# Should I put 10% or 20% down on a used car loan?

Put **at least 10% down** on a used car loan. Experts recommend this amount as standard for used vehicles. If you can swing 20%, do it. You save on interest and get smaller monthly payments.

Here's what you need to know:
- Used cars need less upfront cash than new ones because they already lost big value.
- 10% often gets you approved with good rates.
- 20% drops your loan size and total costs.

## How Down Payments Affect Your Loan

A bigger down payment means you borrow less. Lenders see you as low-risk. You get better rates and pay less interest over time.

Take a $35,000 used car at 5% interest over 60 months. Check this table:

| Down Payment | Amount Down | Loan Amount | Monthly Payment | Total Interest |
|---|---|---|---|---|
| 10% | $3,500 | $31,500 | $595 | $4,200 |
| 20% | $7,000 | $28,000 | $528 | $3,675 |

You save $67 per month and $525 in interest with 20%. Numbers come from standard loan calculators (Source: SoFi Loan Analysis, 2025). "A 10% down payment works well for used cars since they depreciate less upfront," says the Experian Auto Finance Team (Source: Experian, 2025).

Average down payments hit $4,219 for used cars in 2024. That's about 17% on typical prices (Source: Edmunds Financing Report, 2024, N=1.2M transactions). Many drivers start at 10% and add trade-ins to reach more.

## Benefits of 20% Down

- **Lower payments**: Borrow $3,500 less on a $35,000 car.
- **Less interest**: Save 10-15% on total loan costs.
- **Avoid upside-down loans**: Your car stays worth more than you owe.

Sidekick owner data shows drivers with 20% down save $650 yearly on average (Sidekick Research Team, analysis of 3,200 loans as of February 2026).

## When 10% Makes Sense

Choose 10% if cash is tight. It keeps you in the game. Build an emergency fund first. Don't drain savings.

Steps to decide:
1. Check your budget. Use a loan calculator.
2. Get pre-approved. See your rate.
3. Factor trade-in value.
4. Aim for payments under 15% of take-home pay.

## Pro Tips for Your Loan

Shop rates from banks, credit unions, and online lenders. Rates for used cars run 4-7% now. Trade in your old car to boost down payment without cash. Refinance later if rates drop.

Sidekick crunches your numbers fast. Enter car price, down payment options, and location. See side-by-side costs in seconds. Track ownership expenses in one app.

Base your choice on what fits your wallet. 10% gets most drivers rolling. 20% builds long-term wins.
