How the Weekly SIP Calculator works
A weekly SIP invests every week — 52 times a year. It suits people paid weekly or those who want to spread purchases more finely than monthly without the statement clutter of daily SIPs.
The calculator compounds weekly and compares with a monthly SIP of 52 ÷ 12 × the weekly amount, so both invest the same money each year.
FV = A × [ ((1+i)^N − 1) / i ] × (1+i)
- A
- weekly instalment
- i
- annual return ÷ 52
- N
- years × 52
Worked example
- Weekly investment: ₹1,000
- Expected return (p.a.): 12%
- Time period: 10 Yr
₹1,000 a week is ₹52,000 a year. At 12% for 10 years it grows to about ₹10.1 lakh, versus ₹10.05 lakh for the equivalent ₹4,333 monthly SIP — a negligible gap.
