What is a daily SIP calculator?

A daily SIP calculator projects the future value of SIPs where you invest a fixed amount every day instead of every month. It uses the compound interest formula with daily compounding: FV = P × [((1 + i)^n - 1) / i] × (1 + i), where i is the daily rate and n is the number of days.

Is daily SIP better than monthly SIP?

Daily SIPs can offer marginally better returns due to more frequent compounding and rupee-cost averaging across more market days. However, the difference is usually small (0.1-0.5% annually). Most Indian mutual funds only offer monthly SIPs; daily SIPs are rare and may have higher transaction costs.

Do Indian mutual funds offer daily SIPs?

Most Indian mutual funds offer only monthly SIPs. A few fund houses offer weekly or fortnightly SIPs. Daily SIPs are very rare. For most investors, a monthly SIP is simpler and equally effective. Use our daily SIP calculator to compare scenarios.

How is daily SIP return calculated?

Daily SIP returns are calculated using the formula: FV = P × [((1 + r/365)^n - 1) / (r/365)] × (1 + r/365), where P is daily investment, r is annual return rate, and n is total number of days. Our daily SIP calculator handles this automatically.

What is the equivalent monthly SIP for ₹500 daily?

A ₹500 daily SIP is approximately equivalent to a ₹15,000 monthly SIP (₹500 × 30 days). Use our daily SIP calculator above to see exact projections and compare with monthly SIP scenarios.

About the Daily SIP Calculator

The Daily SIP Calculator on S₹P Calculator Online is a specialized tool that projects the future value of Systematic Investment Plans where contributions are made daily rather than monthly. While monthly SIPs are the norm in India, daily SIPs offer theoretical advantages in terms of more frequent compounding and rupee-cost averaging — and this calculator helps you quantify those advantages.

The calculator uses the compound interest formula adapted for daily contributions: FV = P × [((1 + i)^n - 1) / i] × (1 + i), where P is the daily investment amount, i is the daily interest rate (annual rate ÷ 365 ÷ 100), and n is the total number of days. The result is the maturity value, total invested amount, estimated returns, total days invested, and the equivalent monthly SIP amount for comparison.

Daily SIP vs Monthly SIP — Theoretical Benefits

Daily SIPs offer two main theoretical advantages over monthly SIPs:

More frequent compounding — Daily compounding results in slightly higher effective annual yield compared to monthly compounding. Over long horizons, this can add 0.1-0.5% to annual returns.
Better rupee-cost averaging — With 365 investment points per year instead of 12, you average across more market days, potentially capturing more dips and reducing average purchase cost.

Practical Limitations of Daily SIPs in India

While daily SIPs sound attractive in theory, they face several practical limitations in the Indian context:

Availability — Most Indian mutual fund houses do not offer daily SIPs. Monthly is the standard, with some offering weekly or fortnightly options.
Transaction costs — Daily SIPs may incur higher transaction costs (payment gateway fees, mandate charges) that can offset the marginal compounding benefit.
Operational complexity — Tracking 365 transactions per year per fund is operationally cumbersome for both investors and fund houses.
Auto-debit limits — Bank auto-debit mandates may have daily limits that constrain daily SIP amounts.

For most investors, a monthly SIP is simpler, equally effective, and widely available. However, the daily SIP calculator is useful for understanding the theoretical impact of compounding frequency and for those rare funds that do offer daily SIPs.

When Daily SIPs Might Make Sense

Despite the limitations, daily SIPs can make sense in specific scenarios. Some new-age platforms and robo-advisors offer "round-up" investing — where your daily spare change from purchases is invested in mutual funds. This effectively creates a daily SIP. Also, business owners with daily cash flow (shopkeepers, freelancers with daily payments) may find daily SIPs align better with their income pattern. Finally, the daily SIP calculator is educational — showing how compounding frequency affects long-term wealth.

How to Use the Daily SIP Calculator

Using our daily SIP calculator is straightforward:

Enter your daily investment amount. For example, ₹500 per day.
Set expected annual return rate. 12% for equity mutual funds, 7% for debt funds.
Choose time period in years. Use the slider to select 1 to 40 years.
Review the results. Maturity value, invested amount, estimated returns, total days, and equivalent monthly SIP update instantly.

Daily SIP Calculator Examples

Here are some common scenarios:

₹500/day for 10 years at 12% → Maturity: ₹35.4 lakh (Invested: ₹18.25 lakh)
₹1,000/day for 15 years at 12% → Maturity: ₹1.49 crore (Invested: ₹54.75 lakh)
₹300/day for 20 years at 12% → Maturity: ₹1.62 crore (Invested: ₹21.9 lakh)
₹500/day for 25 years at 12% → Maturity: ₹4.85 crore (Invested: ₹45.6 lakh)

Notice that the equivalent monthly SIP is shown alongside — ₹500/day equals about ₹15,000/month. Comparing the maturity value of ₹500/day vs ₹15,000/month for the same tenure shows the marginal benefit of daily compounding.

Daily SIP vs Monthly SIP — Real Comparison

For a 15-year horizon at 12% returns:

₹1,000/day (₹30,000/month equivalent) → Maturity: ₹1.49 crore
₹30,000/month → Maturity: ₹1.51 crore (using monthly compounding)

Surprisingly, the monthly SIP gives a slightly higher maturity value in this calculation. This is because monthly SIPs invest the full ₹30,000 on day 1 of each month, while daily SIPs spread it across 30 days — meaning the average invested period is shorter for daily SIPs. The compounding frequency advantage of daily SIPs is small and can be offset by the timing difference. For most practical purposes, monthly SIPs are equivalent or better.

Conclusion

The daily SIP calculator is a useful educational tool to understand compounding frequency, but for actual investing, monthly SIPs remain the recommended approach for Indian investors. They are widely available, simple to set up, operationally easy to track, and deliver essentially the same returns as daily SIPs.
