The average new car costs about $48,000. A used car in good condition typically runs $25,000-$35,000. Here’s how long it takes to save for either.

Saving a 20% Down Payment to Finance the Rest
Most financial experts recommend at least 20% down on a car to avoid being underwater on the loan.
| Car Price | 20% Down | Monthly $300 | Monthly $500 | Monthly $800 |
|---|---|---|---|---|
| $20,000 | $4,000 | 13 months | 8 months | 5 months |
| $25,000 | $5,000 | 17 months | 10 months | 6 months |
| $30,000 | $6,000 | 20 months | 12 months | 8 months |
| $35,000 | $7,000 | 23 months | 14 months | 9 months |
| $40,000 | $8,000 | 27 months | 16 months | 10 months |
| $50,000 | $10,000 | 33 months | 20 months | 13 months |
Total Cost of Financing vs. Paying Cash
Financing a $30,000 car at different rates vs. paying cash:
| Scenario | Price | Total Paid | Interest Cost |
|---|---|---|---|
| Pay cash | $30,000 | $30,000 | $0 |
| Finance 48 mo @ 5% | $30,000 | $33,145 | $3,145 |
| Finance 60 mo @ 7% | $30,000 | $35,640 | $5,640 |
| Finance 72 mo @ 9% | $30,000 | $38,448 | $8,448 |
Paying cash saves $3,000-$8,000+ compared to financing over 4-6 years.
How Long to Save by Annual Income
Assumes saving 10% of gross income toward a car.
| Annual Income | Monthly Savings (10%) | Time to $6,000 (20% down on $30K) | Time to $30,000 (cash) |
|---|---|---|---|
| $40,000 | $333 | 18 months | 7.5 years |
| $50,000 | $417 | 14 months | 6 years |
| $60,000 | $500 | 12 months | 5 years |
| $75,000 | $625 | 10 months | 4 years |
| $100,000 | $833 | 7 months | 3 years |
The 15% Rule for Car Payments
A sustainable car payment rule: keep total car expenses under 15-20% of monthly take-home pay.
| Monthly Take-Home | Max Car Budget (15%) | Car Value (financing 60 mo @ 7%) |
|---|---|---|
| $3,000 | $450 | ~$22,000 |
| $3,500 | $525 | ~$26,000 |
| $4,000 | $600 | ~$30,000 |
| $5,000 | $750 | ~$37,500 |
| $6,000 | $900 | ~$45,000 |
| $7,000 | $1,050 | ~$52,000 |
Car value includes insurance, which averages $150-300/month.
Practical Strategy
- Target used cars 2-4 years old. You avoid the steepest depreciation (new cars lose 20% in year 1) while still getting a reliable vehicle.
- Save a minimum of 20% down before walking into a dealership. It keeps monthly payments lower and prevents you from being underwater.
- Shop financing before you shop cars. Credit union and online lender rates are often 2-3% lower than dealer financing.
- Use a HYSA while saving. Earning 4-5% on your car savings adds up — $500/month saved for 12 months at 4.5% earns ~$135 extra.
