifying information (name, address, date of birth). Checking your rate with either lender starts with a soft credit pull that doesn’t affect your score. On availability, Prosper isn’t offered in Iowa or West Virginia, while OneMain doesn’t originate loans in Alaska, Arkansas, Connecticut, Massachusetts, Rhode Island, Vermont, or Washington, D.C.

Speed and funding

OneMain says money can be available within an hour of closing through its SpeedFunds debit card, or in one to two business days if you’re paid by check or ACH, though getting to closing often means a branch visit first. Prosper says you may receive your funds as soon as one business day after accepting an offer, completing verification, and getting final approval, deposited directly into your bank account — though because funding also depends on investor commitments behind its marketplace, Prosper’s own language is that eligibility “is not guaranteed.”

Where each one wins

• OneMain — no published minimum credit score, and it approves some borrowers that banks and top-tier online lenders turn away.
• OneMain — a secured loan option using a vehicle as collateral, which typically lowers the rate.
• OneMain — more than 1,300 branches for in-person support.
• Prosper — a lower APR floor (8.99% versus OneMain’s 11.99%) as of September 2026.
• Prosper — a higher loan ceiling ($50,000 versus OneMain’s $30,000) and terms up to 72 months.

Bottom line

If your credit sits below Prosper’s 640 floor, or you’d rather not wait on investor-backed funding, OneMain’s no-published-minimum underwriting and branch network make it the one to check first. If your credit clears 640 and you need more than $30,000, Prosper’s higher ceiling and longer terms are worth comparing. Personal-loan credit score requirements is worth reading before you decide which one to try first.
