Teen First Car Savings Calculator
Work out the monthly savings a teen needs to buy their first car by a target date, including any interest earned.
How it works
Monthly = (price − saved × (1+r)^n) ÷ ((1+r)^n − 1) ÷ r · r = APY ÷ 12 · n = months
Buying a first car in cash avoids interest costs entirely, so the plan is simply to save the gap between the price and what is already banked, spread over the months available. Money kept in a high-yield savings account earns a little interest along the way, which trims the monthly amount slightly. Budget a cushion above the sticker price for tax, registration, insurance and inevitable early repairs.
Worked example
For an $8,000 car in 18 months with $1,000 already saved at 3% APY: the $1,000 grows a little, so about $383 a month closes the gap, of which interest covers a small share.
Frequently asked questions
Should a teen save up or take a car loan?
Saving and paying cash avoids interest and the risk of owing more than the car is worth. If a loan is unavoidable, a larger down payment and short term keep the interest cost down. Paying cash is almost always cheaper overall.
What extra costs come with a first car?
Beyond the price, budget for sales tax, title and registration, insurance (often high for young drivers), fuel, and a repair fund. A common rule is to set aside an extra 10–20% of the price for these.
Where should the savings sit?
A high-yield savings account or money-market account keeps the money safe and liquid while earning some interest. For a short horizon like this, avoid the stock market, where a downturn could hit right before the purchase.
