How do you know if you're saving enough for retirement in Singapore?

Curious what this group uses to track retirement readiness. Most calculators I've seen online don't account for CPF properly — especially MA overflow rules and CPF LIFE payouts.

I've been using the 25x rule as a rough guide (25x annual retirement expenses = your Freedom Number), but keen to hear how others approach this.

Also built a free 60-second quiz to get a quick score if anyone wants to try: danihokup.gumroad.com/l/retirement-check-free
