Investment Future Value Monthly Savings Calculator (5 Years)

Estimate the future value of regular monthly savings. This investment version uses a 5-year planning term as its starting point.

What this means: the Future value is the total amount built up from the regular monthly deposits plus the growth earned on them over the full 5-year term, so a larger monthly deposit, a higher rate, or a longer term will raise this final amount.

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 5 years. The monthly rate is 6% divided by 12, which is 0.5% a month, and the number of deposits is 5 times 12, which is 60 months. Using the page formula, the future value is $500 times one plus 0.005 to the power of 60, minus one, divided by 0.005, which gives $34,885.02. That is the calculator's own output for these defaults.

The deposits actually paid in total $30,000, so interest is $34,885.02 minus $30,000, which is $4,885.02. That interest is only an estimate: the 6% rate is the entered assumption, and a lower real average return would leave the same deposit short of this figure.

Who this term suits for an investor: an investor building a near-term lump sum for a planned investment, such as a top-up for a first rental-property deposit, a stake in a small business, or a portfolio position due in about 5 years, where the deposit is high enough to matter but interest has little time to help.

FAQs

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

Is this investment 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.

Can an investor really afford $500 a month for 5 years?
Only if the $500 is spare after essentials, emergency savings and any expensive debt are covered; $500 a month for 5 years is $30,000 of deposits, so a missed year still leaves most of the plan intact, but the growth of only $4,885.02 shows that 5 years gives compounding little time to work.

Why does interest add only $4,885.02 over 5 years?
Because most deposits are made late in the term and earn interest for only a short time; the first $500 earns interest for 60 months, but the last $500 earns it for barely one month, so early deposits do most of the work and a short term limits the total.

What if the market return falls below 6% during the 5 years?
The final figure falls below $34,885.02, and the shortfall is larger than many investors expect, because a lower rate affects every deposit at once; an investor should check the plan at a lower rate, such as 3%, before committing the $500 a month.
