# What $1,000 can become

> A simple example of compound interest — and why starting early matters more than starting big.

Most of us are taught to save. Far fewer are taught what saving *as cash* quietly costs — or how much ordinary money can grow when you give it time. Here's the idea in plain numbers.

## Money left idle doesn't stand still

Say you set aside **\$1,000** and leave it as cash. The number on the screen stays \$1,000 — so it feels safe. But prices rise every year. At around 3% inflation, prices more than double over 30 years — rising roughly 2.4× — which means that untouched \$1,000 will buy only about **\$410** worth of today's goods by the time you retire.

Doing nothing isn't neutral. It's a slow, quiet loss.

## What the same \$1,000 does when it's invested

Now imagine that \$1,000 is invested and earns an average of **7% a year**. Each year's gain is added to the balance, and the next year's growth is calculated on the larger amount. That's **compound interest** — growth earning growth.

| After…   | Left as cash | Invested at \~7% / yr |
| -------- | ------------ | --------------------- |
| 10 years | \$1,000      | \~\$1,970             |
| 20 years | \$1,000      | \~\$3,870             |
| 30 years | \$1,000      | \~\$7,610             |

Same starting amount. The only difference is whether it was working for you.

## The real magic is the habit

One \$1,000 is a nice illustration — a habit is what changes a life. Invest **\$1,000 a year** at that same 7%, and after 30 years you'd have around **\$94,000** — even though you only put in **\$30,000** of your own money. The other \~\$64,000 is pure growth.

This is the good news hiding behind a scary-sounding retirement number: reaching it isn't about extraordinary returns or a big salary. It's about **time**.

## Why starting early beats starting big

Time is the one ingredient you can't buy back. Wait ten years to begin, and the same \$1,000-a-year habit grows to only about **\$41,000** instead of \$94,000 — less than half. You skipped just \$10,000 of contributions, but it cost you more than **\$50,000** at the finish line.

<Note>
  The earlier you start, the more of the work compound interest does for you — and the less you have to sacrifice today to reach the same goal.

## See it with your own numbers

These figures are a simple illustration — your real income, expenses, and goals are unique to you. That's what **Financial Plan** is for: it runs this same math on *your* assets, contributions, and life events, so you can see where you're heading and test what changes when you start sooner or set aside a little more.

<Note>
  Figures are illustrative and assume a steady 7% annual return and 3% inflation. Real returns vary year to year, investing carries risk, and this isn't financial advice — it's a way to understand how time and compounding work.
