How does this calculator work?
Each month your balance grows as B = B × (1 + r/12) + PMT until it reaches your goal. With $5,000 saved, $1,000/month and 5% annual return toward a $50,000 goal: roughly 3.5 years. Higher contributions or returns shorten the timeline sharply due to compounding — enter your numbers for a personalised projection.
Formula
How this is calculated
The calculator simulates your savings balance month by month: it starts with your current savings, credits one month of compound interest and adds your monthly contribution, then repeats until the balance reaches your goal or 50 years (600 months) elapse. Using monthly compounding with annual rate r gives monthly rate r/12, producing the recurrence Balance(t) = Balance(t−1) × (1 + r/12) + PMT.
The annual return rate is an estimate you control. Use 0% for a cash current account or basic savings account, 3–4.5% for a high-yield savings account or government bonds (rates vary by country and year; this tool uses a flat rate), and 5–7% for a low-cost global equity index fund over a long horizon — these are historical averages, not guarantees, and actual returns fluctuate. If your goal is a real-world purchase rather than a cash target, consider subtracting expected inflation from the return rate to work in real terms.
If you already have enough saved, the calculator reports 0 months with a congratulatory message. If the monthly contribution plus interest can never bridge the gap within 50 years, it returns no result — in that case, increase the monthly amount, raise the expected return, or adjust the goal.
Frequently asked questions
Use 0% for a cash savings account; ~3.5–4.5% for government bonds or a high-yield savings account (as of 2025, rates vary by country); ~5–7% for a low-cost global equity index fund over a long horizon. Investment returns are variable and not guaranteed — treat the output as a planning range, not a promise.
This calculator uses a fixed monthly contribution. To model income growth, run it again with a higher contribution to see the revised timeline. Even small increases compound significantly: adding $100/month to a $1,000 monthly plan can cut years off a long-term goal.
If your dream is a real-world purchase (car, house, holiday) that will cost more in future money, inflate the goal or subtract expected inflation from the return rate to obtain a real return. For example, a 6% nominal return with 3% inflation gives a 3% real return to enter here, and the goal amount should be today's price.
