SIP guide
Is your SIP stuck at 0% return? Learn how units and NAV work through a simple story with real numbers, why this is the best buying phase, and how to check if your fund is right.
You've invested every single month for two years. You open your statement expecting some growth, and the return column says 0%. Twenty-four instalments, and nothing to show for it.
This is exactly the point where many investors stop their SIP. It feels like the money is stuck.
But here's what the statement doesn't show you clearly: while your returns were flat, your units were quietly piling up at low prices. And units are what eventually create wealth.
When you invest in a mutual fund, you're not really buying "rupees of returns". You're buying units. The price of one unit is called the NAV (Net Asset Value).
Think of it like buying gold every month with a fixed budget of ₹10,000:
A SIP works the same way. When the NAV falls, your fixed instalment automatically buys more units.
The value you see in your statement is simply: total units × today's NAV. So when the market is down, the value looks weak, even though the number of units you own keeps growing.
Amit and Vikram, two friends from Surat, started a ₹10,000 monthly SIP in the same fund on the same day. The NAV was ₹100.
The first year was rough. The market kept sliding, and by month 12 the NAV had dropped to ₹60. They had each put in ₹1,20,000, but their statements showed only about ₹92,000.
Vikram panicked. "I'm losing money every month," he said, and stopped his SIP. He kept the units he already had, but invested nothing more.
Amit was worried too, but before deciding anything he called the mutual fund distributor who managed his investments. The advice he got was simple: "Don't count rupees right now. Count units." Amit kept his SIP running.
The second year brought only a mild recovery. By month 24, the NAV had climbed to just ₹71.5, still well below where they started. Amit had invested ₹2,40,000 and his portfolio was worth about ₹2,39,900. Practically 0% return.
Vikram couldn't resist: "Two years of discipline, and you're still at zero!" What he didn't see was the one thing Amit had gained that no return column shows.
Over 24 months, Amit collected 3,355 units. Had the NAV stayed at ₹100 throughout, the same ₹2,40,000 would have bought only 2,400 units. The falling market gave him roughly 955 extra units.
| Month | NAV (₹) | Units bought that month | Total units | Total invested (₹) | Portfolio value (₹) |
|---|---|---|---|---|---|
| 1 | 100.0 | 100.0 | 100 | 10,000 | 10,000 |
| 6 | 81.8 | 122.2 | 663 | 60,000 | 54,254 |
| 12 | 60.0 | 166.7 | 1,539 | 1,20,000 | 92,319 |
| 18 | 65.8 | 152.1 | 2,486 | 1,80,000 | 1,63,476 |
| 24 | 71.5 | 139.9 | 3,355 | 2,40,000 | 2,39,888 |
Notice when Amit bought the most units: in month 12, when things looked worst, his ₹10,000 bought 166.7 units instead of 100. The very moment Vikram walked away was the best buying opportunity of the entire journey.
These figures are an illustration to explain the concept and do not represent any specific fund.
In the third year the market recovered, and by month 36 the NAV was back at ₹100. Not a boom, just a return to where it all began.
| Amit (continued SIP) | Vikram (stopped at month 12) | |
|---|---|---|
| Total invested | ₹3,60,000 | ₹1,20,000 |
| Total units | 4,748 | 1,539 |
| Value at month 36 (NAV ₹100) | ₹4,74,785 | ₹1,53,864 |
| Profit | ₹1,14,785 | ₹33,864 |
| Annualised return (XIRR, approx.) | 19% | 10% |
The NAV only came back to its starting point, yet Amit earned roughly 19% a year. That return came entirely from the cheap units he kept buying while his statement showed zero.
Those "0% years" were not wasted. They were the accumulation phase. Returns tend to show up all at once, when the market recovers.
Amit's story works only because he was in a good fund. A flat return can have two very different causes: a weak market or a weak fund. Patience pays in the first case. In the second, patience just costs you time.
Some investors end up in funds that may not deliver good returns even in the future. Common warning signs:
In such cases, continuing the SIP will still add units, but there's no assurance those units will grow in value. Accumulating more units of the wrong fund is not an advantage.
Don't decide whether to stop or continue your SIP based on emotion. Decide based on a review. Have your complete portfolio checked by a qualified, registered professional. A good review looks at:
In short: the right fund + patience = Amit's result. The wrong fund + patience = lost time.
Do:
Don't:
A 0% return on your SIP isn't failure. It's the buying season. Count units, not rupees. When the market turns, those units become your returns.
Not on the 0% figure alone. First check whether the cause is the whole market or your fund. When the market is down, your SIP buys more units with the same amount, and those units are what deliver the return when the market recovers.
When you invest in a mutual fund you buy units, not rupees of returns. Each month your SIP amount is converted into units at that day's NAV. Your investment value is total units × today's NAV.
NAV (Net Asset Value) is the price of one unit of a fund, worked out at the end of every business day. When the NAV falls, the same SIP amount buys more units.
Your CAS (Consolidated Account Statement) or the fund house statement lists "Units" or "Balance Units" against every fund. If that number rises every month, your SIP is doing its job.
Compare your fund with other funds in the same category and with its benchmark. If the whole category is down, it is the market. If other funds are doing well and yours has lagged for years, the fund needs a review.
Give equity funds at least 5 to 7 years. Judging them on one or two years of returns, as Vikram did, usually means stopping just when units are cheapest.
