💡 What This Means
HYSA Compounding Calculator
The HYSA Compounding Calculator shows the cost of leaving cash in a big bank account paying almost nothing. You enter a starting deposit, a monthly addition, the yield on a high-yield account, and a time horizon, and it returns your ending balance, the interest earned, and how far ahead you finish compared to a 0.01% account. Use it when you have an emergency fund or a savings balance sitting idle. Moving the same dollars to a high-yield account costs you nothing and adds hundreds or thousands in interest over a few years, with no extra risk. The side-by-side line makes the gap obvious and gives you a clear reason to switch.
