A fictional worked example with explicit study fees, incremental deduction assumptions, usable amounts and limits.
Fictional worked example. This does not describe a client, completed study or verified tax outcome. All deduction inputs are assumptions.
The fictional STR owner reconciles the seller inventory with separately purchased furniture. The assumed $35,000 is incremental depreciation versus the no-study baseline, not the entire furnishings cost or a promised allocation.
The example assumes 2,800 square feet, a $2,800 Stratum study fee, and $900 of separately engaged implementation work. It assumes $35,000 of additional depreciation compared with the no-study baseline, a 32% marginal rate, and 100% usability in the modeled period. None of these deduction or implementation inputs is a quote or a completed study result.
Assumed tax reduction = $35,000 × 100% × 32% = $11,200. Combined assumed cost = $2,800 + $900 = $3,700. The arithmetic difference is $7,500. This is an undiscounted early-period comparison; it is not a lifetime return, permanent savings estimate or recommendation.
If the $35,000 estimate accidentally includes items already on a separate schedule, it overstates the incremental result. Correct the asset register before using the calculation; participation and personal-use facts also remain separate review questions.
The preparer must establish the depreciation difference, when deductions can be used, the relevant marginal rates, state treatment, later-year depreciation and sale consequences. This example does not calculate bonus eligibility or assign asset lives. Use the fee-benefit tool to substitute adviser-supported inputs, then retain the complete multi-year analysis before commissioning the work.
