Sovereign Gold Bond (SGB) Returns Calculator

How does this tool turn a gold price into a return?

This tool uses a plain proportion. Grams bought equal the amount invested divided by the purchase price per gram, and the maturity or sale value is those grams times the gold price you enter. The capital gain is that value minus the amount invested, and it can be negative. Nothing is compounded and no price path is simulated; the price you type is the whole price assumption.

How is the interest calculated?

The tool takes 2.5% a year of the amount invested, a rate hard-coded in the file, and multiplies it by the holding years to get total interest. It does not compound that interest, does not split it into half-yearly credits and does not reinvest it. Tax on the interest is the total interest times the slab you choose times 1.04.

When is capital gain tax shown as zero?

When the holding period you enter is 8 years or more. Below 8 years the tool applies 12.5% plus 4% cess to any positive gain, with no distinction between holds under and over a year and no indexation. A loss gives a tax of zero. The 8-year cut-off and the 12.5% rate are figures built into this tool and not read from a live source.

What is the “Approximate XIRR” line?

Despite the name it is a simple annualised figure: ((net maturity value + total interest) ÷ amount invested) raised to 1 ÷ years, minus one. It treats all the interest as arriving at the end and ignores tax on the interest, so it is neither a true XIRR nor an after-tax rate. It does use the value after the capital gain tax.

Are the default prices market data?

No. The purchase price starts at ₹6,000 a gram and the expected gold price at ₹7,500, and they are placeholders that carry no date. A price of 0, which is also what a cleared box becomes, falls back to the same defaults. Enter the issue price on your certificate and the price you want to test, because the tool cannot know either.

What does the tool not model?

It does not check whether a series is open, does not apply any holding limit, does not model online-purchase discounts, does not work out the redemption price from a gold-price average, and does not handle early-exit windows or listed-market charges. Rules change in nearly every Union Budget and the tool’s defaults are not updated automatically, so the Reserve Bank of India notice, the Income Tax Department or a qualified chartered accountant governs.

What happens with zero or odd input?

A zero or negative investment returns a single line showing 0 g. A holding period of 0, which is also what a cleared box becomes, uses 8 years, and a holding period must be positive for the annualised line to make sense. A fall in gold shows a negative capital gain with a minus sign and zero gain tax, while interest is still added.
