The basic wedding savings formula is simple: subtract the amount you have already saved from your target wedding budget, then divide the remainder by the number of months until the wedding.
Wedding savings formula
(Wedding goal − current savings) ÷ months remaining = monthly savings target.
If your target is $35,000, you already have $10,000 saved, and the wedding is 12 months away, you have $25,000 left to fund. That works out to about $2,083 per month before any additional buffer.

Use this as a planning estimate. Vendor contracts and local taxes determine your actual cost.
Make the target realistic before making it strict
If the monthly number feels too high, that is useful information. You can lower the total budget, extend the timeline, adjust the guest count, change priorities, or clarify expected family contributions. A savings plan works best when it reflects what you can comfortably afford rather than the wedding you feel pressure to replicate.
Keep your contingency separate
Final-month costs often include gratuity, alterations, postage, transportation, beauty services, final guest-count changes, and balances due across several vendors at once. Treating a contingency buffer as its own category makes it less likely that every available dollar gets committed early.
Update the plan when real quotes arrive
Your first savings target is based on estimates. As venue, catering, photo, entertainment, and other major quotes become real, replace assumptions with contracted amounts. The right monthly savings number can change during planning, and that is normal.
