Is a SIP exactly the same as dollar-cost averaging?

Yes. They are two names for investing a fixed amount at regular intervals. The projection maths is identical; only the local terminology, currency and tax rules differ.

Why do people say SIP is only for mutual funds?

In India, SIPs are most commonly set up into mutual funds, so the term picked up that association. The strategy itself works with any regularly-purchased investment — index funds, ETFs or shares — which is why the Western term 'dollar-cost averaging' is broader.

Which term should I use?

Use whichever your broker and country use — they all describe the same monthly-investing habit. When reading foreign finance content, just mentally translate: SIP = DCA = pound-cost averaging = PAC = RSP.

SIP vs dollar-cost averaging: same strategy, different name

By GrowThenDraw Editorial Team · Updated July 4, 2026 · 5 min read · Editorial policy

If you learned to invest in India you call it a SIP. In America it's dollar-cost averaging. In Britain, pound-cost averaging. In Canada, a pre-authorised contribution. Four names, one idea — and a lot of needless confusion when people move countries or read foreign finance articles.

This guide untangles the vocabulary so you can read any of it without second-guessing, and explains why the underlying maths is genuinely identical everywhere.

The one strategy behind all the names

Every one of these terms means the same behaviour: investing a fixed amount of money at regular intervals — usually monthly — regardless of what the market is doing that month. You buy more units when prices are low and fewer when they're high, which smooths out your average purchase price over time.

The vocabulary, decoded

SIP (Systematic Investment Plan) — the standard term in India and much of Asia, usually referring to automatic monthly investments into mutual funds.
Dollar-cost averaging (DCA) — the American term for the identical strategy, whether into index funds, ETFs or individual shares.
Pound-cost averaging — simply the British name for dollar-cost averaging.
Pre-authorised contribution (PAC) — what Canadian brokers call the automatic monthly purchase.
Regular savings plan (RSP) — the phrasing common in Singapore.

A word of warning for UK readers

In the United Kingdom the letters 'SIP' officially mean something completely different — a Share Incentive Plan, an employee share scheme — and 'SIPP' is a personal pension. If you search 'SIP' from the UK you'll mostly find those. For the monthly-investing strategy, search 'pound-cost averaging' or 'regular investing' instead.

Why the maths is identical

Because the mechanic is the same — fixed amount, fixed interval, compounding returns — the formula that projects your final corpus doesn't care which word you use. A calculator built for one works perfectly for all of them; only the currency and the tax treatment change from country to country.

That tax treatment is the part worth localising. The growth maths is universal, but what you keep after selling depends entirely on where you live — which is why it pays to use a calculator built for your specific country rather than a generic one.
