This MayeleCalc guide explains the concept in plain language so you can use the related calculator with better context and confidence. Work through each section, review the practical example, and check the common mistakes before applying the result.
Growth earns growth
Compounding means returns can be earned on both the original principal and earlier returns. Over long periods this creates nonlinear growth.
Contributions change the picture
Regular contributions add new principal throughout the timeline. Starting earlier can allow more contribution periods and more time for each deposit to grow.
Use realistic assumptions
Investment returns are not guaranteed. Test conservative, moderate, and optimistic rates, and consider fees, taxes, and inflation before making a plan.
Practical example
See the idea in action
Compare at least three scenarios using the same starting amount. Change only one input at a time—such as the rate, term, or monthly contribution—so you can see exactly what drives the result.
Common mistakes to avoid
- ×Comparing monthly payment without comparing total cost
- ×Using an annual rate as though it were a monthly rate
- ×Assuming an investment return is guaranteed
Key takeaways
- ✓Small rate changes can become meaningful over long periods
- ✓A lower payment does not always mean a lower total cost
- ✓Transparent assumptions make comparisons more useful
