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 2026Commercial 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.
