The 5 Variables of Wealth

Income

The foundation — earning capacity

The foundation of the wealth formula — without income, there's nothing to save or invest. Income comes in three forms: earned (job), business (ownership), and passive (investments). The fastest path to wealth: increase income through skill development, career advancement, or business growth. Each $1,000/month increase in income, invested at 10%, = $230,000 over 15 years.

Savings Rate

What percentage you keep and invest

What percentage of income you keep and invest — the single most predictive factor of financial independence. A 10% savings rate = 51 years to FI. A 50% savings rate = 17 years. A 75% savings rate = 7 years. The formula: years to FI ≈ (1/savings rate) × adjustment factor. Savings rate matters more than income — a $50K earner saving 30% reaches FI faster than a $200K earner saving 5%.

Return Rate

Your investment growth rate

Your investment growth rate — the multiplier on your savings. A 7% real return (inflation-adjusted) is a reasonable long-term expectation for diversified stock portfolios. Each 1% increase in return rate dramatically compresses the timeline: $500/month at 7% for 30 years = $607K; at 10% = $1.1M; at 12% = $1.5M. But chasing high returns introduces high risk — the extra 2% isn't worth a 50% drawdown.

Time

The most powerful variable — compounding

The most powerful variable in the wealth formula — and the one you can't manufacture. $10,000 invested at 10% for 10 years = $25,937. For 20 years = $67,275. For 30 years = $174,494. For 40 years = $452,593. The lesson: start NOW. A person who invests $5,000/year from age 20-30 and then STOPS will have more at age 60 than someone who invests $5,000/year from age 30-60.

Leverage

Using other people's money and resources

Using other people's money (OPM) to amplify returns. A $300K property bought with $30K down that appreciates 5% = $15K gain = 50% return on your $30K. But leverage amplifies losses too — a 5% decline = $15K loss = 50% of your equity gone. Types of leverage: mortgage debt (real estate), margin (stocks), SBA loans (business), seller financing (notes). Rule: only use leverage on appreciating, cash-flowing assets.

Wealth Calculator

Project your wealth using the 5 variables

Project your wealth using the 5 variables: current income, savings rate, return rate, years to invest, and leverage multiplier. The calculator shows: given your inputs, when will you reach financial independence? Adjust one variable at a time to see its impact. The most controllable variables: savings rate (reduce expenses) and income (skill development).

Savings Rate Optimizer

Find your optimal savings rate

Find your optimal savings rate — the balance between aggressive saving and quality of life. The optimization: every 1% increase in savings rate compresses the FI timeline by roughly 1 year (at moderate rates). But diminishing returns exist — going from 50% to 60% saves fewer years than going from 10% to 20%. Find the rate you can sustain long-term.

Compound Interest Simulator

See the power of time and compounding

See the power of time and compounding visually. The simulator shows: early contributions grow exponentially (the 'hockey stick' curve), while late contributions barely grow. The key insight from Einstein (allegedly): 'Compound interest is the eighth wonder of the world. He who understands it, earns it; he who doesn't, pays it.'

Leverage Analyzer

Understand the risks and rewards of leverage

Understand the risks and rewards of leverage through scenario analysis. Positive leverage: borrowing at 4% to invest at 10% = 6% spread = positive. Negative leverage: borrowing at 8% to invest at 6% = -2% spread = wealth destruction. The analyzer shows: at what return rate does leverage become profitable? At what point does the risk of ruin (margin call, foreclosure) become unacceptable?
