A low interest rate of about 1% greatly weakens the power of compounding because your money grows very slowly and the “interest on interest” effect stays small even over many years.

What this means in practice

  • With compound interest, you earn interest on your original money and on the interest that has already been added.
  • At only 1%, each year’s interest is tiny, so future interest has very little to build on.
  • The growth curve stays almost flat instead of turning sharply upward like it does at higher rates (for example, 4–5%).
  • Over long periods, the difference between 1% and higher rates can add up to thousands of dollars in missed growth.

Is this good or bad for Ben?

  • For savers like Ben, a 1% rate is generally bad for compounding because his savings won’t grow much beyond what he deposits himself.
  • It can still be useful for short-term, safe parking of cash (like an emergency fund), but it is not powerful for long‑term wealth building.

In simple terms: at 1%, compounding is technically happening, but it’s so weak that time doesn’t help Ben nearly as much as it would at a higher rate.

TL;DR: A 1% interest rate makes the power of compounding very weak, so Ben’s savings will grow slowly and the “snowball” effect of interest on interest will be minimal.
