Enter a savings goal, what you already have, and how much you can add monthly to see exactly when you'll hit it, including interest if the money sits in a high-yield savings account.
Why interest rate matters more than people assume for short-term goals
For a goal you'll reach within a year or two, interest makes a small difference. For goals stretching three, five, or ten years out, that gap widens fast because interest compounds on interest, not just on your contributions. Keeping a multi-year savings goal in a checking account instead of a high-yield savings account is one of the more common places people leave free money on the table without noticing.
A concrete example
Saving $300 a month toward a $10,000 goal, starting from $1,500, with 0% interest takes about 29 months. The same numbers at 4.5% APY, a realistic high-yield savings rate, cut that down to roughly 27 months, about two months faster for doing nothing except picking a better account. On bigger goals or longer timelines the gap grows: a 5-year goal can shrink by 4 to 6 months just from the interest rate difference.
What this doesn't account for
This calculator assumes a steady contribution every month and a fixed interest rate, which is a simplification. Real savings account rates move with the market, and real months are rarely perfectly consistent. Treat the output as a realistic planning estimate, not a guarantee, and re-run the numbers every few months as your rate or contribution changes.
This calculator gives estimates based on the numbers you enter and assumes a constant monthly contribution and interest rate. This article is for general informational purposes and isn't financial advice.
