Direct Mail Cost Calculator and Market Planner

Build an auditable campaign estimate from postage, production, and your own economics. The formula is visible, the assumptions are editable, and the result is downloadable.

Campaign assumptions

USPS rates verified July 2026

Commercial preparation and saturation eligibility required. This is a planning estimate, not a USPS quote or proof of eligibility.

Per-piece production

Fixed and campaign costs

The formula

Every dollar accounted for

Variable cost

Pieces × (USPS postage + print + addressing + list/data). Commercial rates require the preparation, entry, and sortation shown in the selected option.

Break-even

All-in cost ÷ contribution per conversion, rounded up. No industry response rate is inserted, so the scenario reflects your economics instead of a generic benchmark.

Rates, qualifications, and sources

The calculator uses USPS Notice 123 rates effective July 12, 2026. It is a planning estimate, not a USPS quote or proof that a mailing qualifies for a selected rate.

EDDM Retail is modeled at $0.260 per eligible piece. Commercial examples include a letter entered at the DSCF saturation price of $0.234 and a flat entered at the DDU saturation price of $0.258.

Verify dimensions, weight, route coverage, annual-fee status, address quality, sortation, and destination entry with USPS or a qualified mail provider before production.
