Estimate payments, total interest, and savings from debt consolidation — with realistic fees and early payoff planning.
A personal loan is an unsecured, fixed-rate installment loan — you receive a lump sum and repay in equal monthly payments over a set term.
Typical Terms (2025)**:
- Amount**: $1,000 – $50,000
- Term**: 12–84 months (36 most common)
- APR**: 6% (excellent credit) to 36% (fair/poor)
- Fees**: 1–8% origination fee (deducted from disbursement)
Example: $15,000 loan @ 12% APR, 36 months: • Monthly payment: **$502** • Total interest: **$3,072** • + 4.5% fee ($675) → **Effective APR = 13.4%**, total cost = **$18,747**
⚠️ Watch for these risky features:
- Precomputed interest (Rule of 78s)** — front-loads interest → no savings for early payoff.
- Prepayment penalties** — rare, but some lenders charge 1–5% for early payoff.
- Balloon payments** — small payments for years, then huge lump sum due.
- Teaser rates** — low intro APR, then jumps (e.g., 5% → 25% after 6 mos).
✅ Always ask**:
- “Is this a simple interest loan?”
- “Are there prepayment penalties?”
- “Is the stated rate APR (includes fees) or interest rate only?”
✅ Good for consolidation** if:
- New APR < weighted avg. of old debts
- Term ≤ longest existing debt
- Origination fee < interest savings
❌ Avoid if**:
- Extending 2-yr debt to 5 years → lower payment, higher interest
- Fee > 5% and savings < 12 months
- Using loan to fund new spending (debt spiral risk)
📊 Case Study**:
- Credit card: $6,000 @ 19.99% → $1,199/yr interest
- Auto loan: $4,000 @ 8.5% → $340/yr interest
- Personal loan: $10,000 @ 12% (36 mo) → $1,932 total interest
- → **Save $607** vs. paying separately
