How this works in your browser
The calculation steps forward month by month, adding your contribution and applying growth to the running balance, until the target is reached. Iterating rather than solving algebraically is what allows both contributions and compounding to be handled together, since each month's growth applies to a balance that the previous month's contribution has already increased. Setting the return to zero collapses it to simple division, which is the honest model for a goal within a couple of years where investment growth should not be assumed at all. Everything is computed in your browser with nothing transmitted.

Frequently asked questions
Does this account for investment growth, not just contributions?
Yes, if you enter an expected annual return, the projection compounds monthly in addition to your regular contributions.
What if I only want to count contributions, no growth?
Set the expected annual return to 0% to see a simple contributions-only timeline.
Is this financial advice?
No, this is an educational estimate only, assuming a constant rate of return which real investments do not guarantee.
Should I invest money I need within a few years?
Generally not, and this is where a growth rate can mislead. Over a short horizon markets can easily be down when you need the money, and there is no time to recover. For a goal within roughly five years, a savings account with a modest guaranteed rate is usually the sounder choice, even though the projection looks less impressive.
Why does a small increase in contributions shorten the timeline so much?
Because contributions do the heavy lifting early on, when the balance is too small for growth to contribute much. In the first years almost all progress comes from what you put in, which is why raising the monthly amount moves the date more than raising the assumed return does.
What if I miss some months?
The timeline extends, and the effect compounds slightly because the missed contribution also never grows. Rather than treating the projection as a commitment, it is more useful as a sensitivity check: run it at a lower monthly figure you know you can sustain.
Are my figures sent anywhere?
No. The calculation runs in your browser, so your goal, balance and contribution stay on your device.
