Addition and multiplication

Give income and investing different jobs

Rent, food, and utilities keep returning. Pay from work or a business can bring money in repeatedly to meet them. In my framework, that recurring cash flow is addition.

A job or business can still change. The aim is to build a more predictable way to cover recurring costs, not to pretend any income is guaranteed. A monthly plan needs both the amount and the timing to make sense.

Money committed to an investment is called capital. I use multiplication to mean trying to grow that invested capital. A successful investment can produce a larger sum, but it can also lose value. You do not control when the market will rise.

A gain on a price screen is not the same as cash you have received. If the price rises while you still own the asset, the gain is unrealized. Selling can turn it into a realized gain, with costs and any tax still to consider.

I want addition to support your life while you pursue multiplication. Use the plan to decide what can go toward investments after your other needs. Do not rely on selling at a higher price on the exact day a bill is due.

Regular income can also fund investment contributions. Putting in $75 each month for twelve months adds $75 × 12 = $900 of your own money. That $900 is a contribution, not a profit made by the investment.

A second gain uses the new balance

Start with an invented $200 investment. A 10% gain adds $20, because 10% of $200 is $20. The new balance is $220.

Leave all $220 invested and suppose it gains another 10%. This time the gain is $22, because the percentage applies to $220. The balance becomes $242. The second gain is larger because the amount it acts on is larger.

This process is called compounding. Gains left invested can earn further gains. In the example, there are no new contributions, withdrawals, fees, or taxes, so you can see that one effect clearly.

Real investments do not deliver a smooth, certain 10% each period. The gain may be smaller, or there may be a loss. And until you sell and receive usable cash, a price gain is still different from money available for a bill.

A loss changes the next percentage too

Now start again with $200 and lose 25%. That loss is $50, leaving $150. If the investment then gains 25%, the gain is calculated on $150, not on the original $200.

Twenty-five percent of $150 is $37.50. Add it back and you have $187.50. You lost 25% and gained 25%, yet you are still below $200 because the two percentages used different starting amounts.

This is one reason to think about losses as carefully as possible gains. A percentage on its own is not enough. Ask what dollar amount it applies to and how much would be needed to recover.

Match the money to its deadline

Suppose you need a housing deposit in six months. Start with the amount required and the date it must be ready. A high projected return does not help if the investment falls when you need to pay.

A fund holding many companies spreads money across them. This is called diversification, and it reduces dependence on any one company. The whole fund can still fall, even if its fees are low.

For money needed soon, think about access and keeping the required amount available. A crypto projection cannot promise a housing deposit on time. Planning asks about protected cash before suggesting investment amounts for this reason.

Addition and multiplication can work together, but they have different jobs. Build recurring income for recurring needs, and understand the risk of the money you invest. The strategy later in the course builds on that distinction.
