Hidden wedding costs: what couples forget to budget

By Forever Farrah Published 2026-09-17.

The wedding costs couples most often leave out of their budget, from service charges, sales tax and tips to alterations, postage, fees and overtime.

The costs couples forget are rarely big single items. They are percentages and small fees attached to everything else: service charges and sales tax on catering, tips, alterations, postage, vendor meals, delivery and overtime fees, and cake cutting or corkage charges. Ask every vendor for an all-in price that includes these, and keep a buffer of around 5 to 10% (our suggestion) for what's left. In a 2025 survey, 32% of newlyweds went over budget.

Service charges and tax

The headline catering price is often per person before service charges and tax. Many venues and caterers add a percentage service charge to the bill, and sales tax may then apply on top.

• A service charge is not a tip. The IRS says a payment is a tip only if the customer voluntarily decides to pay it and determines the amount, so a mandatory charge on your contract is not a gratuity, and it may not go to the staff. Ask your venue where it goes.
• Tax may apply to more than the food. In Washington, for example, caterers must collect retail sales tax on their total charge, including meals, equipment, decorations and the catering service itself. Rules and rates differ by state and country, so ask your caterer what is taxable where you're marrying.

The costs couples most often miss

Hidden wedding costs and what to ask

Cost	What to ask or check
Service charge	Is it included in the per-person price? Does any of it go to staff?
Sales tax	Is tax included? Is it charged on the service charge and rentals too?
Tips	Is gratuity already in the contract? Who is customarily tipped where you live?
Vendor meals	Does your contract require meals for the photographer, band or planner?
Cake cutting and corkage	Is there a fee to serve a cake or drinks you bring in?
Delivery, setup and breakdown	Are they included for rentals, flowers and the cake?
Overtime	What does an extra hour cost for the venue, band, DJ and photographer?
Travel fees	Do vendors charge mileage or accommodation outside their area?
Alterations	Are they included with the outfit, or priced separately?
Postage	Have you weighed a full invitation suite?
Marriage licence	What does it cost where you're marrying?
Insurance and permits	Does the venue require event liability insurance, or a permit for a public space?

Tips

Whether and whom to tip depends on local custom and on what your contracts already include. Check every contract for an included gratuity first, so you don't tip twice. Then decide on any tips in advance, put cash in labelled envelopes, and give them to one trusted person to hand out at the end of the night. Budget for them now rather than finding the money on the day.

Postage and stationery

Invitations cost more to post than most couples expect. The US Postal Service raised the Forever stamp to 82 cents on July 12, 2026, and each additional ounce on a letter costs 29 cents. Square, rigid or lumpy envelopes, or ones with ribbons or wax seals, must be hand-cancelled and pay a nonmachinable surcharge even under one ounce. Take a fully assembled invitation to the post office to be weighed before you buy stamps, and remember return postage if you include reply cards. A wedding website with online RSVPs removes that second stamp.

Attire and beauty

Alterations are rarely included in the price of an outfit, and several fittings may be needed. Add shoes, undergarments, accessories, steaming or pressing, and hair and makeup trials, which are often priced separately from the wedding-day booking. How much to spend on a wedding dress covers the full outfit budget.

Feeding and looking after vendors

Photographers, videographers, planners and musicians who work through the reception often have a meal written into their contract. Do you have to feed wedding vendors? explains what's customary. Add vendor meals to your catering headcount.

The small things that add up

• Welcome bags and wedding party gifts.
• Rehearsal dinner if you're hosting one.
• Guest transport between ceremony and reception.
• Extra hours when the party is going well.
• Emergency kit items: wedding day emergency kit has the list.
• Your own travel and accommodation for a wedding away from home.
• Dress cleaning or preservation afterwards, if you want it.

How to protect your budget

1. Ask every vendor for an all-in quote with service charges, tax, delivery and travel included.
2. Read contracts for minimums, overtime rates and required vendor meals before you sign. Questions to ask a wedding venue covers the venue side.
3. Keep a buffer line in your budget and don't spend it early.
4. Track deposits and balances against each vendor so nothing surprises you in the final weeks.

Budgets go over more often than not: in a LendingTree survey of 1,050 US newlyweds (March 2025), 32% went over. Wedding budget mistakes covers the other common traps.

Frequently asked questions

Is a service charge the same as a tip?

No. The IRS treats a payment as a tip only if the customer chooses to pay it and sets the amount. A mandatory service charge is part of the bill, and it may not go to the staff, so ask your venue.

Is sales tax charged on wedding catering?

In many places, yes, and sometimes on the whole bill including service and rentals. Washington, for example, taxes caterers' total charge. Rules differ by state and country, so ask your caterer.

How much does it cost to mail a wedding invitation?

In the US, at least an 82-cent Forever stamp from July 12, 2026, plus 29 cents per extra ounce, and a nonmachinable surcharge for square or rigid envelopes. Weigh an assembled invitation first.

How much should we set aside for hidden costs?

We suggest a buffer of 5 to 10% of your total budget. It's our rule of thumb rather than survey data, but it covers most of the items on this list.
