Deposits move the balance because you add cash. APY growth (when you model it) adds interest each month on the balance already saved.
Sample: $10,000.00 goal · $200.00/month · start $0
- 0% APY: 4 years 2 months (50 months) · deposits $10,000.00 · interest $0.00
- 4% APY input: 3 years 11 months (47 months) · deposits $9,400.00 · interest $743.83
