I am working on a financial model of my startup and would like to make good predictions on how much I spend on a channel (FB,Instagram, Google Ads etc.) and what is the return rate of leads etc/ of that channel. Hubspot ROI Calculator looks simple.
Any ideas on that? or any recommendations tools you are using.

Sounds like you have no data to work with already? Your basic ROI calculations are fine and there's nothing wrong with making that yourself in excel, if you're planning.
Just be sure to take your keyword CTR, industry average BR, average conversion value and you should more or less be set to plan.
Like everyone else here is saying though, make sure you start analysing your data as soon as you can to make revisions and tweak your model.
Google ads has great analytics, and you can upload costs in GA to give you ROI or ROAS. If you want to take it one step further you could connect it to Data studio and upload all your external data to give you a really robust picture.
Hope that helps!
