How the savings goal projection works
This calculator solves the future value of savings formula in reverse: instead of asking "how much will I have," it asks "how long until I have enough." Starting from your current balance, it adds your monthly contribution every month and compounds the whole balance at your annual interest rate, then finds the exact month your total first meets or exceeds your goal.
A higher interest rate or a larger existing balance both shrink the timeline, but the effect is small for short-term goals and grows the longer your money has to compound. That's why a $20,000 emergency fund goal reached in under two years is driven almost entirely by your monthly deposits, while a 10-year house down payment goal leans much more heavily on interest.
The formula
i = annual rate ÷ 12 (monthly rate)
months to goal = ln[ (goal + contribution ÷ i) ÷ (current + contribution ÷ i) ] ÷ ln(1 + i)
if i = 0: months to goal = (goal − current) ÷ contribution
months to goal = ln[ (goal + contribution ÷ i) ÷ (current + contribution ÷ i) ] ÷ ln(1 + i)
if i = 0: months to goal = (goal − current) ÷ contribution
Worked example
You want to save $20,000, starting from $2,000, adding $300 a month at a 4% APY savings rate. Solving the formula gives roughly 54 months (about 4.5 years). Over that time you'll personally contribute about $16,200, and the remaining ~$1,900 comes from interest, a modest but meaningful boost since a savings-account rate compounds more slowly than the pace of your own deposits.

Frequently asked questions
How do I calculate how long it takes to reach a savings goal?
Enter your goal, current balance, monthly contribution and interest rate; the calculator solves for months to goal.
What interest rate should I use?
3.5%-4.5% for a HYSA, under 0.5% for a standard bank account, 6-7% for a long-run brokerage estimate.
How much comes from interest vs my contributions?
Mostly contributions for short goals; interest matters more the longer your timeline runs.
How much should I save monthly to hit my goal?
Adjust the monthly contribution field and watch the months-to-goal update instantly.
Can I use this for an emergency fund?
Yes, set the goal to 3-6 months of expenses and see how long it takes to fully fund it.
Does this account for taxes on interest?
No, it uses your gross rate; taxable interest income will lower your real after-tax growth slightly.
