What would a fixed weekly amount have done over the last two years? Run it yourself, beside plain scheduled spending of the same money, and see why the comparison that matters is cost per unit and not the final number.
Pick a set of rules, a pair and a window. The left column is the rules you picked. The right column is plain scheduled spending of the same total. It is always shown, because without it every rule looks like it worked.
A simulation of the past, not a forecast. Fees are modelled at 0.1%; slippage, exchange minimums and taxes are not. Past prices do not predict future results.
Putting the same amount into an asset at a fixed interval, whatever the price is that day. When the price is low the amount gets you more units; when it is high, fewer. Your average cost ends up somewhere inside the range of prices you paid.
It is not a way to come out ahead. Decades of research on shares, and the same arithmetic on crypto, say that putting a lump sum in at once has finished ahead of spreading it out more often than not, simply because the money was exposed for longer. Averaging in does not fix that, and nothing on this page says it does.
Most people do not have a lump sum. They have part of a monthly income. A fixed schedule removes the question of when, which is the question that makes people freeze, chase a rally or sell a fall. Its value is behavioural: it is a plan people actually keep.
Averaging into something that keeps falling and never recovers just averages a loss. A schedule does not make an asset safe. Crypto prices have fallen by more than half, more than once, and may not come back. Only ever use money you can afford to lose entirely.
In a window where the price rose, any rule that spent its money earlier finishes with a bigger number, whether or not the rule is any good. That is why the replay always runs plain scheduled buying beside it with the same total spent, and compares cost per unit instead.
Six months, twelve and twenty-four can tell three different stories about the same plan. Run all three. If a rule only looks good in one of them, you have learned about that window, not about the rule.
A replay answers one question: what would these rules have done over prices that already happened? It cannot see the next twelve months, and neither can anyone selling you a number.
Unfamiliar word? The glossary defines the terms used here in plain language.
No. This page explains a method and lets you replay it over past prices. It does not tell you to buy, sell or hold anything, and it does not know your circumstances. Speak to a qualified adviser before making investment decisions.
Daily closing prices for the last 24 months, from a public exchange price feed. The replay models a 0.1% fee. It does not model slippage, exchange minimum order sizes or taxes.
That is the history we can serve reliably. Stating a longer horizon than we can actually cover would make the answer worse, not better.
No. It runs on this page, with no account and no payment details.
