FAQ
What is a ladder buy?
Instead of buying everything at once, you split the order into several tranches. If the price keeps falling you buy lower and pull your average down; if it rises, the shares you already own gain. It softens the damage of getting the timing wrong.
How many tranches should I use?
There is no single answer, but three to five is the common range. More tranches smooth the average further, yet each order gets smaller — fees weigh more and the plan gets harder to follow to the end.
Equal or pyramid?
Equal weighting puts the same amount into every tranche: simple and predictable. A pyramid puts more in as the price falls, pulling the average down harder — but the loss grows with it if the decline continues. Switch between them and compare.
How is the running average calculated?
It is the weighted average: everything actually spent up to that tranche divided by the total quantity. Whole shares are rounded down, so leftover cash is shown separately. Turn on fractional quantities for crypto or fractional-share accounts.
How is this different from the averaging-down calculator?
The averaging-down calculator answers “if I buy more now, what does my average become?” after you already own shares. This one is for before you buy: where and how much to buy. Plan here, then manage the position there.
