Using this utility

Plan with your own numbers, then verify the details.

This planner is for couples and planning partners who want one place to reconcile guest-dependent costs, vendor estimates, contributions, tax assumptions, and a contingency before making commitments.

How the planner builds the cost range

The result is a planning range built from the amounts and confidence choices you enter. Confirmed entries stay fixed; estimated entries use the visible low and high assumptions. Contributions are shown separately from the cost of the wedding so funding does not make the event appear cheaper.

Example: From vendor quote to planning range

Synthetic example: a catering quote lists a meal charge, a percentage service charge, delivery, and estimated tax. Enter each applicable cost once instead of folding the same service charge into both the quote and a separate fee. Mark settled figures as confirmed and uncertain figures as estimates with visible low and high assumptions. Add contingency as its own planning allowance rather than quietly increasing every line. If family members plan to contribute, record those contributions separately: they affect the amount the couple may need to fund, but not the all-in event cost. The result is a traceable planning range whose parts can be checked against the actual quote.

What the planner cannot verify

The planner supplies no market prices and cannot know a vendor contract, local tax treatment, service charge, gratuity practice, or last-minute change. Treat totals as an organized working model, then verify important figures with vendors and appropriately qualified advisers.

Questions before using the planning range

Does the planner provide average wedding prices?

No. Every amount comes from you. The expense library explains what a cost may include without claiming a market price.

How should I use the low and high totals?

Use them as editable planning scenarios, not predictions. They show how estimated entries change under the assumptions displayed in the planner.

Where is my plan saved?

Autosave and manual local save use this browser on this device. A downloaded .nwp file is the portable backup you control.

Is the tax estimate final?

No. Tax controls are planning assumptions. Actual taxability and rates can depend on jurisdiction, vendor practices, and the specific goods or services purchased.
