Wedding Budget Calculator
Plan your wedding budget with typical cost breakdowns by category.
For 100 guests: $8,000 fixed + $250 × 100 = $38,000 ($380 per person).
Why This Calculation Matters
The Wedding Budget Calculator helps you make better events decisions by putting the math directly in front of you. Instead of relying on averages or guesswork, plug in your own numbers and see how the key inputs, rate, term, amount, and timing, interact. Small changes to any one of them can have outsized effects over years or decades.
How to Use This Calculator
- Enter your values in the input fields, each one has a label and help text explaining what to type.
- Results appear instantly as you type; there's no "calculate" button to press.
- Change any input to compare scenarios side by side.
All math happens in your browser. Nothing you type is sent to a server, saved, or shared.
Key Inputs to Get Right
The most important numbers are usually the interest rate and the time horizon. Over years or decades, small rate differences compound into large dollar differences, so it's worth sanity-checking the rate against current market data before acting on any result.

Frequently Asked Questions
How is the Wedding Budget Calculator cost calculated?
Total = $8000 fixed cost + $250 per guest × number of guests + extras. The fixed cost covers things that don't scale with attendance (venue, base setup); the per-guest cost covers food, drinks, favors, and per-person services.
What's a realistic budget for guests?
The defaults shown ($8000 base, $250/guest) reflect U.S. mid-tier averages in 2026. Higher-end events scale 2–4× this; budget-conscious events run 30–50% lower. Adjust the inputs to match your actual venue and vendor quotes.
Should I add a buffer?
Yes. Real-world spending typically runs 10–15% over budget due to last-minute additions (extra guests, upgraded items, gratuities, taxes). Either pad the per-guest input by 10% or add the buffer in the extras field.
What's NOT included in this estimate?
Variable costs that depend on your specific situation: travel/transport, accommodation for out-of-town guests, gratuities and taxes (typically 18–22% on food/beverage), and any add-on services. These are best added as a lump sum in the extras input.
