Applying Financial Math to Real Scenarios

A higher compounding frequency generally:

• Lowers effective return

• Raises effective return

• Eliminates risk

• Reduces taxes

If a loan has a 6% interest rate, that means:

• You gain 6% annually

• You owe 6% of the remaining balance each year

• The bank loses 6%

• Inflation sets the rate

The book’s retirement projections highlight:

• The final decade contributes the least

• Early contributions dominate long-term growth

• Only high earners benefit from investing

• Cash savings outperform investments

When the real interest rate is negative:

• Purchasing power decreases

• Purchasing power increases

• Inflation disappears

• Stocks stop compounding

Time Value of Money calculations emphasize:

• Timing decisions early matters immensely

• Inflation has no role

• Future dollars are more valuable

• Spending is more important than saving

The longer money stays invested:

• The smaller the compounding effect

• The larger the compounding effect

• The more inflation destroys value

• The more it depends on salary

The book uses multi-year examples to teach that:

• Debt is always beneficial

• Growth accelerates over time

• Savings accounts outperform stocks

• Inflation is predictable

Depreciation matters because:

• It affects asset resale value

• It increases taxes

• It eliminates risk

• It grows money

PV calculations show that:

• Future money is worth less today

• Future money is worth more today

• Inflation increases PV

• Interest is irrelevant

The biggest influence on future value is:

• Frequency of withdrawals

• Length of time invested

• Credit score

• Type of bank account
