The 5 Crazy Easy Steps to Creating Your Wedding Budget.

Step 1: Count Your Cash

How much you have to spend on the wedding is directly proportional to three sources of money: you and your fiancé(e)'s individual savings; the amount you can set aside from your current income; plus any contributions from parents or loved ones. Here's how to approach each:

Your savings: This isn't as simple as checking your bank account. Ideally, you and your partner each have three months of living expenses set aside in case of a job loss or health setback (separate from retirement funds). Subtract that in-case-of-emergency amount from your total balance in the bank, and that's how much you could put toward wedding costs.

Your monthly income: After you've made payments for existing debts, like student loans, set aside up to 10 percent of your earnings each month. "Establish direct deposits into a separate account for wedding expenses so it isn't just leftovers that get saved," says Erin Lowry, a personal finance expert and the author of "Broke Millennial: Stop Scraping By and Get Your Financial Life Together".

Any contributions from your parents: "Never assume your parents or other loved ones are willing and able to help cover the cost of a wedding," says Lowry. "But it certainly doesn't hurt to ask."

Step 2: Track Your Spending

Create a spreadsheet with three expense columns: Estimated, Modified, and Actual. Amounts under Estimated will be driven by research of costs in your area (check sites like Weddingwire and Thumbtack to find local averages for venues and vendors), proposals from the vendors you choose will go in Modified, and the final amount you pay them will go in Actual.

Adjust your estimates after calling in vendors' costs. Start with the venue because it's the biggest piece of the wedding pie and a major factor in determining guest count. When vendors give you estimates, verify if tax is included. If not, do the math yourself with state and local tax rates to adjust the proposal.

Add a column for the estimated tip. Write "included" if gratuity is factored into the vendor's price. (For example, caterers automatically tack on 15 to 20 percent of the total, which you pay in advance.)

Add a line item called Extras that equals 15 percent of your total budget to cushion for things you'll likely forget (invitation postage, parking valets) or won't anticipate in advance (corkage and plating fees). Never spend this money up front; you'll need it throughout the planning process as incidentals arise. Trust us.

Step 3: Prepare for Surprises

Before you sign on the dotted line of vendor contracts or start buying gift bag items, read the fine print, because expenses that seem small early on could add up quickly. If the total of the line item isn't in your overall budget, cut it.

Vendor Transportation: Hiring an out-of-town band or photographer? You might need to pay for a rental van or plane tickets. Double-check the contract to see what exactly is covered.

Setup and Breakdown Fees:  Cleanup isn't always included, and you may have to pay overtime rates depending on what time your reception ends.

Custom Cocktails: Signature drinks and spirits can add $3,500 to a 200-person wedding, says Calder Clark, a top wedding planner in Charleston, South Carolina.

Digital Access: Some photographers charge as much as $1,200 to view and share your photos online.

Envelope Stuffing: Some stationers charge as much as $7 per invite. To save, call your bridesmaids over, drink some wine, and DIY instead.

Planners: A full-service event designer can charge as much as $25,000 or even 20 percent of the total budget for a Kardashian-scale affair, but a day-of coordinator costs an average of $1,500. Before you enlist a pro, know what you have to spend and factor in that rate. Many venues require you to contract their in-house wedding coordinator or bring in your own outside wedding coordinator.

Step 4. Charge Responsibly

No matter how tempted you are to boost your cash flow with credit cards, don't go overboard. "Never charge anything that you can't pay off in 30 days," says financial expert Farnoosh Torabi, host of the So Money podcast. That is, unless you qualify for a card with a zero percent purchase APR, which lets you skirt interest payments as long as you pay your entire balance within a certain time frame (usually 12 to 15 months). Torabi advises mapping out a plan for how you intend to do that before swiping the plastic. For example, register for cash gifts that you can put toward a portion of the wedding and create a savings plan to cover the rest. If you do use a credit card, choose one with a generous cash back program.

You can use the rewards earned during that zero percent APR period toward the honeymoon or to pay off any remaining wedding expenses. But try to avoid signing up for more than one card, which can damage your credit score.
Step 5: Find Ways to Save

Over budget? These ideas will slash your spending in a meaningful way.

Change the venue: Raw spaces like barns and lofts seem like a steal, but you could spend a lot making them wedding-beautiful. "You may have to bring in tables, chairs, china, glassware, silverware, kitchen equipment for the caterer, even restrooms and AC or heat," cautions Sara Fay Egan, a partner at Jackson Durham Floral and Event Design in Dallas. Before you commit, estimate the total price of a wedding at that space versus one that includes all the basics.

Never have a B-list, and be ruthless with your A-list.
Edit the guest list: Each attendee costs far more than his or her meal when you consider the invitation, welcome bag, transportation, slice of cake, and favor. "Never have a B-list, and be ruthless with your A-list," says Clark. For the average 135-person reception, shrinking the guest list by 15 people saves you approximately $1,300.

Go off-peak: Have a winter wedding. Choose a Friday or Sunday. Or celebrate with mimosas over brunch instead of hosting a four-course, wine-paired dinner.

Build in time: To save for the wedding they want, 57 percent of brides said they were willing to prolong their engagement. "Negotiating is a lot more difficult when vendors know you're in a time crunch," says Torabi.

Host the ceremony and reception in the same place:  Doing so could save as much as $4,000 on transportation for the wedding party and guests.

Forgo a live band: The big-name ones can charge upwards of $30,000, while a DJ will cost a few thousand bucks.

Order all of your own paper items yourself: This means ordering or creating your own wedding invitations and appropriate inserts. Later, you'll be ordering place cards and table numbers and maybe programs and other things, too. Technology has made it easy to do a lot of this stuff on your own at home. The newlyweds-to-be choose the appropriate paper (most companies online will send free samples) and print them on their own printer, then assemble, stuff, and mail them. Even if you choose to order printed materials through a stationer, be sure to do it yourself. When you have your wedding planner assist or do it for you, it will cost you more, whether through her markup or because she'll likely be getting a thank you commission from the shop. Don't be afraid to have her proofread them; just do the creating, ordering, and assembling yourself.

Address your own invitations:  Paying for calligraphy is not cheap. If you must have calligraphy on your invites, consider buying a calligraphy pen and practicing until you get it right. It's not that difficult. And only an expert would notice it wasn't done by a professional. As a starting point, there are tons of tutorials online.

Go to the salon to get your beauty services done instead of having the stylist and makeup artist come to you: Whenever you have stylists come to your wedding venue or where you're dressing, you pay a significant outcall fee, and the prices are usually higher, too. You'll want to schedule it a little earlier in the day, but there's no reason why you and your bridesmaids can't get your hair and makeup done at a salon and then head to your venue to dress.
