Where can I find a arrow tragectory vs speed calculator ?

What I'm trying to do is work out the difference in trajectory on paper before buying different arrow setups .

For example the diffence between an arrow weight of 478gn at 267fps vs 453gn at 275fps , how much difference in point of impact at 50 yrds .

Archer’s Advantage. It’s $12/year.

Just noticed location

You will have to do just the opposite to all information. Everything goes the other way down under. LOL

AA is about the best program. that said, it is really hard to calculate without an archery program of this sort because every single component on every single arrow will have a different effect on an arrow's trajectory. if you don't want to purchase the program, all you can do is establish what is the most commonly used component for the type of arrow you want to build and tune your bow to that arrow. to be honest,....if you use typical components, you will get arrows that will provide typical performance and will, for all practical purposes be completely adequate if the bow is properly tuned to them. within the spectrum of typical components there really isn't any particular combination that will make one combination really stand out from the others, but is more potential to build an arrow that will under-perform from a poor combination of components, so deviating from what is typical, just to have something that is different,.... is not necessarily, a good idea. IOW building what everyone else has and uses has been established as a fairly good combination of components.

Buy some different weight points and shoot them at 50 yards, you are looking at about 2 " difference
