Investment numbers that look different after the math
Scenario-driven notes about compounding, drawdown recovery, and market moves that become easier to understand once the numbers are calculated.What does 0.5% a day do to your money in 100 days?
$1,000 at 0.5% a day for 100 days becomes about $1,647. At 0.7% a day, it becomes about $2,009.
What happens to $1,000 after 5 years at 0.1% a day?
The first day adds only $1 to $1,000. But at 0.1% compounded daily, the money becomes about $1,440 after 1 year and $6,197 after 5 years.
1.0% vs 1.1% a day: how much is the gap after a year?
$1,000 at 1.0% a day becomes about $37,783 after one year. At 1.1% a day, it becomes about $54,222, a gap of about $16,438.
What daily return recovers a 50% loss in 100 days?
If $1,000 falls to $500 after a 50% loss, recovering to $1,000 in 100 days requires about 0.6956% a day compounded.
-80% loss, +400% recovery
An 80% loss takes $1,000 down to $200. To get back to $1,000, the remaining money needs a +400% gain.
How long until $1,000 becomes $100,000?
$1,000 needs 463 days at 1% a day to pass $100,000. At 2%, it takes 233 days. The same target feels very different when the daily return changes.
How much does a 1% fee cost over 30 years?
$10,000 at 8% for 30 years becomes about $100,627. At 7%, it becomes about $76,123. That 1% gap costs about $24,504.
What if your money earns 1% every day for a year?
A $10 first-day gain can turn into a much larger number when the same return compounds for a year. $1,000 becomes about $37,783 after 365 days.
Why does a 50% loss need a 100% gain?
A 50% loss cuts $1,000 to $500. To get back to $1,000, the remaining money must double, which means a 100% gain.
What happens to $1,000 after five Korean limit-up days?
Five 30% gains are not a 150% return. $1,000 becomes about $3,713 because each gain is applied to the higher amount from the day before.
