This mutual funds calculator compounds monthly (SIP timing) and annually (lump sums) at the assumed return. Returns are assumed, not promised — use a conservative rate for goals.

Visualizations

Invested vs Gains

Invested54%
Gains46%

Formula

Absolute gain over invested, with geometric annualization for cross-period comparison.

ROI = (Current − Invested) ÷ Invested; CAGR = (End/Start)^(1/yrs) − 1

Variables

SymbolNameUnitDescription
GainAbsolute gaincurrencyCurrent minus invested

Explanation

Total and annualized return on money invested.

Step-by-Step Calculation

Follow each step to understand how the result is calculated from your inputs.

Step 1

Subtract invested from current value.

Gain = Current − Invested
Result: $502,300.00
Step 2

Divide by invested for ROI; annualize geometrically.

ROI = Gain ÷ Invested; CAGR = (End/Start)^(1/yrs) − 1
Result: 83.72% total, 6.27% p.a.
Final Answer
83.72%

Scenario

The mutual fund roi calculator run on the values above, showing the full calculation path rather than only the answer.

Inputs

Total Invested:600000
Current / Maturity Value:1102300
Time Horizon:10

Calculation

1. Subtract invested from current value. → $502,300.00 2. Divide by invested for ROI; annualize geometrically. → 83.72% total, 6.27% p.a.

Result

Total ROI: 83.72%

Interpretation

83.72% total (6.27% p.a.) on $600,000 → $1,102,300.

Understanding Your Result

Your Result: Total ROI: 83.72%

What This Means

Total and annualized return on money invested.

Why It Matters

83.72% total (6.27% p.a.) on $600,000 → $1,102,300.

Professional Interpretation

83.72% total (6.27% p.a.) on $600,000 → $1,102,300.

How this is calculated

Absolute gain over invested, with geometric annualization for cross-period comparison.

What drives the result

Compounding rewards time more than timing. A fixed SIP buys fewer units when prices are high and more when low (rupee-cost averaging), while a lump sum maximizes time in the market. CAGR smooths a lump sum; XIRR correctly handles staged SIP cash flows.

Recommendations

  • •Compare annualized returns, not absolute gains, across periods.
  • •Adjust for expense ratio and tax before ranking funds.

Educational Content

Introduction

Fund growth comes from two engines: the return on money already invested and new contributions (SIP instalments or lump sums) joining the compounding base. Every figure here — corpus, gains, CAGR, XIRR — derives from projecting dated cash flows at an assumed return.

Concept Explanation

Compounding rewards time more than timing. A fixed SIP buys fewer units when prices are high and more when low (rupee-cost averaging), while a lump sum maximizes time in the market. CAGR smooths a lump sum; XIRR correctly handles staged SIP cash flows.

Applications

▸Projecting a SIP or lump sum to a goal corpus
▸Comparing two funds on CAGR or XIRR over identical windows
▸Translating a goal (education, retirement) into a monthly SIP
▸Judging whether a dividend payout or growth option suits you

Benefits

  • •Puts SIP, step-up SIP and lump sum on one comparable maths base
  • •Separates invested, gains and multiple so progress is trackable
  • •Annualizes correctly (CAGR for lump, XIRR for SIP)
  • •Shows the path year by year, not just the endpoint

Limitations

  • •Returns are assumed constant; markets are volatile and sequenced
  • •Expense ratios, taxes and exit loads modeled only where entered
  • •Inflation adjustment shown only in the inflation mode
  • •Past performance does not predict future returns

Best Practices

  • •Automate the SIP and step it up with income
  • •Compare XIRR for SIPs and CAGR for lump sums — never mix them
  • •Revisit assumptions yearly; extend tenure before chasing return
  • •Keep an emergency buffer outside the investment

Common Misconceptions

Myth: A higher return always wins
Truth: A higher assumed return with lower consistency often loses to a steadier compounder after costs and taxes.
Myth: SIP guarantees profits
Truth: SIPs average purchase cost; they do not guarantee positive returns in falling markets.

Practical Tips

  • •Annualize before ranking funds across different periods.

Common Mistakes

Annualizing by simple division
Use geometric CAGR, not gain ÷ years.

Assumptions

This calculator makes the following assumptions to provide estimates:

Single holding period: Interim flows ignored.

Limitations

Be aware of these limitations when using this calculator:

Limitation: Returns are assumed constant; markets are volatile and sequenced
Limitation: Expense ratios, taxes and exit loads modeled only where entered
Limitation: Inflation adjustment shown only in the inflation mode
Limitation: Past performance does not predict future returns

Frequently Asked Questions

Answers to common questions about this calculator.

ROI vs CAGR — which to quote?
ROI for total move; CAGR (annualized) to compare different horizons.
Who uses the mutual fund roi calculator?
It is used by investors comparing mutual fund options, by advisers checking a quote before a client commits, and by planners sizing contributions for a goal. It sits in the Mutual Funds group of the ETFs & Mutual Funds section of Atlascalcs.
How accurate is the mutual fund roi calculator?
Every figure follows directly from the inputs using standard fund mathematics, so it is accurate to the quality of the values you enter. NAV rounding, actual SIP dates and changing expense ratios explain small gaps versus statements.
How current are the returns used here?
The calculator uses the return you enter. Update it to the fund factsheet trailing CAGR/XIRR or your own conservative assumption. Costs and tax slabs follow the conventions in the references.
Does rounding change the results?
Math runs at full precision; display rounds only. AMCs round NAVs to 4 decimals, so expect paise-level differences.
SIP or lump sum — which is better?
Lump sums maximize time invested and win in rising markets; SIPs average cost and enforce discipline. With cash available, staged deployment (STP over 6–12 months) splits the difference.
What should I have ready before investing?
Monthly budget, horizon, expected return grounded in benchmark history, expense ratios, exit-load windows and your tax slab. With those, every figure here ties to a fund document.
