Wedding insurance covers cancellation, supplier failure, damage, and similar losses. Typical premiums are 50-300 depending on coverage level and wedding size. Payout equals the covered budget if a qualifying event occurs. This calculator shows expected value.

A 30,000 wedding budget with 3% cancellation probability and 150 insurance premium covering 100% of budget: expected payout 900, net expected value 750. The insurance is worth it statistically. At 1% cancellation probability, expected payout is 300 - still positive at this premium level.

Expected value and risk protection are different decisions. Even at negative expected value, wedding insurance caps downside risk on a major financial commitment. Most couples find 100-200 premium reasonable for peace of mind on a 20-50k spend. The tool shows when it's also financially favourable.

A worked example

Try the defaults: total wedding budget of 30,000, cancellation probability of 3%, insurance premium of 150, coverage percentage of 100%. The tool returns 750.00. You can adjust any input and the result updates as you type — no submit button, no reload. That's the real power here: seeing how sensitive the output is to one or two assumptions.

What moves the number most

The result responds to Total Wedding Budget, Cancellation Probability, Insurance Premium, and Coverage Percentage. Not every input has equal weight. Flip one at a time toward extreme values to feel which ones move the needle most for your situation.

The formula behind this

Coverage = budget × coverage %. Expected payout = coverage × probability. Expected value = expected payout - premium. Break-even probability = premium / coverage. Everything the calculator does is shown in the formula box below, so you can check the math against your own spreadsheet if you want.

Budgeting for the milestone

One-off life events have a habit of spreading — a wedding that "costs 15,000" routinely ends at 20,000 once related expenses are tallied. Use this tool to build the realistic figure, then add 10–15% for the items you haven't thought of yet.

What this doesn't capture

Life events generate side costs the figure doesn't include: time off work, lost income, travel for others, aftercare. Add 10–15% to the direct number as a buffer; the items you haven't thought of usually fill most of it.

Example Scenario

£30,000 £ wedding, 3% cancellation risk, £150 £ premium = $750.00.

Inputs

Total Wedding Budget:30,000 £
Cancellation Probability:3
Insurance Premium:150 £
Coverage Percentage:100
Expected Result$750.00

This example uses typical values for illustration. Adjust the inputs above to match a specific situation and see how the result changes.

Sources & Methodology

Methodology

Coverage = budget × coverage %. Expected payout = coverage × probability. Expected value = expected payout - premium. Break-even probability = premium / coverage.

Frequently Asked Questions

What cancellation probability is realistic?
Industry data suggests 2-5% of weddings face significant cancellation issues (venue failure, supplier bankruptcy, serious illness). Higher for destination weddings (6-10%) due to travel complications. Lower for small local weddings. Use 3-5% as a reasonable default.
What do policies actually cover?
Typical wedding insurance covers: venue closure, supplier bankruptcy, accident/illness preventing ceremony, damage to dress/rings, weather-related cancellation (some policies), ceremony cancellation due to death in immediate family. Check specific policy - some exclude existing medical conditions and force majeure.
Is wedding insurance worth it even at negative expected value?
Often yes. For a 30,000 wedding with no insurance, if something happens you lose up to 30,000. 150 premium caps downside at 150. Even at 1% probability (where expected value is -120 against 300 premium), many couples consider the peace of mind worth it.
When isn't it worth it?
Small weddings (under 5,000) where the loss would be manageable. Destination weddings with separate travel insurance (may cover similar risks). Weddings where suppliers provide their own guarantees. Anytime premium exceeds 2-3% of total budget is usually diminishing returns.
