Banks vs credit unions vs online lenders: where to borrow
The cheapest personal loan for your specific profile comes from a credit union about half the time, an online lender about 40% of the time, and a traditional bank about 10% of the time. Here's how to figure out which one fits before you spend hard inquiries finding out the hard way.
Banks (the conservative option)
Big national banks (Wells Fargo, US Bank, Discover, Citi) offer personal loans typically at the lowest APRs in the market but with the strictest underwriting. Approvals usually require FICO 660+, multi-year banking relationship, and clean recent credit.
APR range: 7% to 24% typical, with the lower end reserved for existing customers with substantial assets.
Loan amounts: $3,000 to $100,000 (higher than most online lenders).
Funding: 1-5 business days after approval. Slower than online lenders but faster than HELOCs.
Who they fit: existing bank customers with good credit who want predictability and full in-person service. New customers and thin-file borrowers usually face declines.
Credit unions (the often-overlooked best deal)
Credit unions are member-owned non-profits regulated under federal or state credit-union charters. Their personal-loan APRs frequently beat banks AND online lenders for borrowers who qualify for membership.
APR range: 6% to 18% typical for personal loans. Even for fair-credit members, APRs often run 5-10 percentage points below comparable bank or online offers.
Loan amounts: $500 to $50,000.
Funding: 1-3 business days.
Membership: many credit unions have broad fields of membership (geographic, employer-based, or community-based). Some accept anyone willing to join an associated organisation for a small fee. Navy Federal, PenFed, and Alliant are large credit unions with wide membership eligibility.
Who they fit: anyone willing to spend 30 minutes joining. The rate savings on a multi-year loan typically pay back the membership effort hundreds of times over.
Online lenders (speed and credit-tier flexibility)
Online installment lenders (SoFi, LightStream, Marcus, Upgrade, Best Egg, LendingClub, Upstart, Avant) dominate the personal-loan market by volume. They differentiate on speed, credit-tier flexibility, and alternative-data underwriting.
APR range: 6% to 35.99%. The wide range reflects the wide credit-tier range they serve. Prime lenders like SoFi and LightStream serve 700+ FICO at single-digit APRs; subprime lenders like Avant and OneMain Financial serve 580+ FICO at 25-35% APRs.
Loan amounts: $1,000 to $50,000 typical, up to $100,000 at some prime lenders.
Funding: same day to next business day. Fastest in the market.
Who they fit: nearly everyone. Fair-credit borrowers especially because banks and many credit unions decline them. Speed-sensitive borrowers because online funding is the fastest available.
The right shopping sequence
Step 1: pre-qualify with 3-5 online lenders through a marketplace. Soft credit pull, doesn't affect score. Captures most of the market in 5-10 minutes.
Step 2: get a quote from one or two credit unions (especially Navy Federal if you have any military connection, Alliant for anyone, your local credit union if you have one). Soft pulls available on request.
Step 3: if you're an existing customer at a big bank, get their quote too. They sometimes match competitor offers when you bring documentation.
Step 4: compare effective APR (rate plus origination fee, the disclosed APR under TILA). Pick the lowest effective APR with terms you understand.
Don't skip the credit-union step even if it feels slow. Their rates are frequently the lowest available; the 30-minute membership step pays for itself many times over.
Quick answers.
Are credit unions really cheaper than online lenders?+
For fair and good credit (620-740 FICO), credit unions are cheaper about 60% of the time. For excellent credit (740+), online prime lenders like SoFi and LightStream are competitive or cheaper. For subprime credit (below 620), credit unions sometimes decline; online subprime lenders are usually the only realistic option.
Can I get a personal loan from my bank without being a customer?+
Generally no for big national banks. Some smaller banks accept new applicants but the rates are usually worse than what an existing customer would see. If you're going to apply to a bank, become a customer first; even a savings account opened a few months earlier helps.
Do credit unions check credit?+
Yes. The 'community lender' branding can suggest they don't, but they do. They're often more willing to factor in non-credit data (membership history, banking relationship, employer) alongside credit, which helps borderline applicants.
How do I find a credit union I can join?+
Federal credit unions you can join from anywhere: PenFed, Alliant Credit Union, Navy Federal (military-affiliated or working at certain federal agencies). For community credit unions, NCUA.gov has a credit-union locator. Many state credit unions accept anyone living or working in the state.
