Determining the Earnings growth of the Portfolio

Dear Friends,

Kindly let me know any tools or website available to determine the earnings growth of the portfolio as a whole given the stocks with different weightage & also different growth rate.

If not for tools , also let me know of formulas that we can use to calculate the same manually.

I think should check trendlyne app

SUM(profit growth of stock*weightage%)
2 stock portfolio with 80% say in HDFC Bank and 20% in Airtel
Hdfc bank profit growth = 25%
Airtel profit growth = 15%

Portfolio profit growth = (25x0.8 + 15x0.2) = 23%


Thank you so much Nitish, was looking for this formula!
