ETF & index fund data, made ridiculously simple

Pick one index fund. See how bumpy it really is day to day, what $10,000 would have done, and whether investing all at once or bit by bit worked better. Plain words, real data, no jargon.

Daily movement

How many days of the year moved 1% or more? Big up days, big down days, calm days, best and worst day — the whole year at a glance.

Monthly returns

You invest $10,000 at the start of a year. Follow your balance month after month, in dollars and percent, through calm and rollercoaster months.

Lump sum vs DCA

Every year side by side: how $10,000 performed as a lump sum vs dollar-cost averaging, and which strategy won each year.

Compare ETFs

Pick two funds and let them fight it out — yearly returns side by side, one winner per year. Value vs growth, S&P vs Nasdaq, any matchup you like.

Pie calculator

Slice your own pie out of the tracked ETFs, add a starting sum and monthly or weekly buys, and see what it would have grown into over the years.

How much should I invest?

Type in what you earn and what you spend each month, and get a recommended monthly investment — plus what that habit would have grown into.

Same index, three markets

Most of these funds also exist as a US listing, a Xetra EUR line and a London GBP line. Find every version of every index in one table.
