Retirement Future Value Monthly Savings Calculator (30 Years)

Estimate the future value of regular monthly savings. This retirement version uses a 30-year planning term as its starting point.

In real terms, the Future value is the total amount you would have at the end of 30 years from your monthly deposits plus the interest they earn, so a higher figure means a larger retirement pot, not extra monthly income on its own.

Formula

Future value uses the monthly rate and the number of monthly deposits to grow each deposit with interest.

How it works

Each monthly deposit earns interest from the month it is made until the end of the term.

Worked example

Monthly deposit $500, annual rate 6%, term 30 years. The monthly rate is 6% divided by 12, which is 0.5% a month, and the number of monthly deposits is 30 times 12, which is 360 deposits. Using the page formula, future value equals $500 times one plus 0.005 to the power of 360, minus one, all divided by 0.005, which is $502,257.52. That is the calculator's own result for these defaults. Total deposits are $500 times 360, which is $180,000, so interest adds $502,257.52 minus $180,000, which is $322,257.52.

Who this term suits for a retirement saver: a young professional starting retirement saving early, with thirty years for a modest monthly habit to grow into a substantial retirement fund, provided the habit is kept up through pay rises, job changes and market falls.

FAQs

How does monthly saving grow?
Regular deposits grow because each deposit earns interest, and that interest then earns more interest.

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.

Why does the 30-year figure pass $500,000?
Because thirty years of compounding turns $180,000 of deposits into $502,257.52, with interest of $322,257.52 doing most of the work. Growth speeds up in later years, since interest is earned on a much larger balance than in the early years.

Should a 30-year retirement figure include tax and fees?
Yes, in a real plan. This page excludes fees, taxes and inflation, so a real fund after thirty years would be lower. The page figure is useful for comparing the power of steady saving, not as a promise of what you will receive.

Can $500 a month fund retirement in 30 years?
It can build a substantial fund, but whether it funds retirement depends on spending in retirement, other pension income and inflation over thirty years. A $500 habit started early is a strong start, and raising it with pay rises makes it far stronger.
