Pro tips for investment growth
- Start early — compound interest has the biggest impact over long time horizons.
- Match compounding frequency to how your account actually credits interest.
- Use inflation adjustment to see real purchasing power, not just nominal dollars.
- Regular monthly contributions often matter more than chasing a slightly higher return rate.
- Review assumptions periodically; past returns do not guarantee future performance.

How much will your investment grow?
Compound interest can turn steady saving into serious wealth over time.
- $1,000 at 7% for 10 years → about $1,967
- $10,000 at 8% for 20 years → about $46,610 (lump sum only)
- $10,000 + $200/month at 8% for 20 years → $150,000+
Use the calculator below to get your exact future value based on starting amount, contributions, rate, and time.
What Is a Future Value Calculator?
A future value calculator helps investors, savers, and planners estimate how much money an investment or savings account will be worth at a future date—fast.
You enter your initial investment, monthly contributions, annual interest rate, time period, and optional settings like compounding frequency, inflation, and withdrawals. The tool returns your total future value, interest earned, and a year-by-year breakdown instantly.
Getting the projection right matters. Underestimating contributions or ignoring inflation can leave you short of retirement goals. Overestimating returns can create false confidence.
How to Use This Calculator
Step 1 Initial investment
Enter the starting amount you invest or deposit today. Use 0 if you are modeling contributions only (for example, a new monthly savings plan with no lump sum).
Step 2 Monthly contribution
Add an optional recurring deposit each month. Even modest contributions compound significantly over long horizons—a $200/month deposit at 8% for 20 years adds far more than interest on the initial balance alone.
Step 3 Interest rate and time period
Enter your expected annual return (for example, 7% for a balanced portfolio or 4% for conservative savings) and the number of years you plan to stay invested. Decimal years are supported (e.g. 10.5 years).
Step 4 Compounding frequency
Choose how often interest is applied:
- Yearly — once per year
- Half-yearly — twice per year
- Quarterly — four times per year
- Monthly — most savings accounts and many investments
- Daily — some high-yield accounts
More frequent compounding produces a slightly higher future value at the same nominal rate.
Step 5 Inflation and withdrawals (optional)
Inflation rate — optional. Enter an estimate (often 2–3%) to see your result in today's purchasing power, not just nominal dollars.
Withdrawals — optional. Model monthly or annual withdrawals (for example, retirement income). Withdrawals reduce ending balance and are reflected in your result automatically.

Future Value Calculator Formula
The basic future value formula for a lump sum:
FV = PV × (1 + r)ⁿ
Where:
- FV = Future Value
- PV = Present Value (starting amount)
- r = Interest rate per period
- n = Number of periods
For monthly compounding at annual rate *R* over *t* years:
FV = PV × (1 + R/12)^(12 × t)
When you add regular contributions (PMT), the calculator applies the future value of an annuity formula on top of your lump sum:
FV = PMT × [(1 + r)ⁿ − 1] / r
You do not need to calculate this manually—the tool handles lump sums, contributions, compounding, inflation, and withdrawals together.
Future Value by Investment Scenario
Planning table (illustrative examples — your actual results depend on rate, compounding, and contributions):
| Starting amount | Rate | Years | Monthly contribution | Approx. future value |
|---|---|---|---|---|
| $1,000 | 5% | 10 | $0 | $1,629 |
| $5,000 | 7% | 15 | $0 | $13,766 |
| $10,000 | 8% | 20 | $200 | $150,000+ |
| $0 | 6% | 30 | $500 | $502,000+ |
| $25,000 | 4% | 10 | $100 | $40,000+ |

Common Use Cases
Retirement planning
Project how much your 401(k), IRA, Roth IRA, or TSP could be worth at retirement. Add monthly contributions to see how consistent saving accelerates your end balance.
Investment growth
Estimate future value of stocks, mutual funds, ETFs, or a brokerage account at different expected return rates. Compare how even a 1% difference changes outcomes over 20–30 years.
Savings account projection
See how a bank deposit grows with compound interest applied monthly. Model regular deposits to track how disciplined saving builds balance over time.
Education or major purchase goals
Work backward from a target date and amount—college fund, home down payment, or emergency fund—and test whether your current savings rate gets you there.
Troubleshooting Wrong Results
- Result too low? You may have forgotten monthly contributions or used an annual compounding setting when your account compounds monthly. Try raising the rate slightly or extending the time period.
- Result too high? Check that your interest rate is realistic (e.g. 7–10% for long-term stock averages, not guaranteed). Add inflation to see real purchasing power.
- Inflation-adjusted value missing? Enter an inflation rate in the optional field—without it, the calculator shows nominal dollars only.
- Withdrawals not reflected? Set withdrawal amount and choose monthly or annual frequency. Large withdrawals can significantly reduce ending balance.
Frequently Asked Questions
How do you calculate future value?
Multiply your present value by (1 + interest rate) raised to the number of periods: FV = PV × (1 + r)ⁿ. For example, $1,000 at 7% for 10 years ≈ $1,967. This calculator handles lump sums, contributions, and compounding automatically.
How do you calculate future value in Excel?
Use Excel's FV function: `=FV(rate, nper, pmt, pv)`. For monthly compounding at 6% over 10 years on $1,000: `=FV(6%/12, 120, 0, -1000)` returns $1,819.40. Divide the annual rate by 12 and multiply years by 12 for monthly periods.
How do you calculate the future value of an annuity?
Use FV = PMT × [(1 + r)ⁿ − 1] / r. For example, $200 per month at 6% for 10 years grows to about $32,776. Enter your monthly contribution in this calculator and it applies the annuity formula for you.
How do you calculate future value with compound interest?
Use FV = PV × (1 + r/n)^(n×t) where *n* is compounding periods per year. Monthly compounding at 6% means dividing 0.06 by 12. More frequent compounding yields a higher future value at the same nominal rate.
How do you calculate future value of money with inflation?
Subtract inflation from your nominal return for a real rate, or enter an inflation rate in this calculator to see inflation-adjusted value in today's dollars. If you earn 8% and inflation is 3%, real growth is roughly 5%.
How do you calculate future value of a savings account?
Enter your current balance as present value, your bank's annual interest rate, monthly compounding (typical for savings), years, and any regular deposits. The calculator shows exactly how much your account will be worth at any future date.
What is a good expected return rate to use?
Conservative planning often uses 3–5% (savings/bonds), moderate 6–8% (balanced portfolios), aggressive 9–10%+ (heavily equity). Past performance does not guarantee future results—use a range and stress-test with lower rates.
Summary
Enter your initial investment, monthly contributions, interest rate, time period, and optional inflation or withdrawals—then get your future value projection instantly. Plan with realistic assumptions, and consult a licensed financial advisor for personalized advice.
