How This Calculator Works
Enter your ring budget, the return you expect on the savings, and how long until you want to buy. The calculator solves for the level monthly deposit that grows to the budget by the target date, with each deposit compounding monthly.
The Formula
Required Monthly Saving (Sinking Fund)
FV = goal amount, r = monthly rate (annual ÷ 12), n = number of months
Worked Example
Saving $6,000 over 2 years at 4% needs about $241 a month. You contribute roughly $5,773 of your own money; the small remainder is interest. Saving up to pay cash beats the common alternative of jewelry-store financing, which often carries deferred interest — the same trap as store cards, where missing the promo deadline charges interest retroactively on the whole balance.
Key Insight
The smart move with a ring is to set the budget from what you can comfortably afford and save to pay cash — not to anchor on the old 'two or three months' salary' marketing rule, which was invented by the diamond industry, not by financial sense. Two practical points: jewelry financing frequently uses deferred-interest promotions that become very expensive if not paid off in the window, so cash sidesteps a real risk; and the ring's price is highly flexible — lab-grown diamonds, alternative stones, and simpler settings can cut the cost dramatically without changing what the ring means. Decide the number you're happy spending, work back to a monthly saving, and keep the money somewhere safe since the horizon is short.

Frequently Asked Questions
How is the monthly ring saving calculated?
It's the level monthly deposit that grows to your budget by the target date, with each deposit earning the expected return compounded monthly — the standard sinking-fund formula. For $6,000 in 2 years at 4%, that's about $241 a month.
How much should I spend on a ring?
Whatever you can comfortably afford — there's no real rule. The 'months of salary' guideline was a diamond-industry marketing campaign, not financial advice. Set a budget that fits your finances and save toward it; the ring's meaning doesn't scale with its price.
Should I finance a ring instead of saving?
Saving to pay cash is usually better. Jewelry-store financing often uses deferred-interest promotions that charge interest retroactively on the full balance if you miss the payoff deadline — the same trap as store credit cards. Paying cash avoids that risk entirely.
Where should I keep ring savings?
Somewhere safe and liquid for a near-term goal: a high-yield savings account, money market fund, or short-term treasuries. Avoid stocks for money you'll spend within a year or two, since a downturn could leave you short right when you want to buy.
How can I lower the ring budget?
The price is very flexible. Lab-grown diamonds cost a fraction of mined stones with identical appearance, alternative gemstones (sapphire, moissanite) cost less, and a simpler setting or smaller center stone cuts the price further. Adjusting these can dramatically reduce the monthly saving needed.
When is this calculator unreliable?
Less reliable when natural vs lab-grown diamond substantial price difference (lab-grown 60-80% cheaper 2024), when inflation in diamond prices (lab-grown deflating 30%+ 2023-2024 substantial), when financing options (12-24 month 0% APR — savings approach preferred), when sales tax + insurance varies (1-2% of value annually), when custom vs retail substantial premium, or when brand premium (Tiffany/Cartier 30-50%) substantial.

Methodology & Review
Wedding ring savings = target ring cost × inflation × (1 + return)^n. Calculator returns required monthly savings. U.S. average engagement ring 2024 (The Knot): ~$5,500; median $3,500; lab-grown 2024 ~$2,000-$4,000 (substantial decline). Wedding bands $500-$2,000 typical. 'Three months salary' substantial outdated marketing rule. RELIABILITY: Reliable for documented target cost. Less reliable when (a) natural vs lab-grown diamond substantial price difference (lab-grown 60-80% cheaper 2024), (b) inflation in diamond prices (lab-grown deflating 30%+ 2023-2024), (c) financing options (12-24 month 0% APR common), (d) sales tax + insurance varies, (e) custom vs retail substantial premium, (f) brand premium (Tiffany 30-50%).
