Key insights

Cars depreciate ~20% year 1, ~50% by year 5

A new $40K car is worth ~$20K after 5 years. If you took a 72+ month loan, you'll be underwater (owe more than the car is worth) for years. Hard to sell, expensive to total.

The 20/4/10 rule

Industry guideline: 20% down + 4-year max loan + total transportation cost under 10% of monthly income. Following all three keeps you out of car-loan trouble.

Pre-approval gives you negotiation power

Get pre-approved at your credit union or bank BEFORE going to the dealer. Their financing department often pads the rate by 1-2 points to capture extra profit.

Recommended actions(4)

Shop financing at your bank/credit union FIRST

High priority

Credit unions typically beat dealer rates by 1-2 points. Get pre-approved before stepping on the lot — gives you walk-away leverage.

Impact: A 2-point rate reduction on a typical $30K, 60-month loan saves ~$1,700 in total interest.

Put at least 20% down on a new car (10% on used)

High priority

Avoids immediate underwater status. If you can't afford 20% down, you can't afford that car — buy cheaper.

Impact: A $40K car with 20% down + 48-month loan has you positive equity within 18 months instead of 4+ years.

Decline most dealer add-ons

Medium priority

Extended warranties, paint protection, fabric protection, GAP insurance all have 50-70% markups. Buy GAP through your own insurer if you need it; skip the rest.

Impact: Typical dealer add-on package: $2,000-4,000. Most of that is profit.
