People type this into search every day: how much to save for a wedding.
The usual answer is a national average. I am not going to invent one. The useful number is the budget you can fund, split into a venue, the other fixed bills, a contingency, and what is left for each guest.
This page is a labeled example. It is not a quote from a venue, and it is not personalized financial advice.
Estimate the day, then divide the leftover
The CFPB planning for life events and large purchases worksheet names a wedding in the first paragraph. Estimate the cost. Decide how much you will save and how much you might borrow. Look for ways to cut the bill. Then use a savings plan so you know the weekly or monthly amount.
Their savings plan worksheet is the cash version of that last step. Target divided by months. No interest in that table.
The wedding budget calculator does the split that comes before the monthly deposit:
available after fixed costs and contingency ÷ guests
Venue and other fixed costs are entered separately. The leftover per guest is meant to cover food, drinks, stationery, and favors. The tool says that in its assumptions.
Fig 1
Fixed bills, then the guest line
Contingency is a slice of the whole budget, taken first
Subtract the venue, the other fixed costs, and the reserve. Divide what remains by the guest count.
A 10% reserve on a $30,000 plan is $3,000. That cash is there because something on the day will cost more than the first quote. It is not a decoration category.
The published $30,000 / 90-guest example
Here are the calculator defaults:
- total available budget: $30,000
- guests: 90
- venue fixed cost: $6,500
- other fixed costs: $8,500
- contingency: 10%
Reserve: 30000 × 0.10 = $3,000.00
Fixed costs: 6500 + 8500 = $15,000.00
Variable guest budget: 30000 − 15000 − 3000 = $12,000.00
Available per guest: 12000 ÷ 90 = $133.33

Where $30,000 goes
Calculator defaults. 90 guests.
Fixed
$15,000
Guests
$12,000
Reserve
$3,000
Fixed costs take $15,000.00, half the plan.
Guests get $12,000.00. The 10% reserve is $3,000.00.
$133.33 is the ceiling for food, drinks, paper, and favors on this path. It is not a catering quote. If the meal you want is $90 and drinks are $40, that pair already uses $130 of the $133.33. Stationery and favors have to share $3.33, or the fixed lines have to shrink.
This $30,000 is the number the calculator ships with. It is not an average wedding in your city.
Guest count changes the plate, not the hall
Keep the $30,000, the $15,000 of fixed costs, and the $3,000 reserve. The leftover stays $12,000. Only the divisor moves.
- 60 guests: 12000 ÷ 60 = $200.00 per guest
- 90 guests: $133.33
- 120 guests: 12000 ÷ 120 = $100.00

| Category | Per guest |
|---|---|

| 90 guests | 133.3 |
| 120 guests | 100 |
Sixty guests leave $200.00 each.
One hundred twenty guests leave $100.00 each. Ninety sits in the middle at $133.33.
Raising the list from 90 to 120 does not add $133.33 × 30 = $3,999.90 to the bill, because the leftover is already capped. You get a thinner plate, or you raise the total.
The other direction is a smaller day. Same 10% reserve, $18,000 total, 60 guests, $4,000 venue, $5,000 other fixed.
Reserve: 18000 × 0.10 = $1,800.00
Fixed: $9,000.00
Variable: 18000 − 9000 − 1800 = $7,200.00
Per guest: 7200 ÷ 60 = $120.00
$120.00 per guest on an $18,000 plan is in the same neighborhood as $133.33 on the $30,000 plan. The hall and the other fixed bills did the work.
The venue eats the guest line first
Keep 90 guests, $30,000, $8,500 of other fixed costs, and 10%. Raise the venue from $6,500 to $10,000.
Fixed costs: 10000 + 8500 = $18,500.00
Variable: 30000 − 18500 − 3000 = $8,500.00
Per guest: 8500 ÷ 90 = $94.44
That $3,500 venue increase cut the guest budget by $3,500. 3500 ÷ 90 = $38.89 less per person. The reserve did not move, because 10% is taken from the $30,000, not from what is left.
A $45,000 version with 120 guests, same $15,000 fixed, same 10%:
Reserve: $4,500.00
Variable: 45000 − 15000 − 4500 = $25,500.00
Per guest: $212.50
More total budget is the only way the per-guest line rises once the hall and the guest list are set.
The reserve is a percent of the whole plan
Keep the $30,000 and the $15,000 fixed. Change only the contingency.
- 5%: reserve $1,500.00, variable $13,500.00, per guest $150.00
- 10%: reserve $3,000.00, variable $12,000.00, per guest $133.33
- 15%: reserve $4,500.00, variable $10,500.00, per guest $116.67
Each extra 5 points of reserve takes $1,500 from the guest pile on this $30,000 plan. 1500 ÷ 90 = $16.67 per person.
I would rather cut a decoration line than spend the reserve before the week of the event. That is a preference, not a rule. The calculator will not stop you from setting 0%. The CFPB large-purchase tool still wants a researched cost, not a hopeful one.
The monthly deposit is a different calculator
Once the $30,000 is the target, the savings goal timeline post is the monthly loop. A wedding date is a deadline, so start at 0% return. The CFPB worksheet does the same cash split.
Sinking fund contribution is that worksheet with a name. No investment return.
From $0, $30,000, one person:
- 12 months: 30000 ÷ 12 = $2,500.00 a month
- 18 months: 30000 ÷ 18 = $1,666.67 a month
- 24 months: 30000 ÷ 24 = $1,250.00 a month

$2,500 a month, 0%, prints 1 year and lands on $30,000.00.
$1,667 a month, 0%, prints 1 year 6 months and $30,006.00, because 1667 × 18 = 30,006.
Already have $4,000. Eighteen months left. Sinking fund: (30000 − 4000) ÷ 18 = $1,444.44 a month. Already funded: 4000 ÷ 30000 = 13.3%. Twenty-four months: $1,083.33.

The monthly budget planner leftover on its defaults is $900.00. That is 21.4% of the $4,200 take-home on that page. Put $900 a month toward $30,000 from $0 at 0% and the timeline is 2 years 10 months. Final balance $30,600.00.
From $4,000 already saved, the same $900 at 0% is 2 years 5 months and $30,100.00. At 3.5% it shortens to 2 years 4 months, final $30,557.66, growth $1,357.66. Most of that pile is still money you deposited.

Year 1 is $14,800 at 0% and $15,117 at 3.5%.
Year 2 is $25,600 at 0% and $26,630 at 3.5%. The $30,000 target is still ahead.
SEC Investor.gov’s compound interest definition still applies. On a two-year cash goal the effect is small. The date on the invitation does not wait for a return.
The 50/30/20 budget post is the leftover month. $2,500 a month for a one-year $30,000 plan does not fit inside a $900 leftover. Either the date moves, the $30,000 shrinks, or the leftover has to rise. I would run the smaller $18,000 plan against that $900 before I promised the default.
The CFPB emergency fund guide wants a cash buffer that is not the wedding account. Their savings-plan worksheet asks about an emergency pile first. The emergency fund defaults need $18,900.00 for six months of essentials. A $30,000 wedding goal does not replace that number.
Drinks are a purchasing quantity
The per-guest leftover has to buy real servings. The party drink quantity calculator stocks a bar. It is not a consumption target. The tool says that, and it adds a line about alcohol-free choices.
Defaults are 40 guests, 4 hours, 65% drinking alcohol, 1.5 drinks in the first hour, 1 drink in each later hour.
Alcoholic servings: 40 × 0.65 × (1.5 + 3 × 1) = 26 × 4.5 = 117
Non-alcoholic servings: 40 × max(2, 4 × 0.75) = 120
Water: ceil(40 × 4 × 0.3) = 48 L, shown on a US profile as 12.7 gal
Scale that pace to the wedding default of 90 guests, same 4 hours and 65%.
Drinking guests: 90 × 0.65 = 58.5, printed as 59
Alcoholic servings: 58.5 × 4.5 = 263.25, rounded up to 264
Non-alcoholic servings: 90 × 3 = 270
Water: ceil(90 × 4 × 0.3) = 108 L, shown as 28.5 gal

Five hours at 90 guests: alcoholic 322, non-alcoholic 338, water 35.7 gal.
Sixty guests at the default pace: alcoholic 176, non-alcoholic 180, water 19 gal.
Those servings come out of the $12,000 guest pile, or out of a catering line you typed under other fixed costs. If drinks are in the venue contract, do not buy 264 extra servings on top.
Open the wedding budget calculator with the total you can fund, the guest list, and the hall quote. Use the savings goal timeline or the sinking fund for the monthly deposit. Use the party drink quantity calculator when the leftover has to stock a table.
