About Us

Free, open tools to help you make better investment decisions using real data — not assumptions.

fundsipcalculator.com was built to solve a simple problem: most SIP calculators use assumed return rates (like "assume 12% annual returns"), but real mutual fund performance varies widely across funds and time periods. We use actual historical NAV data from Indian mutual funds sourced from AMFI and BSE to show you what your SIP or lumpsum investment would have really returned in any fund, over any time period.

What started as a simple idea — "what if my SIP calculator used real data instead of guesses?" — has grown into a comprehensive suite of financial planning tools used by thousands of Indian investors every month. Our tools help people make informed decisions about SIP investing, FIRE planning, loan comparisons, and understanding the true cost of delaying their investments.

Our Story

fundsipcalculator.com started as a side project by a group of Indian finance enthusiasts who were frustrated with the investment calculators available online. Every SIP calculator we found either used a flat 12% assumed return (completely unrealistic) or required creating an account and sharing personal data. We wanted something better — a tool that used real mutual fund NAV data, respected user privacy, and was completely free.

The first version launched with a single feature: enter a fund name, an amount, and a date range, and see exactly what your SIP would have returned based on real historical NAV data. The response was immediate and encouraging — thousands of users in the first month, with messages asking for more features, more funds, and more calculators. Today, what started as a single-page tool has grown into a comprehensive suite of financial planning calculators serving over 50,000 Indian investors every month.

We remain committed to the original vision: real data, no sign-ups, no hidden fees, and complete transparency in every calculation. We are funded entirely through non-intrusive advertisements that keep the site free for everyone.

Our Mission

Our mission is to democratise financial planning for Indian investors. We believe that everyone deserves access to accurate, transparent, and free financial tools — regardless of their account balance, technical knowledge, or investment experience. By removing the barriers of expensive financial advisors, complex software, and opaque calculations, we help investors take control of their financial future.

Content Review Process

Every piece of content on fundsipcalculator.com — from blog articles to fund analyses to FAQ answers — goes through a structured review process before publication:

1. Research & Draft: Our writers research the topic using authoritative sources including AMFI reports, SEBI circulars, Income Tax Department publications, and RBI databases. The first draft is written with a focus on accuracy, clarity, and practical value for Indian investors.
2. Fact-Checking: Every financial figure, tax rate, fund statistic, and regulatory reference is verified against official sources. We do not publish unverified numbers or assume data points.
3. Editorial Review: A senior editor reviews the draft for clarity, structure, and alignment with our editorial standards. The review ensures the content is accessible to beginners while still valuable for experienced investors.
4. Technical Review: For fund-specific content, the analysis is reviewed against actual fund data (NAV history, portfolio holdings, category benchmarks) to ensure accuracy.
5. Publication & Review Date: Every published piece carries a "Last reviewed" date. We review content at least annually, or sooner if there are significant regulatory changes (such as budget announcements, SEBI re-categorisation, or tax rule changes).

This process ensures that our readers can trust the information they find on our site. If you spot an error, please contact us — we correct factual errors promptly and transparently.

Data Sources and Methodology

All calculators on fundsipcalculator.com use a transparent, data-driven methodology to ensure accuracy and reliability. Here is how our data is sourced and processed:

• Mutual Fund NAV Data: Historical Net Asset Value data is sourced from the Association of Mutual Funds in India (AMFI) and BSE India public APIs. We maintain a database of Indian mutual fund schemes with daily NAV history going back to the fund's inception. Data is updated regularly to include new schemes and the latest available NAV values.
• Inflation and Economic Data: Historical inflation rates, RBI policy rates, and economic indicators used in our calculators (FIRE calculator, Cost of Delay) are sourced from the Reserve Bank of India (RBI) database and the Ministry of Statistics and Programme Implementation (MOSPI). Default values are based on 10-year historical averages for Indian markets.
• Loan and EMI Calculations: Interest rate benchmarks for our SIP vs EMI calculator are based on current lending rates published by the Reserve Bank of India and major Indian banks. Personal loan, home loan, car loan, and education loan rate ranges reflect publicly available data from leading financial institutions.
• Calculation Methodology: All calculations are performed client-side in your browser using standard financial formulas: future value of annuity for SIP calculations, XIRR for annualised returns, PMT for EMI calculations, and time-adjusted projections for FIRE planning. We do not use proprietary or black-box algorithms. Every formula is transparent and verifiable.

While we strive for accuracy and timeliness, NAV data may occasionally have gaps or delays. Fund schemes and categories may change over time. We recommend cross-referencing critical investment decisions with official sources including the respective AMC websites, AMFI, and SEBI.

Accuracy and Data Freshness Disclaimer

The financial data used across this website is sourced from publicly available APIs and databases, including AMFI, BSE, and RBI. While we update our data regularly, there may be inherent delays in data availability from these sources. NAV data for mutual funds is typically updated daily but may be delayed by 1-2 business days during periods of high market activity or technical outages.

Users should note that:

• All calculations are based on historical data and should not be considered as guarantees of future performance.
• Expense ratios, exit loads, and other fund-specific charges are not factored into calculator results unless explicitly stated.
• Tax implications (LTCG, STCG, dividend distribution tax) are not automatically included in calculations.
• Users should verify critical numbers with a SEBI-registered financial advisor before making investment decisions.

Last updated: August 2026. Data freshness: NAV data updated regularly from AMFI and BSE public sources. The exact number of schemes covered may vary as funds are launched, merged, or closed.

Our Principles

• No sign-ups — Use all tools instantly, no account needed
• Transparent calculations — Real data, no hidden assumptions or black-box formulas
• Privacy-focused — No personal data collection; only anonymous, aggregate analytics (Google Analytics) to improve the site
• Ad-supported but not ad-bloated — We display advertisements to keep the site free, but ads are placed thoughtfully and do not interfere with calculator usability

Editorial Policy

All content on fundsipcalculator.com is produced by our editorial team with the goal of providing accurate, actionable, and up-to-date financial information for Indian investors. Our editorial standards ensure that every article and calculator meets the following criteria:

• Fact-checked against official sources — All fund data, expense ratios, and returns are sourced from AMFI, BSE, and individual AMC websites. Tax rules reference the Income Tax Act and CBDT circulars.
• Regularly reviewed — Every blog post displays a "Last reviewed" date. Posts are reviewed at least annually to ensure accuracy, especially when SEBI regulations or tax laws change.
• No paid placements — We do not accept payment from fund houses to feature their funds. Fund pages include all major schemes in each category, not just those that pay us.
• Clear separation of fact and opinion — Data-driven analysis is clearly distinguished from editorial commentary. Where we express an opinion (e.g., "index funds are best for beginners"), we explain the reasoning.
• Corrections policy — If you spot an error, please contact us. We correct factual errors promptly and note the correction date.
