An STP (Systematic Transfer Plan) automatically moves a fixed amount from one mutual fund scheme into another at regular intervals, typically from a low-risk liquid or debt fund into an equity fund. In effect, it lets you feed a lump sum into the market in slices instead of investing it all on one day, spreading out the price you pay across weeks or months.
The money you have not yet moved does not sit idle. It stays in the source fund, usually a liquid or debt fund, and keeps earning there while it waits its turn.
How does an STP work?
You start with money already parked in one scheme (the source) and instruct the fund house to transfer a set amount, on a set frequency, into a target scheme. Both schemes must belong to the same asset management company. Transfers can run daily, weekly, fortnightly, or monthly until the source runs down.
Here is the shape of a simple monthly STP, using illustrative figures.
How an STP is set up (illustrative)
While the ₹5,00,000 still waiting is held in the liquid or debt fund, it earns that fund's return rather than nothing. That is the advantage over leaving a lump sum in a savings account and investing it by hand each month.
STP vs SIP: what is the difference?
They look similar (both invest a fixed amount on a schedule), but the source of the money is different. An SIP pulls money from your bank account into a fund. An STP moves money that is already inside a mutual fund into another scheme of the same house.
So an SIP is how you build a corpus out of monthly income. An STP is how you redeploy a lump sum you already have, whether a bonus, a maturity payout or the sale of a property, without dumping it into equity in one shot.
What are the types of STP?
- Fixed STP. A fixed amount moves across each period: the plain vanilla version, and the one most people use.
- Capital appreciation STP. Only the gains earned in the source fund are transferred, leaving your original capital intact in the low-risk fund. This moves smaller, variable amounts and keeps the principal protected.
What each transfer costs: tax and exit load
This is the part that surprises people. Each transfer is not a free internal shuffle. It is a redemption from the source fund and a fresh purchase in the target, and that has two consequences.
Because the source is usually a debt or liquid fund, the gains are typically small, so the tax is rarely large. But it is real, and it is why an STP is not just money walking from one pocket to another.
Who is an STP for?
An STP suits someone who has received a large sum at once and is wary of investing all of it at a single market level. Instead of guessing whether today is a high or a low, you let the transfers average your entry across the schedule. The trade-off is plain: if markets rise steadily through the transfer window, moving in gradually will lag investing the whole amount up front. If markets fall or swing, the staggered entry cushions you.
It is a tool for managing the timing of a lump sum, not a promise of a better return. The right choice between a full lump sum and an STP depends on your comfort with a single-day entry and how long the money can wait, not on any forecast.

Before setting one up, settle the prior question: how much of this lump sum are you willing to commit at a single day's price? Your answer decides the schedule, the frequency and the source fund. The STP itself is just the plumbing that carries the decision out.
