How Savings Goals Work
A savings goal is a target amount you want to accumulate over time. Reaching it depends on three factors:
- Starting balance — money you have already saved gives you a head start.
- Monthly contributions — regular deposits are the engine that drives progress toward your goal.
- Interest rate — earning interest on your balance (and on previously earned interest) accelerates growth through compounding.
The higher your contributions and interest rate, the faster you reach your target. Even a modest rate of return can shave months or years off your timeline because each month's interest is added to the balance before the next month's interest is calculated.
How Long It Takes to Reach a Savings Goal
When interest is compounded monthly, the number of months needed to grow from a current balance to a target goal is:
When the interest rate is 0%, the formula simplifies to: n = (G − C) / M (the remaining amount divided by the monthly deposit).
This calculator uses a month-by-month simulation to determine the exact month your balance reaches or exceeds the goal, which handles rounding and edge cases more accurately than the closed-form formula above.
Example Savings Plan
Suppose you want to save $50,000, you currently have $5,000, you can contribute $500 per month, and your savings earn 5% annual interest.

Frequently Asked Questions
What if I can never reach my goal?
If your monthly contribution is zero and your current savings are below the goal with a 0% interest rate, the goal is unreachable. The calculator will let you know. To fix this, increase your monthly contribution or aim for a higher return through investing.
Does this calculator account for inflation?
No. The results are in nominal (today's) dollars. If you want to account for inflation, subtract the expected inflation rate from your interest rate. For example, use 3% instead of 5% if you expect 2% annual inflation.
What interest rate should I use?
Use the annual percentage yield (APY) of the account where you plan to save. High-yield savings accounts typically offer 3%–5%, while diversified investment portfolios have historically averaged 7%–10% before inflation. Use a conservative estimate to avoid overestimating your timeline.

Build a Long-Term Savings Habit
Reaching your savings goal is easier when you automate the process. Setting up automatic monthly transfers to a high-yield savings account helps you stay consistent and lets compound interest work in your favor over time.
What to Look For in a High-Yield Savings Account
High-yield savings accounts (HYSAs) pay significantly more than traditional bank savings accounts while keeping your money liquid and FDIC-insured. Key factors when comparing options:
- APY vs. APR — the annual percentage yield reflects compounding and is the correct figure to compare across accounts; always use APY
- Promotional vs. ongoing rates — some accounts offer a high introductory rate that drops after a few months; confirm the standard ongoing rate before committing
- FDIC or NCUA insurance — confirm your savings are insured up to $250,000 per depositor per institution through a federally regulated insurer
- Transfer speed — some online banks take 2–3 business days to move money to your checking account; confirm this works for your cash-flow needs
- Minimum balance requirements — some accounts require a minimum balance to earn the advertised APY or to avoid monthly fees
