[28M Andhra]Help with saving and investing - Salary 2.5 to 3LPM

Remote software dev, earning in USD and spending in INR

I get paid anywhere in between 2.5 to 3LPM, depending on the number of hours I work. My spendings are as below

• Household expenses - 35k
• Phone, internet and other bills - 5k pm
• Gold - 15k pm
• MFs - 10k pm
• Misc expenses - 20k
• If I travel that month - 30-40k

I don't have any loans to pay off. We also built a house recently. I'm being left with 1.5L almost every month and I'm just leaving it in my savings account. How do I manage my finances better?
