Is the two months' salary engagement ring rule real?

It originated from a De Beers diamond marketing campaign starting in the 1930s, not from any financial or cultural tradition. The suggested figure started around one month's salary and was later raised.

How much should I actually spend on an engagement ring?

Base it on what you can spend without dipping into savings you need elsewhere, not a percentage of income. Most Diamond Ateliers couples spend between SGD 3,000 and SGD 8,000.

Why do jewellery brands still reference salary-based spending rules?

Because the framing tends to push spending higher and is widely recognised, even though it has no basis in personal finance.

The Two Months' Salary Ring Rule: Myth, Not Tradition

If you've started shopping for an engagement ring, you've probably run into some version of "the rule": spend one month's salary, two months', sometimes three. It gets repeated so often that it sounds like an old custom. It isn't. It's a marketing line, and knowing where it came from is genuinely useful, because it changes how you should actually think about your budget.

Where the rule actually came from

Diamond engagement rings were not the norm for most of the early twentieth century. By some estimates, only around 10% of American engagement rings contained a diamond by the late 1930s. That changed largely because of a De Beers advertising campaign, developed with the agency N.W. Ayer, that ran from the 1930s onward and culminated in the now-famous 1947 tagline "A Diamond is Forever." As part of that campaign, De Beers introduced a suggested spending benchmark tied to salary, originally pitched as around one month's income, later raised to two months as the message was refined over subsequent decades. In some markets, including Japan, the campaign set the benchmark even higher, at three months. There was no consumer research or financial logic behind the specific figure. It was chosen because it sounded reasonable while still pushing spending upward, and it worked well enough that it is still repeated as received wisdom today, nearly a century later.

Why the rule doesn't hold up as a budgeting method

A rule pegged to salary ignores almost everything that actually determines what a ring should cost: your savings, your existing debts, what else you're both spending money on this year (a wedding, a home, children), and what your partner actually wants and would be comfortable knowing you spent. Two people earning the same salary can have completely different financial pictures. Treating a fixed percentage of income as a target, rather than a starting point for a conversation, tends to push people toward either overspending relative to their actual finances or underspending relative to what they could genuinely afford and would have chosen with clearer information.

A more useful way to set your budget

Start from what you can spend without financial strain, not from a formula. A few questions do more work than any percentage rule: what do you have saved specifically for this, without touching your emergency fund; what other major costs are coming in the next 12 months; and does your partner have any strong preferences about metal, stone type, or style that materially change the cost. From there, it helps to know what's actually achievable at different price points rather than picking a number in the abstract. Our guides to what you get at the SGD 2,000–3,500 entry tier, the SGD 3,500–8,000 range most couples land in, and the SGD 10,000+ premium tier break down what specifically changes at each level, so you can pick a number based on what you'll actually get rather than a formula with no relationship to the ring itself.
