Daily SIP Calculator 2026: Calculate Daily SIP Returns

What is a Daily Systematic Investment Plan (SIP)?

A Daily Systematic Investment Plan (SIP) is a structured investment strategy that allows individuals to invest a fixed sum of money into mutual funds every single day, rather than making monthly or quarterly contributions. It is a highly granular wealth accumulation method designed to capture market movements on a daily basis.

Traditionally, SIPs are set up as monthly auto-debits. While monthly SIPs are excellent, they buy units on one specific day of the month, exposing the investor to whatever market volatility prevails on that day. A daily SIP spreads this risk across all trading days of the month. By investing daily, you smooth out the purchase price of mutual fund units to an extreme degree. This is a practice known as hyper-diversification of entry price, and it has gained massive popularity in India through fintech platforms like Zerodha, Dhan, Groww, and Paytm.

How does the Daily SIP Calculator Work? The Mathematics of Daily Compounding

The Daily SIP Calculator uses the standard compound interest model adapted for daily cash inflows. Because deposits occur daily, the calculation employs daily interest rates and daily compounding periods.

The generalized Future Value formula for an annuity due (since deposits are made at the start of each day) is:

Step-by-Step Mathematical Example:

Suppose you set up a Daily SIP of **₹100 per day** at an expected return rate of **12% per annum** for a period of **10 years**. Here is how we calculate the final value:

1. Calculate daily interest rate (i):
   i = 12 ÷ 365 ÷ 100 ≈ 0.000328767 (0.0328767% per day)
2. Compute total compounding days (n):
   n = 10 years × 365 days = 3650 days
3. Solve the exponential growth factor:
   (1 + i)^n = (1.000328767)^3650 ≈ 3.319389
4. Calculate FV numerator:
   (1 + i)^n - 1 = 3.319389 - 1 = 2.319389
5. Apply the Annuity formula:
   FV = 100 × (2.319389 ÷ 0.000328767) × (1.000328767) ≈ ₹705,671

Over 10 years, your cumulative investment is **₹3,65,000** (₹100 × 365 days × 10 years), and your final portfolio grows to **₹7,05,671**, yielding returns of **₹3,40,671**.

Daily SIP vs. Monthly SIP: The Analytical Comparison

Many investors debate whether a daily SIP offers any real performance advantage over a standard monthly SIP:

• Rupee Cost Averaging Efficiency:Daily SIPs offer the ultimate averaging effect. If the market undergoes a sharp intraday correction, a daily SIP will automatically purchase units at that lower NAV. Monthly SIPs, however, can miss short-lived dips if they occur mid-month.
• Compounding Power:Mathematically, compounding daily instead of monthly produces slightly higher growth on identical interest structures, though the difference is very marginal over long horizons.
• Cash Flow Alignment:For daily income earners—such as retail shop owners, cab drivers, freelancers, and commission agents—daily SIPs align perfectly with their daily cash inflows, making it much easier to save than accumulating a large sum to pay at the end of the month.

Critical Tax Implications of Daily SIP in India

While daily SIPs are outstanding for discipline, they introduce unique administrative and tax-reporting complexities under the Indian Income Tax Act. It is crucial to understand these rules before investing:

To qualify for **Long-Term Capital Gains (LTCG)** (taxed at 12.5% on gains exceeding ₹1.25 Lakh per financial year), each unit must have been held for more than **365 days (1 year)**.

If you start a daily SIP and decide to redeem your entire investment exactly 3 years later:

• Units bought in the first 2 years will have completed the 1-year holding period, qualifying for **LTCG**.
• However, units bought during the final 365 days of your SIP will NOT have completed the 1-year holding period. Redemptions on these units will trigger **Short-Term Capital Gains (STCG)**, which is taxed at a flat rate of **20%**.
• This requires keeping a highly detailed ledger of transactions, though modern brokers (like Zerodha Console, Groww, or CAMS reports) compile capital gains reports automatically.
