Tell us your goal and we'll work backwards: how much you need to save each month, given your starting balance and the APY on your savings account.
We compute the future value of your starting balance, subtract it from the goal, then solve the annuity formula for the recurring deposit needed.
Goal $50,000 in 5 years, $5,000 starting, 4.5% APY: about $651/month. Park it in a high-yield savings account.
