Your credit policy is the foundation of a profitable personal loan business—get it right and you filter out risk while winning quality borrowers. A weak policy leaves you exposed to defaults; a rigid one kills your pipeline. Here's how to build one that actually works.
Why Credit Policy Matters for Your Bottom Line
Most lenders jump straight to FICO scores and debt-to-income ratios without asking what matters for your book of business. A generic 680 minimum credit score might work for a competitor, but it could be wrong for you depending on your loan sizes, geography, and risk appetite.
Your credit policy determines approval rates, default rates, and ultimately your profitability. Tighter policies reduce losses but shrink your addressable market. Looser policies grow volume but spike chargeoffs. The goal is finding your sweet spot.
Core Components of a Defensible Credit Policy
Credit Score Ranges
Set minimum and preferred tiers. Most personal loan lenders operate in these bands:
- Prime (740+): Typically 3–5% default rates; can price at 8–12% APR
- Near-Prime (660–739): 8–12% default rates; price at 14–22% APR
- Subprime (580–659): 15–25% default rates; price at 24–36% APR
Your minimum floor protects you. Going below 580 creates compliance risk (FCRA, state lending laws) and operational headaches. Starting at 640 as a minimum gives you room to grow into riskier segments later without bleeding money.
Debt-to-Income Thresholds
Calculate gross monthly debt payments divided by gross monthly income. Most lenders cap this at 40–50% for personal loans.
- If a borrower earns $4,000/month and carries $1,500 in debt payments, their DTI is 37.5%—approvable at 45% max.
- At 50% DTI, you're relying heavily on their commitment to repay rather than capacity. That works for strong credit profiles; it's riskier for subprime.
Income Verification Requirements
Decide what counts as proof. Common standards:
- Recent pay stubs (2–3 months)
- Tax returns (1–2 years, for self-employed)
- Bank statements (60 days, showing deposits)
- Employment verification letters
Don't skip this. A 720 credit score borrower who overstates income is still a bad loan. Verify at least 80% of applications above $10,000.
Loan Size Caps by Credit Tier
Align maximum loan amounts to risk. Example framework:
- Prime borrowers: $25,000–$50,000
- Near-Prime: $10,000–$25,000
- Subprime: $5,000–$10,000
This prevents a single default from tanking your month. It also makes servicing and collections easier at lower balances.
Trade Line and Account History Checks
Look beyond the score. Review:
- Oldest active account age (ideally 2+ years)
- Recent delinquencies (anything 30+ days late in the last 12 months flags risk)
- Mix of credit types (installment + revolving is healthier than revolving only)
- Hard inquiries in the last 90 days (signals multiple recent applications—red flag)
A 700 score with three recent 30-day lates is riskier than a 680 with clean payment history.
Documentation and Compliance
Write your policy down. Regulators and auditors expect consistency. Document:
- Your minimum credit score
- Your DTI limits by loan type
- Income verification methods
- Underwriting exceptions and who can approve them
- How you handle disputes or policy violations
This protects you in default litigation and keeps your team aligned. Update it annually or when market conditions shift.
Pricing to Match Your Risk Profile
Once you've defined credit tiers, price accordingly. Your APR compensates for expected losses.
If your near-prime segment (660–739) has a 10% default rate, you need enough spread in pricing and fees to cover that loss plus operational costs and margin. Many lenders underprice because they misjudge their actual default rates.
Run monthly cohort analysis: track what your borrowers from Q1 actually defaulted at by credit tier. This data shapes next year's policy.
Scale Faster with Better Lead Flow
Listing your personal loan offerings on Mercoly puts you in front of borrowers actively searching for lenders—boosting your qualified leads without expensive ad spend.
Frequently Asked Questions
Q: Should I use credit scores from multiple bureaus? Most lenders pull one bureau (typically Equifax for cost) and use the score provided. Pulling all three is more expensive but catches discrepancies; reserve this for loans above $20,000 or when initial scores are borderline.
Q: How often should I update my credit policy? Review it quarterly against your actual portfolio performance and annually for market changes; adjust if your default rates drift more than 2–3 percentage points from projections.
Q: Can I approve below my minimum score if debt-to-income is exceptional? Yes, but document the exception and the business rationale every time; this prevents policy creep and keeps underwriting defensible.
