How To Use The Child Wealth Calculator (And What Return Rate Should You Use?)
One of the most common questions parents ask is:
"What number should I put for the return rate?"
If you're new to investing, terms like returns, index funds, and compounding can feel confusing.
This guide explains what the calculators mean, what return rates represent, and how to use each calculator on Child Wealth Calculator.
What Is A Rate Of Return?
A rate of return is simply how much an investment grows over time.
For example:
✓ Start with $100
✓ Earn an 8% return
✓ End with approximately $108
In real life, investments do not grow by the same amount every year.
Some years may be positive. Some years may be negative.
The calculators simply use an average annual return assumption to estimate potential future growth.
What Return Rate Should Parents Use?
Many parents are unsure what number to enter.
The table below shows common planning assumptions.
| Return Rate | Description |
|---|---|
| 4% | Conservative assumption |
| 6% | Moderate assumption |
| 8% | Common long-term stock market assumption |
| 10% | Aggressive assumption |
Most Parents Use 6% To 8%
For long-term planning, many parents use 6%, 8%, or 10% to see different scenarios.
Are These Returns Guaranteed?
Important
No investment return is guaranteed.
The stock market rises and falls over time. These calculators are educational tools and not predictions of future performance.
Which Investments Are These Calculators Designed For?
Most parents using these calculators are estimating potential growth from broad stock market index funds.
Examples include:
✓ VOO
✓ IVV
✓ VTI
✓ SPLG
These funds attempt to track large groups of companies rather than selecting individual stocks.
The calculators can be used for many investment scenarios, but they are most commonly used with long-term index fund investing assumptions.
