Salon No-Show Profit Loss Calculator

Of 200 monthly bookings, 20 are missed and 5 refilled, leaving 15 unfilled slots. At $80 per service, $25 avoidable cost, $5 wasted cost, a $15 retained fee and 3% processing, the contribution gap is $645.75. A modeled 40% reduction recovers $258.30.

Gross service revenue forgoneUSD 1,200.00

Refilled slots are treated as equivalent completed services. Retained fees apply only to unfilled slots; refundable deposits are excluded.

Recovery uses your assumed reduction, not a forecast or a claim about reminder software.

This is a counterfactual contribution gap, not accounting net profit. Equivalent refills fully offset the missed service. Fees are allocated only to unfilled slots. Fixed overhead is unchanged. Negative gaps are possible when retained fees exceed contribution and wasted cost. No recommended cancellation policy or guaranteed recovery is implied.

What this calculator includes

  • Free, private calculations without signup.
  • Exact decimal arithmetic with validated inputs and transparent assumptions.
  • Editable inputs, reset example and global currency labels; no exchange-rate conversion.
  • Separate revenue forgone, contribution gap, refill offsets and retained fees.

How to use this calculator

  1. Count original bookings, misses and equivalent refilled slots for the same month.
  2. Separate avoidable completed-service costs from incremental wasted preparation.
  3. Enter only cancellation money actually retained after refunds.
  4. Test a reduction scenario and compare recovery with intervention costs.

Formula and calculation boundaries

Unfilled slots = missed appointments − equivalent refilled slots. Normal contribution = price × (1 − fee rate) − avoidable completed-service cost.

Gap per unfilled slot = normal contribution + extra wasted cost − retained fee × (1 − fee rate). Monthly gap = unfilled slots × gap. Recovery = monthly gap × assumed reduction. Annualized gap = monthly gap × 12 under an unchanged monthly pattern.

Checked example

Of 200 monthly bookings, 20 are missed and 5 refilled, leaving 15 unfilled slots. At $80 per service, $25 avoidable cost, $5 wasted cost, a $15 retained fee and 3% processing, the contribution gap is $645.75. A modeled 40% reduction recovers $258.30.

Negative gaps are possible when retained fees exceed contribution and wasted cost. No recommended cancellation policy or guaranteed recovery is implied.

Assumptions and limits

Frequently asked questions

Why is lost revenue higher than lost contribution?

Undelivered services can avoid product or variable labor costs. The tool separates the ticket value from the actual contribution gap.

Can I include salaried staff wages as avoidable cost?

Only if those wages genuinely disappear when the slot is unfilled. Unchanged salaries belong in fixed overhead and cancel out of this comparison.

Does a deposit eliminate the loss?

Only the portion actually retained offsets the gap. Refundable money remains a liability and is excluded.

What if I fill the canceled slot?

An equivalent replacement fully offsets that service. If its ticket or costs differ, model the difference separately.
