What do banks require for a loan? (The 5 main requirements)

Banks and lenders evaluate five core factors before approving a loan: credit score, income and employment, debt-to-income ratio, collateral (for secured loans), and loan purpose. Meeting all five at acceptable thresholds is what gets a loan approved at a competitive rate.

Every bank, credit union, and online lender runs loan applicants through roughly the same five-part checklist. The details vary by lender and loan type, but the underlying framework is consistent — lenders are asking one central question: how likely is this borrower to repay, and under what terms? Here are the five factors they measure.

1. Credit score

Your credit score is typically the first gate. As myFICO explains, 90% of top lenders use FICO scores, which range from 300 to 850. Score bands that most lenders use: 800+ (exceptional), 740–799 (very good), 670–739 (good), 580–669 (fair), below 580 (poor). A higher score unlocks lower rates and better terms. Borrowers below 580 may still qualify — particularly at credit unions or with a co-signer — but rates reflect the added risk. The CFPB notes that lenders use different scoring models for different loan types, so the exact threshold varies.

2. Income and employment

Lenders verify that you have a stable, sufficient income to repay the loan. For employees, that typically means recent pay stubs and W-2s (or tax returns for the prior one to two years). For self-employed borrowers, expect two years of federal tax returns and possibly bank statements. Lenders care about two things: the amount (enough to cover the new payment) and the stability (consistent job history with no unexplained gaps). Most lenders want at least two years of employment history, though requirements vary by loan type.

3. Debt-to-income ratio (DTI)

Your debt-to-income ratio is your total monthly debt payments divided by your gross monthly income. The CFPB defines DTI as one of the key measures lenders use to assess your ability to manage monthly repayments. Most lenders target a DTI below 36–43% — the new loan payment included. Mortgages have stricter rules: qualified mortgages generally require a DTI at or below 43%. Personal and auto lenders vary, but DTI above 50% typically limits options to higher-rate products. Lower DTI signals more breathing room in your budget — and more confidence for the lender.

4. Collateral (for secured loans)

Secured loans — mortgages, auto loans, HELOCs, secured personal loans — require an asset as collateral. The lender places a lien on that asset; if you default, they can seize it to recover what they're owed. Collateral requirements are loan-specific: a mortgage requires the home, an auto loan requires the vehicle, a HELOC requires sufficient home equity. Lenders typically lend against a percentage of the asset's value — the loan-to-value ratio (LTV). Unsecured personal loans require no collateral but compensate with higher rates and stricter credit requirements.

5. Loan purpose and documentation

Some lenders ask how you plan to use the funds, particularly for personal loans — debt consolidation, home improvement, medical expenses, and major purchases are typically accepted purposes. Certain uses (gambling, business purposes on a consumer loan) may be prohibited. Beyond purpose, lenders need to verify your identity: government-issued photo ID, Social Security number, and current address. This is a legal requirement under federal Know Your Customer (KYC) rules, not optional.

What lenders actually do with these five factors

How to strengthen your application before applying

  1. Raise your credit score: Pay down revolving balances to below 30% of your credit limit and dispute any report errors at AnnualCreditReport.gov. Score improvements happen within 30–60 days for utilization changes. See How to Qualify for a Lower Interest Rate.
  2. Lower your DTI: Pay down existing debt or hold off on other new credit before applying. Even eliminating one small installment loan can move your DTI several points.
  3. Document your income thoroughly: Self-employed borrowers should have two years of filed tax returns ready. If you have variable income, average your last two years and be prepared to explain fluctuations.
  4. Use pre-qualification first: Most lenders offer a soft-pull rate check that doesn't affect your score. Compare at least three offers before letting anyone run a hard inquiry. See How to Prequalify for a Loan.
