Engagement Ring Budget Calculator
Example: Your monthly income: 6000 $ · Months of salary to spend: 2 months · Price per carat (your target quality): 5000 $
| Ring budget | $12,000 |
| Estimated carats | 2.4 |
| % of annual income | 16.67% |
Worked example
On a $6,000 monthly income and a two-months rule, the budget is $12,000. At a target price of $5,000 per carat for the cut and clarity you want, that buys roughly 2.4 carats — though price per carat rises steeply at popular round sizes, so a slightly smaller stone can buy noticeably better quality. The $12,000 is about 17% of a $72,000 annual income, a useful reality check before you walk into a jeweler with a number in mind.
Frequently asked questions
Is the two-months-salary rule real?
It is a marketing guideline, not a financial rule. Spend what fits your budget and priorities. Many couples now spend far less than the old rule and put the difference toward a home or the wedding itself. This tool lets you set any months-of-salary target, including well under one.
Why does price per carat matter so much?
Diamond prices are not linear — a two-carat stone costs far more than twice a one-carat stone because larger stones are rarer. Price per carat also jumps at round milestones like 1.0 and 2.0 carats. Choosing a stone just under a milestone weight can stretch the budget considerably.
Should I finance an engagement ring?
Financing at a high interest rate can turn a one-time purchase into months of costly debt. Seeing the ring budget as a share of annual income helps you decide whether to save up first or scale the stone to what you can pay for outright.
What else affects the price besides carats?
The other three of the four Cs — cut, color, and clarity — plus the setting and metal all move the price. A well-cut smaller stone often looks better than a poorly cut larger one, so adjust your price-per-carat input to reflect the quality you actually want.
