SIP basics

How SIP investing works

Regular investing

SIP invests a fixed amount on a schedule, often monthly, instead of investing everything at once.

Rupee or cost averaging

Regular investing can average purchase prices over time, though it does not remove market risk.

Time in market

Longer investment periods give contributions more time to compound, but outcomes still depend on returns.

Compounding

Returns can earn further returns over time, which is why long-term SIP growth can accelerate.

Comparison

SIP vs lump sum investing

SIP investing

Regular contributions

SIP spreads investments over time and can be easier for monthly budgeting and disciplined investing.

Lump sum investing

One-time investment

Lump sum investing puts more money to work immediately, but timing risk may be higher if markets move sharply.

Step-up

Step-up SIP and contribution growth

Annual increase

A step-up SIP increases the monthly investment by a chosen percentage each year.

Income alignment

Step-ups can help align investing with expected income growth or savings capacity.

Long-term impact

Even small yearly increases may materially affect maturity value over long periods.

Formula

SIP formula explanation

Monthly SIP future value

FV = P × [((1 + r)^n − 1) / r] × (1 + r)

P is the monthly SIP amount, r is the monthly return rate, and n is the number of months.

Invested amount

Invested Amount = Monthly SIP × Number of Months

With step-up SIP, invested amount is the sum of all monthly investments over time.

Estimated returns

Estimated Returns = Maturity Value − Invested Amount

Estimated returns show the growth above total invested contributions.
