00:00There's no universal figure. The required annual investment depends on your target sum.
00:05Time horizon, an expected rate of return, calculated via the future value formula.
00:10FV equals PMT times. Open parenthesis 1 plus or close parenthesis to the power of N minus 1
00:18slash R. For example, to reach $500,000 in 30 years at a 7% average annual return,
00:25roughly the S&P 500's long-term historical average after inflation is closer to 6.5 to 7%.
00:32You'd need to invest about $5,940 per year, $495 slash month. Cut the horizon to 15 years at the
00:41same return, and the requirement jumps to roughly $19,900 per year, since compounding time is
00:48reduced. Key variables that shift this answer. 1. Time horizon. Every 10 years removed from your
00:55timeline roughly doubles or triples the annual contribution needed to hit the same target
01:00due to loss compounding. 2. Expected return. A 4% safe portfolio, bonds heavy, versus a 7-8%
01:09equity-heavy portfolio can change required contributions by 30-50% for the same goal.
01:153. Starting capital. If you already have savings invested, the PV, present value,
01:21offsets part of the annual requirement. A $50,000 head start at 7% over 20 years alone grows to
01:28$193,000,
01:31reducing what you need to add. 4. Risk tolerance and account type. Location matters here. Tax-advantaged
01:38accounts for O1K slash IRA in the US, ISA in the UK, or local equivalents. Change the effective return
01:46after tax, so the nominal contribution needed can differ by jurisdiction. I don't have your specific
01:52goal amount, timeline, or risk profile, so I can't give you a single number. And this isn't financial
01:58advice, just a factual framework. Practical next step. Define your target amount and year. Pick a
02:04realistic expected return based on your actual asset allocation. Then plug those into the formula
02:10above or a compound interest calculator to get your precise annual figure. Finally, remember that
02:16everything we discussed today is for educational purposes only and does not constitute financial
02:22advice. Good luck to everyone and see you in the next video.
