How to read the result
A headline discount is valuable only when the saving exceeds implementation cost and the renewal price still fits your operating budget.
Treat the switching-cost scenario as a stress test. Confirm price, taxes, cancellation notice, refund policy, and automatic renewal on the vendor's official terms before paying.

Every total exposes its assumptions.
Reviewed September 16, 2026. Currency is USD; tax, FX, and unentered overage remain outside the estimate.
Using the defaults: $19 × 5 × 6 + $39 × 1.10 × 5 × 18 + $400 = $4,831 over 24 months; year one is $2,257.
Compare the total with the no-promotion baseline, then add switching cost as a stress scenario. A cheaper first year can still create a higher renewal burden.

Worked scenario · 24 months
A 51% headline discount becomes a 4.9% total saving.
Five seats, $39 list price, $19 promotional price for six months, 10% renewal uplift, and $400 setup. Taxes and usage overages are excluded.
$19 × 5 × 6 = $570
$39 × 1.10 × 5 × 18 = $3,861
$570 + $3,861 + $400 setup. The no-promotion baseline is $5,080, so the actual saving is $249, or 4.9%.
Sensitivity check: adding the $900 switching estimate raises the exit scenario to $5,731. Cite the planning horizon and every input with the result.
Questions to ask before accepting a deal
Does promotional saving equal long-term saving?
No. Compare the implementation cost, post-promotion price, required term, and cost of leaving across the full planning horizon.
Should migration and training be included?
Yes. They are real adoption costs even when the vendor does not invoice them directly.
How should annual billing be compared?
Convert it to a monthly equivalent, but also record the upfront cash commitment, refund policy, cancellation deadline, and renewal date.
