How much will $50 a month be worth in 5 years?

Investing $50 a month for 5 years means paying in $3,000 in total. At a hypothetical 7% annual return it would grow to $3,560: $3,000 from your contributions and $560 from investment growth. At 4% the balance would be $3,309 ($309 of growth), and at 10% it would be $3,828 ($828 of growth).

4%, 7% and 10% are example rates, not forecasts. Real returns change from year to year and are never guaranteed, and these figures leave out fees, taxes and inflation.

11%	$3,922	$3,000	$922
12%	$4,017	$3,000	$1,017

Assumes no starting balance, a contribution at the end of every month, and a constant rate compounded once a year (an effective annual rate). You pay in $3,000 in every row; only the growth changes, from $75 at 1% to $1,017 at 12%.

How much is your money and how much is growth?

At 7%, 5 years is not long enough for growth to overtake what you pay in: growth is 16% of the final balance and the other 84% is your own money. Keep contributing at the same pace and growth would pass contributions during year 19. A different rate moves that point, but not into these 5 years: it would come in year 14 at 10% and in year 33 at 4%.

In year 5 alone, the balance earns $211 at 7%. That is less than the $600 you add that year, and compares with $19 of growth in year 1.

What if you change the plan?

Each row changes one thing and keeps everything else the same, at the 7% example rate. The comparison is with $50 a month for 5 years, which ends at $3,560.

Change	Final balance	Difference
Keep contributing for 5 more years (10 years in total)	$8,553	+$4,993
Contribute $100 a month instead of $50	$7,120	+$3,560
Start with $10,000 already invested	$17,585	+$14,026
Contribute at the start of each month instead of the end	$3,580	+$20
Earn 6% a year instead of 7%	$3,474	−$86

Another 5 years adds $3,000 of your own money and raises the balance by $4,993. The extra $1,993 is growth, most of it earned on money that was already invested. A return that is one point lower leaves you with $86 less after 5 years, which is roughly what a 1% annual fee would cost.

Working backwards: to reach $5,000 in 5 years at 7%, starting from zero, you would need to invest about $70 a month.

When would the balance reach $5,000?

The table shows the year in which the balance first reaches each amount, assuming the same $50 a month continues for as long as it takes. Years in bold fall within this page's 5-year period.

Balance reaches	At 4%	At 7%	At 10%
$1,000	Year 2	Year 2	Year 2
$2,500	Year 4	Year 4	Year 4
$5,000	Year 8	Year 7	Year 7

How this is calculated

The rate is treated as an effective annual rate, so the balance grows by exactly 7% over a full year. The monthly rate that compounds to 7% a year is:

Monthly rate = (1 + 0.07)^1/12 − 1 = 0.5654%

With $50 added at the end of each month for 60 months (5 × 12), the contributions grow to:

Balance = 50 × [1.005654⁶⁰ − 1] ÷ 0.005654 ≈ $3,560

The rates shown here are rounded; the result uses full precision. Of that balance, 50 × 60 = $3,000 is your contributions and the remaining $560 is growth. Every other row in the rate table uses the same formula with a different annual rate. The compound interest calculator page explains the formulas in more detail.

Frequently asked questions

How much interest will $50 a month earn in 5 years?

It depends on the rate of return. At a constant 7% a year, $50 a month for 5 years earns $560 on top of $3,000 in contributions, for a balance of $3,560. At 4% the growth is $309, and at 10% it is $828. These rates are examples, not predictions.

How long does it take to reach $5,000 investing $50 a month?

With a constant 7% annual return and no starting balance, the balance passes $5,000 during year 7. For comparison, at 10% it takes until year 7, and at 4% it takes until year 8.

How much do I need to invest each month to have $5,000 in 5 years?

At a constant 7% annual return you would need about $70 a month for 5 years, starting from zero. At 4% you would need about $76 a month, and at 10% about $65 a month.
