Multiple Compression Stress Test

Every SaaS founder considering an exit is asking sell now or wait? This calculator models what multiple compression, base, and expansion scenarios do to your exit value over 12 / 24 / 36 month horizons - using the same historical public-multiples data that powers the rest of this site.

Multiple Compression Stress Test

Sell now or wait? Stress-test your exit value against multiple volatility.

Public SaaS multiples have moved 70% peak-to-trough since 2021. Inputs below model your exit value if multiples compress 20%, stay flat, or expand 20% over your chosen horizon, while your ARR grows at your stated rate.

Expansion (7.2x)

Wedge analysis: The gap between the compression and expansion scenarios is £20.28M. Expansion upside versus selling today: £30.84M.

Compression / expansion bands of 20% reflect mid-cycle moves in public SaaS multiples. Peak-to-trough swings observed since 2021 are roughly 3-4x larger than this band; use 20% as a normal-cycle stress, not a black-swan scenario.

Why this matters in 2026

Public SaaS multiples have moved more than 65% peak-to-trough since 2021. Most founders considering an exit window in 2026 are working with a multiple expectation set against either the 2021 peak (much too optimistic) or the 2024 trough (potentially too pessimistic). The right framing is not what multiple do I deserve; it is what multiple is the market willing to pay across the realistic distribution of next 24 months.

Waiting always trades two things against each other: ARR growth (a multiplier you control) versus multiple movement (a multiplier you do not). A high-growth founder can usually outrun a 20% compression. A low-growth founder cannot. The calculator above surfaces the cross-over for your specific numbers.
