Personal Savings Goal Monthly Deposit Calculator (10 Years)

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

The Monthly deposit figure is the regular amount to set aside each month over the full 10 years, at the annual rate entered, in order to reach the goal amount. In practical terms, it turns a large distant target into a fixed monthly habit: paying that amount every month keeps the plan on track, while missed months or a lower rate would leave the total short of the goal.

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 person: A 10-year term suits a person in mid-career saving for a child's school or university fund, or for a house move in the next decade, who expects pay to rise and can start at $321.99 a month. The amount is less than half the 5-year figure, so it fits a household budget more easily, but the goal still needs regular checking as prices change.

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 personal 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 goal is spread over 120 payments instead of 60, and interest has twice as long to work. Total deposits fall to $38,639.31 and interest rises to $11,360.69, which is 22.7% of the goal. The saving compared with 5 years is $413.24 a month, which is why a 10-year plan feels much easier on a household budget.

Should I raise my deposits as my pay rises over 10 years?
Raising deposits when pay rises is a sensible way to reach the goal sooner or to raise the goal, but this calculator shows a fixed $321.99 a month at a fixed 5% rate. If you raise the amount, use the calculator again with the new monthly figure in mind, and remember that the result is an estimate for planning only, not financial advice.

Will $50,000 still buy what I want in 10 years?
Not necessarily, because prices usually rise over 10 years, so $50,000 in 10 years will buy less than $50,000 today. This calculator does not adjust for inflation. If the goal is a house deposit or university costs, check current prices and consider whether the goal itself should rise over the 10 years.
