Technical debt & legacy platform benchmark
How much of your tech budget is spent keeping old systems alive? We review your platforms, integrations and delivery speed, estimate your technical debt and benchmark it against McKinsey's CIO survey and Stripe's developer research.
What the market looks like.
| KPI | Market reference | Top performers / note | Source |
|---|---|---|---|
| Tech debt as share of tech estate value | 20–40% | CIO estimates | 1 |
| New-product budget diverted to tech debt | 10–20% | — | 1 |
| CIOs seeing tech debt rise over 3 years | 60% | — | 1 |
| Developer time on tech debt / incl. bad code | 33% / 42% | Self-reported survey | 2 |
| Application modernisation services market 2025 | USD 22.67B | USD 51.45B by 2031 | 3 |
Legacy systems tax every new initiative, including AI. MarketsandMarkets values application modernisation services at USD 22.67 billion in 2025, growing 14.6% a year to 20313, as companies rebuild on platforms they own.
