Staged-buy calculator: instalments and average cost

Buying in stages cannot guarantee a profit. It simply avoids putting the whole budget into one moment. This scenario assumes equal cash amounts and prices spaced evenly between the start and end values you enter.

Use it without fooling yourself

Set the total budget first, then choose time or price triggers. Do not let a falling price turn a capped plan into unlimited buying. Entering a higher final price also shows the average cost of buying into a rise.

Before acting, use the pre-buy checklist and confirm the resulting allocation with the rebalancing calculator.
