Make your goal fund work harder

A high-yield savings account pays several times the average rate - on a $20,000 balance that's hundreds of dollars a year for zero extra effort.

How the monthly amount is calculated

Your existing savings grow at the interest rate you enter, and each monthly deposit earns interest for the months that remain. The calculator solves for the deposit amount whose future value, plus the growth of what you've already saved, exactly equals your goal on the target date.

Goal = Current × (1+i)n + Deposit × [ ((1+i)n − 1) / i ]

where i is the monthly interest rate and n the number of months. If your current savings alone will grow past the goal, the required deposit is zero - you're already done.

Frequently asked questions

How big should an emergency fund be?

Three to six months of essential expenses is the common guideline, kept liquid in a high-yield savings account. One month is a great first milestone.

Where should I keep goal savings?

For goals within ~5 years, high-yield savings or CDs - safe and interest-bearing. Longer-term money can be invested; see the compound interest calculator.

Does the interest rate matter much?

For short timelines the monthly amount dominates, but 4% vs 0.5% still adds up on bigger balances - it's free money for a one-time account switch.
