🚗 Car Loan Affordability: How Much Car Can You Afford?
Buying a car is one of the biggest financial decisions you’ll make. Here’s how to calculate what you can afford without hurting your finances.
💰 The 20/4/10 Rule for Buying a Car
Financial experts recommend the 20/4/10 rule to keep your car purchase within a reasonable budget:
- ✅ 20% down payment – Pay at least 20% upfront to reduce the loan size.
- ✅ 4-year loan term (max) – Keep your loan term to 48 months or less to avoid excessive interest.
- ✅ 10% or less of monthly income – Your total car payment (loan + insurance) should not exceed 10% of your take-home pay.
📌 Hidden Costs of Car Ownership
Car loans aren’t the only expense. Make sure you budget for:
- 🚗 Insurance premiums – Higher for newer and financed cars.
- ⛽ Gas and maintenance – Ongoing costs that can add up.
- 🏦 Depreciation – New cars lose value quickly; used cars hold value better.
- 🔧 Repairs – Older cars may need more frequent repairs.
- 🛣️ Registration and taxes – These can vary by state and add to yearly ownership costs.
- 💳 Loan interest – The longer your loan, the more interest you pay.
