How a digital gold SIP works, one debit at a time
The technique
The debit is rupees; the gold is whatever is left after tax
People picture a gold SIP as Rs 2,000 of gold a month. It is Rs 2,000 of money a month, from which GST is taken first, and only the remainder is converted to grams at that day's buy rate. Reading it as rupees of gold overstates what you own by the tax on every instalment.
You pick an amount and a schedule, usually daily, weekly or monthly depending on the provider, and approve a mandate on your bank account. On each due date the amount is debited. GST on gold, 3 percent at the time of writing, is applied to the purchase, and the rest buys grams at that day's buy rate, which the provider sets from the market price. The grams are credited to your account in fractions, typically to four decimal places, and the metal is held for you by a custodian in a vault.
Most providers take the GST out of the amount you choose; some add it to the amount. The difference matters when you reconcile your bank statement against your gold balance. Here is one illustrative Rs 2,000 debit on a day when the buy rate is Rs 10,000 a gram, and what the same gold would fetch if you sold it that afternoon.
- Debited from your bank account
- Rs 2,000
- GST inside the debit
- Rs 58.25
- Gold value bought
- Rs 1,941.75
- Grams credited at Rs 10,000 a gram
- 0.1942 g
- Sell rate the same day
- Rs 9,750 a gram
- What those grams fetch if sold at once
- Rs 1,893.20
- Loss on day one
- Rs 106.80, or 5.34%
Buy rate, sell rate and the gap between them are illustrative. The sell rate here is set 2.5 percent below the buy rate; your provider shows both rates, and the gap varies by provider and by day.
- If the provider adds GST to the amount instead, a Rs 2,000 SIP debits Rs 2,060 a month: Rs 60 of GST per debit, Rs 720 over twelve months, Rs 24,720 in total. Check which way yours works before comparing it with anything
- The day-one loss is not a fee you can negotiate away. It is the GST plus the buy-sell gap, and the price has to rise 5.64 percent before any single instalment is worth what you paid for it
- Many providers let an SIP start from as little as Rs 10. A small minimum makes the habit easy to begin; it does not make each rupee cheaper to buy
