Weekly SIP Calculator
The Weekly SIP Calculator uses 52-week compounding to give you the most accurate projection of a weekly systematic investment plan — enter your weekly investment amount, expected annual return, and investment period to see your total value at maturity, total amount invested, and estimated returns recalculate live as you adjust the sliders. The donut chart splits your final corpus between capital and returns, and the year-wise table shows how your weekly SIP builds at every annual checkpoint across your full investment horizon.

What is a Weekly SIP Calculator?
A weekly SIP calculator projects the maturity value of a systematic investment plan where you invest a fixed amount once every week — 52 times per year — instead of the standard monthly cadence. This weekly systematic investment plan calculator applies the Future Value of Annuity Due formula at a weekly frequency, using a weekly rate of return (annual return ÷ 52) across your chosen investment period. You get your projected total value at maturity, total amount invested, and estimated returns — all driven by weekly compounding, which is more frequent than monthly but less than daily.
A weekly SIP is suited to investors who receive weekly income — freelancers, commission-based earners, or those who find it easier to discipline themselves around a weekly transfer rather than a larger monthly one. It also suits anyone already building wealth through a systematic investment plan and wants to explore whether adding a mid-week contribution frequency makes a meaningful difference to the final corpus.

Weekly SIP Returns Formula
The weekly SIP returns calculation uses the standard annuity due formula adapted for 52 periods per year:
M = P × [(1 + r)ⁿ − 1] / r × (1 + r)
- P = Weekly SIP amount (₹)
- r = Weekly return rate = Annual return ÷ 52 ÷ 100
- n = Total weeks = Years × 52
Example: ₹500/week for 10 years at 12% annual return → r ≈ 0.002308, n = 520. Maturity value ≈ ₹12.0 lakh on ₹2.6 lakh invested. That is equivalent to roughly ₹2,167/month — and the weekly frequency means 52 cost-averaging points per year versus just 12 for a monthly SIP, which reduces the impact of short-term market volatility on your average purchase price. Also explore the monthly sip calculator for a related calculation.
Weekly SIP vs Monthly SIP
For the same annual invested amount, a weekly systematic investment plan produces a slightly higher corpus than a monthly SIP. The compounding advantage of 52 periods versus 12 is real but modest — approximately 0.2–0.4% additional corpus over 10 years. The more significant difference is the rupee cost averaging quality: 52 NAV data points per year mean your average unit cost is closer to the true annual average NAV, reducing the risk of accidentally entering at a weekly high. Here is a side-by-side comparison at 12% annual return for 10 years:
| Weekly SIP | Annual invested | Weekly corpus (10 yr) | Monthly equivalent corpus (10 yr) |
|---|---|---|---|
| ₹500/week | ₹26,000 | ₹12.0 lakh | ₹11.8 lakh (₹2,167/month) |
| ₹1,000/week | ₹52,000 | ₹24.0 lakh | ₹23.7 lakh (₹4,333/month) |
If your mutual fund platform supports weekly SIPs, the marginal return advantage combined with tighter cost averaging makes it a reasonable frequency for your systematic investment plan — especially if weekly budgeting aligns better with how you manage cash flow than a larger monthly deduction would.
Frequently Asked Questions
How does a weekly SIP work?
In a weekly systematic investment plan, a fixed amount is automatically debited from your bank account and invested in your chosen mutual fund once every week — 52 times per year. Each weekly instalment purchases units at that week's NAV, giving you 52 cost-averaging data points annually. The weekly SIP calculator uses a weekly compounding rate (annual return ÷ 52) to project the maturity corpus, which is slightly higher than monthly compounding on the same annual invested amount.
Is weekly SIP available in India?
Yes, many mutual fund platforms in India offer weekly SIP options alongside daily, monthly, and quarterly frequencies. Platforms such as Groww, Zerodha Coin, Paytm Money, MFU (MF Utilities), and several direct AMC websites allow weekly SIP registration. Minimum weekly SIP amounts typically start at ₹100–₹500. Check your specific platform for availability, as not all fund houses support weekly frequency for every scheme.
Does weekly SIP give better returns than monthly SIP?
Yes, marginally. A weekly systematic investment plan produces a slightly higher corpus than a monthly SIP on the same annual invested amount because more frequent compounding (52 periods vs 12) and tighter rupee cost averaging both work in your favour. The return difference is small — around 0.2–0.4% more corpus over 10 years — but the cost-averaging quality is meaningfully better, as your average purchase NAV more closely tracks the actual annual average NAV rather than just 12 sample points.
What is the minimum weekly SIP amount?
Minimum weekly SIP amounts in India vary by platform and fund house. Most platforms that support weekly SIPs allow amounts starting from ₹100 per week, with some accepting ₹500 as the minimum. At ₹500/week, your annual invested amount is ₹26,000 — equivalent to roughly ₹2,167/month. Before starting a weekly SIP, verify the minimum amount and whether the platform processes units at daily NAV or aggregates weekly instructions into a single weekly transaction.
