Wedding Savings Calculator
Wedding costs are driven by your total budget, what you've already saved, and how much time is left before the date. Enter those below to see the exact monthly amount you need to set aside, then add your guest count and any expected family contribution to see how your target compares to typical spending and what happens if you push the date back.
Used only to show your cost per guest — it doesn't change the savings figures.
Shown as a possible offset only — the headline target still assumes you save the full amount.

What your result means
With $30,000 still needed over 18 months, your recommended savings rate is $1,667 a month (about $385 a week). At your current pace of $800 a month plus bonuses, you're projected to reach $20,900 — a shortfall of $14,100.
$35,000 across 100 guests. Typical US weddings run $150–$350 per guest all-in.
The average US wedding runs about $30,000. Your $35,000 budget is above that by 17%.
Pushing the date back 6 or 12 months spreads your remaining $30,000 further, dropping the monthly target from $1,667 to those figures.
Your recommended monthly figure of $1,667 comes purely from dividing the $30,000 you still need by the 18 months you have left — it doesn't account for family help or guest count, which is why those live in the optional fields below rather than the core math.
You're currently contributing $800 a month, which is $867 short of the $1,667 needed to hit your budget on schedule. Over the remaining 18 months that gap compounds to roughly $15,600 of the projected shortfall.
At $350 per guest across 100 guests, cutting the list by 10 guests would free up roughly $3,500 of your total budget — often more than any single vendor negotiation.
Delaying the date changes only the denominator in this math: 6 more months lowers your target to $1,250, and 12 more months lowers it to $1,000. That only helps if your total budget doesn't drift upward in the meantime, which is common the longer a wedding is planned.
How to improve your result
- Close the monthly gap directly$867/mo
Raising your contribution from $800 to the recommended $1,667 a month is the single most direct fix — it removes the projected $14,100 shortfall entirely by the wedding date.
- Push the date back 6 months$417/mo lower
Spreading your remaining $30,000 across 24 months instead of 18 drops the monthly target from $1,667 to $1,250.
- Cut the guest list by 10%$3,500 saved
At $350 per guest, removing 10% of a 100-guest list saves roughly $3,500 off the total budget — often more impactful than any single vendor discount.
- Automate a dedicated wedding transfer$1,667/mo
Automating exactly $1,667 on payday into a separate account removes the temptation to skip a month, which is the most common reason couples fall behind their own targets.
- Redirect windfalls to the fund$1,000/yr assumed
Your plan already assumes $1,000 a year in bonus savings, contributing $1,500 toward the total. Tax refunds or work bonuses above that estimate shrink the shortfall further without touching the monthly budget.
- Confirm family contributions in writing earlyIf applicable
A confirmed $0 contribution would lower your monthly target to $1,667, but only bank on it once the amount and timing are agreed — otherwise keep saving at the full $1,667 rate.
Worked examples
18-month engagement, $35,000 budget
- Total budget
- $35,000
- Current savings
- $5,000
- Months until wedding
- 18
- Monthly contribution
- $800
- Yearly bonus
- $1,000
Remaining: $35,000 - $5,000 = $30,000 -> Recommended: $30,000 / 18 = $1,666.67/mo -> Projected: $5,000 + ($800 x 18) + ($1,000 x 1.5) = $5,000 + $14,400 + $1,500 = $20,900 -> Shortfall: $35,000 - $20,900 = $14,100
The couple is saving less than half the recommended rate. Closing the gap requires roughly doubling the monthly contribution, extending the timeline substantially, or reducing the budget.
12-month engagement, $18,000 budget, family help
- Total budget
- $18,000
- Current savings
- $3,000
- Months until wedding
- 12
- Monthly contribution
- $1,000
- Yearly bonus
- $500
Remaining: $18,000 - $3,000 = $15,000 -> Recommended: $15,000 / 12 = $1,250/mo -> Projected: $3,000 + ($1,000 x 12) + ($500 x 1) = $3,000 + $12,000 + $500 = $15,500 -> Surplus: $18,000 - $15,500 = $2,500 shortfall covered? No, still short by $2,500
Close to on pace, but a $250/mo increase or a confirmed family contribution of $2,500 would fully close the gap without extending the 12-month timeline.
