How much should I be saving if I'm 24 years old and am currently on a 1-year contract with $2,240 take-home pay?

Breakdown of expenses:

• $400 (daily)
• $85 (bills)
• $161 (insurance)
• $200 (savings plan)

Not be getting married/BTO anytime soon. Parents expect me to give them money every month (amount at my discretion).

I read online that I should be saving 20% of my income, but I think it's too low.

I'd love to have guidance on how much I should be saving (& how much to give my parents).

And perhaps where is the best place for me to channel these savings. Thanks!
