Arthavi vs Excel: Why Your Portfolio Spreadsheet Is Costing You Money (2026)

Excel gave you control. But as your portfolio grew, it quietly became a source of errors, outdated prices, and hidden risk. Here's a detailed breakdown of what Excel gets right, where it fails, and what serious Indian investors are switching to.

Why Investors Start With Excel

Excel is familiar, flexible, and free. For someone with 2–3 mutual fund SIPs and one stock holding, a basic spreadsheet works fine. You can log your purchase prices, NAVs, and calculate rough returns without any app. Many experienced investors built detailed trackers over years with complex formulas for XIRR, portfolio allocation, and gains by fund category.

There is nothing wrong with this — until the cracks start showing.

Where Excel Breaks Down for Indian Investors

The moment your portfolio grows to 10+ funds, multi-broker stocks, and monthly SIPs, Excel starts working against you:

• NAV updates are manual: You must update every fund's price by hand, usually with GOOGLEFINANCE or manual copy-paste. Miss a week and your entire portfolio valuation is wrong.
• XIRR is frequently mis-implemented: Most Excel XIRR formulas omit transactions, use the wrong sign convention, or miss the current value as a final cash flow. A wrong XIRR can differ from the real value by 5–15%.
• Corporate actions are ignored: Stock splits, bonuses, and mutual fund dividend reinvestments must be manually updated. Most Excel trackers simply don't account for these.
• No real-time alerts: Excel cannot tell you when your portfolio drops 5% in a day, when a fund underperforms its benchmark, or when your asset allocation drifts.
• No AI analysis: Excel can't answer "Is my portfolio over-exposed to banking?" or "What is my XIRR if I exclude my US stock ETFs?"

The Hidden Time Cost

Indian investors spend an average of 2–4 hours per month maintaining a detailed Excel portfolio tracker. Over a year, that's a full working week spent on data entry, not decision-making. Arthavi reduces this to near-zero — your investment statement automatically populates all mutual fund transactions, and stocks can be bulk-imported from broker CSVs.

Side-by-Side Comparison

When Excel Still Makes Sense

To be fair, Excel isn't always wrong. If you want granular, custom analyses that no app supports — like modelling specific withdrawal scenarios, building your own scoring model, or doing tax optimization analysis — Excel gives you that control. Many serious investors use Arthavi as their live tracker and a separate spreadsheet for one-time modelling exercises.

But for day-to-day portfolio monitoring, return calculation, and staying on top of your wealth — a dedicated tracker built for Indian markets is objectively better.

How to Migrate from Excel to Arthavi in 10 Minutes

1. Mutual Funds: Download your Investment Statement (CAS) from CAMS or KFintech. Import it into Arthavi. Done — all transactions load automatically.
2. Stocks: Export your holdings CSV from Zerodha Console, Groww, or Angel One. Add stocks manually using Arthavi's search, or bulk add via the holdings import feature.
3. Verify: Cross-check your total portfolio value in Arthavi against your Excel. They should match within rounding differences on NAV dates.
