Standard investment formulas
Our investment calculators use widely accepted financial formulas — including compound interest, CAGR, and XIRR methods — aligned with the standards used across the MoneyTool Learning Center.
Estimate potential investment growth, compare contribution scenarios, and understand returns with our free investment calculators. Explore how time, compounding, and regular investing may affect your long-term financial goals.
Investing involves making decisions about money with the expectation that it may grow or generate income over time. The outcome depends on many factors — the amount invested, contribution frequency, investment period, assumed rate of return, fees, taxes, and market conditions. Understanding these variables can help you make more informed decisions.
MoneyTool's SIP calculator, CAGR calculator, and ROI calculator help turn these concepts into easier-to-understand numbers. By entering different assumptions, you can explore how compound growth, regular contributions, and time may affect a potential future value.
These tools are particularly useful for comparing scenarios. For example, you can examine what happens when you increase a regular contribution, extend the investment period, or use a different assumed rate of return. Calculator results are estimates rather than promises of future performance.

Enter the initial amount you are considering investing, if the calculator requires one.
Include monthly, annual, or other regular contributions when supported.
Select a realistic investment period and consider how the time horizon affects results.

Common questions about investment calculations, compounding, and projected returns.
Depending on the calculator, you can estimate potential future value, investment returns, compound growth, regular contribution growth, or return-related measures. Results depend on the assumptions and inputs you provide.
No. Investment calculators generally use simplified assumptions to produce estimates. Actual investment performance can vary because markets, interest rates, fees, taxes, and other conditions can change.
Compounding means that returns may become part of the amount on which future returns are calculated. Over longer periods, this can have a significant effect on an estimated future value.
Not necessarily. Higher potential returns generally involve different levels of risk, and a calculator does not measure whether a particular investment is suitable for you. Assumed returns should be treated as scenarios rather than guarantees.
CAGR measures a single investment's annualized growth rate over time. XIRR handles irregular cash flows — multiple contributions or withdrawals at different dates — and gives a more accurate return for those cases.
No. Saving typically means setting money aside in a low-risk account. Investing means putting money into an asset with the expectation of growth — but also with risk of loss. Both have a role in a financial plan.
Inflation reduces purchasing power over time. Even if an investment grows in nominal terms, its real value may be lower after inflation. Using an inflation-adjusted return provides a more realistic picture.
