There are additional functions within excel as "add ins" such as Goal Seek.
Though if you are after increased visibility into each project with minimal transactional entries to read from you will most likely need to develop a basic dashboard yourself within excel.
I have many dashboards that i have built for my company (unfortunately i cannot forward examples) however if your after basic ratios conversions etc... you will be best off googling for each particular measure that you would like to have within the dashboard. this would only be a time commitment rather than a $ commitment for you to establish within the company.
Pivot Table Formulas are also a good use when you start to group the particular instances in the transactions as once you have set it up you can simply overwrite the current pivot table source and refresh the table to see the new data with the measures in place.
