Car Savings Goal Monthly Deposit Calculator (10 Years)

Find the monthly deposit needed to reach a savings goal. This car version uses a 10-year planning term as its starting point.

The Monthly deposit figure is the fixed amount to save each month over the whole 10 years to reach the goal amount at the rate entered, assuming every monthly deposit is made and the rate stays unchanged.

Formula

Monthly deposit equals goal times monthly rate divided by one plus monthly rate to the power of months minus one.

How it works

Saving a fixed amount each month with interest reaches the goal faster than saving without interest.

Worked example

Goal $50,000, annual rate 5%, term 10 years. First, the monthly rate is 5% divided by 12, which is 0.0041667, and the number of payments is 10 times 12, which is 120. Using the monthly deposit formula, the monthly deposit is $321.99. Over 120 payments the deposits add up to $38,639.31, calculated from the unrounded deposit exactly as the calculator does, and interest adds $11,360.69 to reach the $50,000 goal. That interest is 22.7% of the goal.

Who this term suits for a car buyer: A 10-year term suits a car buyer planning the next car well ahead, for example a family saving for a larger car as children grow, or a driver building a fund for a reliable car to replace a car bought today. Car models and prices will change in 10 years, so the $50,000 goal should be reviewed, not treated as a fixed price.

FAQs

How much should I save each month?
Divide the goal by the growth of regular deposits at the assumed rate to get the monthly amount.

Is this car calculator exact?
No, it is an estimate for planning only, based on the numbers you enter.

Are these figures financial advice?
No, they are estimates for planning only, not financial advice. Check with a qualified adviser for decisions involving large sums.

Why does the 10-year deposit fall to $321.99, less than half the 5-year amount?
Because the buyer gets 120 payments instead of 60, and interest has twice as long to work. On $50,000 at 5%, deposits add up to $38,639.31 and interest adds $11,360.69, so the monthly amount more than halves. The trade-off is time: the car must wait 10 years, and its price may change in that time.

Should I raise my deposits as my pay rises over 10 years?
Raising deposits when pay rises is the safest way to keep a 10-year car plan on track, because it builds a buffer against car-price rises and missed months. This calculator assumes a fixed $321.99 a month, so any increase would reach the goal sooner or allow a larger car fund, but it is not included in the result shown.

Will $50,000 still buy the car I want in 10 years?
Not necessarily. Car prices, models, and fuel types change over 10 years, and $50,000 today may buy a different car in 10 years. The buyer should treat $50,000 as a fund target, not a fixed car price, and review the goal every year or two against current car prices.
