Calculators

Pick the calculator based on your question: SIP for monthly investing, Lumpsum for one-time investing, CAGR for start-to-end growth rate, XIRR for real portfolio return with dates, Present Value to convert future price to today, and Reverse CAGR when you know the target and want the required return.

CAGR assumes one starting value and one ending value over time. XIRR uses multiple cashflows with exact dates (SIPs, top-ups, withdrawals), so it better reflects mutual fund and portfolio reality.

Not for true SIP performance because SIPs involve many purchase dates. Use XIRR for accuracy. CAGR is fine for a simplified comparison (single buy vs single sell).

Differences come from assumptions: contribution timing (start vs end of month), compounding frequency (monthly vs yearly), rounding, step-up handling, and whether inflation/taxes/charges are included.

Yes. If you invest at the start of each month, that contribution gets one extra month of compounding compared to end-of-month investing—so final corpus is slightly higher for the same SIP and return.

Use conservative assumptions and test multiple scenarios. A practical approach is to model a base case and a lower-return case. Your best assumption depends on time horizon, asset mix, and how consistently you can invest.

Inflation reduces purchasing power. A simple estimate for real return is: Real ≈ (1+Nominal)/(1+Inflation) − 1. Planning in real terms helps you avoid underestimating future expenses and goals.

Step-up SIP increases your SIP amount every year (or periodically). This often matches salary growth and significantly improves the chance of reaching goals without needing an unrealistically high return.

Over long horizons, step-ups can add a large portion of the final corpus because later contributions become much bigger. If you can afford it, step-up is often a smarter lever than chasing higher returns.

It describes how often returns are applied (monthly, quarterly, yearly). Many investment projections assume monthly compounding for SIP because contributions happen monthly, but some tools approximate yearly compounding—changing results slightly.

Present Value converts a future amount into what it’s worth today at a required return/discount rate. It’s useful for comparing “future price claims” (property, business, deal offers) to a fair price today.

Future Value estimates what your investment may grow into after compounding over time. FV helps you see how today’s savings/SIP may translate into a future corpus if returns and time work in your favor.

Use Reverse CAGR when you know the starting value and target value (or target return) and want to compute the required CAGR. It’s great for sanity-checking whether a goal is realistic.

A common formula is: =(Final/Initial)^(1/Years)-1. If you want a percentage, format the cell as % or multiply by 100.

Use =XIRR(values, dates) where investments are negative and withdrawals/current value are positive. Make sure dates match transaction dates and the final value is included as a positive cashflow.

Usually due to missing cashflows, wrong signs (investment should be negative), wrong dates, or excluding the current portfolio value as a final positive cashflow. Even small date mistakes can move XIRR noticeably.

For realistic planning, it helps to be conservative. Expense ratio is already reflected in mutual fund NAV returns, but taxes depend on holding period and rules. If you’re planning a goal, consider buffers rather than overly precise tax math.

Yes for estimating required savings, target corpus, and scenario ranges. For retirement, it’s wise to consider inflation, step-ups, multiple return scenarios, and a safety margin rather than one “perfect” number.

Invested amount is what you put in. Estimated returns are the growth generated by compounding. The final value (corpus) is invested amount + returns (subject to assumptions).

Compounding is exponential over time. A 1–2% change in assumed return can create a large difference in long-term outcomes, especially beyond 7–10 years.

Yes. For RD/FD-like planning, use the calculator that matches your contribution pattern (monthly for RD, one-time for FD). Make sure compounding frequency and tenure match how the product works.

SIP reduces timing risk by spreading purchases. Lumpsum can work well when you have cash ready and a long horizon, but it may feel more volatile short-term. Many investors mix both depending on cashflow.

No. Outputs are projections based on assumptions. Use calculators to compare options and plan ranges—not as guarantees. Recheck annually as markets and income change.
