The answer depends entirely on your goal and timeline. Here's how to calculate the exact monthly savings amount needed for any retirement date.
Enter your target to see required monthly savings
If you want to retire at the conventional age (65+), saving 15–20% of gross income is the standard recommendation. For early retirement (50–55), aim for 30–40%. For FIRE in your 40s, 45–55%. These percentages assume investing in equity index funds returning roughly 7%/year.
The most reliable savings strategy: automate a fixed transfer to investments the day you get paid. Treat it like rent — non-negotiable. Then live on what remains. People who save "what's left at the end of the month" consistently save less than they intend to.
