Retirement Savings Goal Monthly Deposit Calculator (10 Years)

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

The Monthly deposit figure is the fixed amount to set aside every month over 10 years, with interest assumed at the entered rate, so that the deposits plus growth reach the goal amount by the end of the term.

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 amount $50,000, annual rate 5%, term 10 years. The monthly rate is 5% divided by 12, which is about 0.4167% a month, and the number of deposits is 10 times 12, which is 120 months. Using the page formula, the monthly deposit is $50,000 times the monthly rate, divided by one plus the monthly rate to the power of 120, minus one, which gives $321.99 a month. That is the calculator output for these defaults. On an unrounded basis, total deposits over 120 months are $38,639.31, so growth adds $50,000 minus $38,639.31, which is $11,360.69, toward the goal. Without interest, the same goal would need $50,000 divided by 120, which is $416.67 a month, so interest saves about $94.67 a month on an unrounded basis.

Who this term suits for a retirement saver: A worker in their fifties building a retirement supplement over the next decade, for example adding to a pension pot that will cover everyday spending once regular pay stops, without relying on one lump sum at the end.

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 retirement 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.

Is $321.99 a month realistic for a 10-year retirement goal?
For many workers it is: $321.99 a month for 120 months, with total deposits of $38,639.31 and growth of $11,360.69. It is less than half the 5-year deposit, because ten years gives interest more time to work.

What does the $11,360.69 of growth actually mean here?
It is the part of the $50,000 goal you do not pay yourself: your deposits total $38,639.31 and interest adds the remaining $11,360.69. Without interest you would need $416.67 a month instead of $321.99.

Should I raise the deposit as retirement gets closer?
Raising it when pay rises is sensible, because the goal itself may need revisiting: a $50,000 pot set today may buy less in ten years, and a higher deposit protects against that drift.
