You need $20,000. You could get a personal loan or a line of credit. Both give you access to $20,000. Both have interest charges. But the two products work completely differently — and choosing the wrong one for your situation can cost you real money or create real problems.
Here's what most comparison articles miss: the right choice depends almost entirely on how you plan to use the money, not on which product looks cheaper at first glance. Let's break this down properly.
Core Definitions: How Each Product Works
The structural difference sounds simple. But it creates very different cost profiles depending on how the money is actually used.
Side-by-Side Comparison
| Feature | Term Loan | Line of Credit |
|---|---|---|
| Disbursement | Lump sum upfront | Draw as needed |
| Repayment | Fixed monthly payments | Variable (interest-only or minimum) |
| Interest Calculation | On full principal from day 1 | Only on drawn balance |
| Rate Type | Usually fixed | Often variable |
| Reusability | No — single use | Yes — revolving |
| Typical APR Range | 6%–36% (personal) | 8%–24% (unsecured) |
| Budgeting Predictability | High — same payment every month | Low — payment varies with balance |
| Best For | One-time defined expenses | Ongoing or unpredictable needs |
When to Choose a Term Loan
A term loan is the better choice when you know exactly how much money you need, you need it all at once, and you want predictable repayment. Specific situations where loans win:
- Debt consolidation — you know the total amount, you want one fixed payment, and you want a firm payoff date. See our debt consolidation loan guide for details.
- Home renovations — contractors quote fixed project costs. You borrow the project total, not a revolving fund.
- Medical expenses — known lump-sum costs that you want to pay off systematically.
- Major purchases — car, furniture, one-time equipment purchase.
The fixed payment structure is a feature, not a bug. It forces a specific payoff timeline. For debt consolidation especially, that discipline matters — a revolving line of credit can be re-drawn, undoing all your payoff progress.
When to Choose a Line of Credit
A line of credit makes more sense when your borrowing needs are ongoing, variable, or uncertain in amount. Situations where a LOC wins:
- Business cash flow management — seasonal revenue gaps, payroll timing, opportunistic inventory purchases. A business line of credit is the standard tool for this.
- Home equity line (HELOC) — ongoing home improvement projects where costs unfold over time. Draw only what you need for each phase.
- Emergency fund backup — a personal line of credit used as a buffer. You pay nothing if you don't draw on it (or a small annual fee).
- Freelance or variable income earners — a line lets you bridge income gaps without paying interest on money you don't need yet.
Real Cost Comparison: Same Scenario, Different Product
Say you need $20,000 for a project that will happen over 12 months. You'll draw the money in tranches of roughly $5,000 per quarter. Here's what each product costs:
| Scenario | Term Loan at 10% | Line of Credit at 12% |
|---|---|---|
| Month 1 balance | $20,000 | $5,000 |
| Month 3 balance | ~$18,500 | $10,000 |
| Month 6 balance | ~$16,500 | $15,000 |
| Month 12 balance | ~$12,500 | ~$15,000 (being repaid) |
| Estimated total interest (36 months) | ~$3,200 | ~$2,400 |
The LOC wins here despite its higher rate — because you only borrowed what you needed, when you needed it. Had you needed the full $20,000 immediately, the loan at 10% would have been cheaper than the LOC at 12%.
