The savings calculator shows how much a lump sum or regular monthly contribution grows over time at a given interest rate. It uses compound interest to show the full growth of your savings, including the effect of contribution frequency and compounding schedule.
Future Value Formula
FV = PV x (1 + r)^n + PMT x [(1 + r)^n - 1] / r
FV = future value. PV = starting amount. r = periodic rate. n = periods. PMT = regular contribution. Example: $5,000 starting amount, $200/month, 5% annual rate, 10 years. FV = $8,193 + $31,056 = $39,249.
Growth of Monthly Contributions at 5% Annual Rate
| Monthly Contribution | 5 Years | 10 Years | 20 Years | 30 Years |
|---|---|---|---|---|
| $100 | $6,829 | $15,593 | $41,275 | $83,226 |
| $200 | $13,658 | $31,186 | $82,549 | $166,452 |
| $500 | $34,144 | $77,964 | $206,373 | $416,129 |
| $1,000 | $68,289 | $155,929 | $412,746 | $832,258 |
High-Yield Savings vs. Standard Savings
A standard savings account at 0.5% APY grows $10,000 to $10,512 over 10 years. A high-yield savings account at 4.5% APY grows the same $10,000 to $15,530 over 10 years. The difference is $5,018 with no extra contributions. Always maximize the rate on your savings, especially for cash you plan to hold for 1 year or more.
Emergency Fund vs. Investment Savings
Keep 3-6 months of living expenses in a liquid, accessible savings account. Do not invest your emergency fund in the stock market. Beyond the emergency fund, money you will not need for at least 5 years is better served in investments (stocks, index funds) rather than savings accounts, due to the higher expected long-term returns.
Frequently Asked Questions
How much will my savings grow in 10 years?⌄
It depends on the rate and whether you make additional contributions. $10,000 at 4% with no contributions grows to $14,802. The same amount with $100/month added grows to $29,644. Use this calculator with your starting balance, monthly contribution, and expected rate for an exact projection.
What is compound interest in a savings account?⌄
Compound interest means the interest you earn also earns interest in future periods. A savings account that pays 4% APY compounds either daily or monthly. Over time, compounding grows your balance faster than simple interest, even at the same rate.
How much should I have in savings?⌄
For an emergency fund, aim for 3-6 months of essential expenses in a liquid savings account. For short-term goals (1-3 years), keep that money in savings or CDs. For long-term goals (5+ years), investing in diversified funds typically produces better outcomes than saving alone.
What is the best savings account interest rate?⌄
High-yield savings accounts (HYSAs) at online banks typically offer the highest rates, often 4-5% APY in current markets. Traditional bank savings accounts often pay 0.01-0.5%. CDs (certificates of deposit) may offer higher fixed rates but lock up your money for a set term.
How long will it take to save $10,000?⌄
Divide the goal by your monthly savings amount. Saving $500/month reaches $10,000 in 20 months. Saving $300/month takes about 33 months. If your savings earn interest, the timeline shortens slightly. This calculator shows the exact date based on your contribution and rate.
