Business valuation engine
Type your top-line, EBITDA, growth rate, and assets. We run five valuation methods side-by-side, weight them by industry norms, and give you a defensible asking range with the assumptions visible.

Result
Defensible range $1,425,923 – $1,929,189 · midpoint $1,677,556.
Growth premium: DCF runs 122% above triangulation — the growth-rate assumption is doing heavy lifting. Stress-test with growth at 50% of input.
- 1
Revenue multiple (1.2× service)
$1,680,000
$1,400,000 top line × 1.2
- 2
EBITDA multiple (5.5× service)
$1,540,000
$280,000 EBITDA × 5.5
- 3
DCF (5-yr + terminal)
$3,727,780
12.0% growth, 14.0% WACC, 3.0% terminal
- 4
Asset-based floor
$220,000
Tangible book value — typically the floor below DCF / multiple methods
- 5
SDE multiple (2.5× service)
$1,000,000
$400,000 SDE = EBITDA + $120,000 owner comp add-back
- 6
Weighted triangulation
$1,677,556
SMB weighting: 35% SDE / 20% EBITDA / 20% DCF / 15% rev / 10% asset

Asking range (±15%)
$1,425,923 – $1,929,189
Below the floor: walk away. Above the high end: justify with adjacent comps or strategic premium.
Assumptions & notes
- Industry multiples are mid-market norms — high-growth or high-multiple-margin businesses can clear 2–3× these. Distressed or declining can be half.
- DCF assumes EBITDA proxies for free cash flow. Real DCF subtracts maintenance capex + working-capital growth + tax.
- SDE method dominates for $1-5M businesses sold to individual buyers; PE-backed deals lean on EBITDA multiples.
Multi-scenario comparison
What if — ±20% on one input
| Scenario | Annual revenue | Headline | Δ vs baseline | Magnitude |
|---|---|---|---|---|
| −20% (cautious) | $1,120,000 | Defensible range $1,383,083 – $1,871,229 · midpoint $1,627,156. | $-336,000 | |
| Baseline | $1,400,000 | Defensible range $1,425,923 – $1,929,189 · midpoint $1,677,556. | 0 | |
| +20% (aggressive) | $1,680,000 | Defensible range $1,468,763 – $1,987,149 · midpoint $1,727,956. | +$336,000 |
Try the input with the highest sensitivity (above). The Δ column shows the dollar swing from a 20% move — that's how much room you have for a counter, raise, or hedge.
Goal seek
Solve for an input value
Pick the input you want to vary and the output you care about. We'll find the input value that gets you to the target. Bisection-based; converges in < 50 iterations.
Monte Carlo simulation
Distribution under input uncertainty (500 trials)
We perturb every numeric input with normal-distributed noise (10–25% sigma depending on input type) and run 500 compute trials. The output is a probability distribution, not a single number — closer to how finance actually works.
Most-leveraged inputs (sensitivity analysis)
Where to focus — what moves the answer most
Each input perturbed ±10%; measured impact on Revenue multiple (1.2× service). Higher elasticity = bigger lever.
- 1
Annual revenue
Elasticity ↑ 1.00× — 10% change in this input increases Revenue multiple (1.2× service) by 10.0%.
- 2
EBITDA (or owner cash flow if SMB)
Elasticity ↕ 0.00× — 10% change in this input affects Revenue multiple (1.2× service) by 0.0%.
- 3
Current owner compensation (added back for SDE)
Elasticity ↕ 0.00× — 10% change in this input affects Revenue multiple (1.2× service) by 0.0%.
- 4
Forward growth rate %
Elasticity ↕ 0.00× — 10% change in this input affects Revenue multiple (1.2× service) by 0.0%.
ShowMath is the only calc site that surfaces this. Adjust the highest-leverage input first — that's where small moves create big results.
