We've remediated debt for clients running 10-year-old PHP, .NET, Java, and FreeSWITCH stacks — happy to walk through your numbers.

Assumptions & methodology

  • Engineering time drag = engineers × cost × % time lost to debt.
  • Incidents = number of incidents × average cost per incident.
  • Deploy friction = deploys/week × hours wasted × 52 × engineer hourly rate.
  • Feature delay = months delayed × monthly revenue tied to those features.
  • Codebase health tags add a small uplift (Amber 1.1×, Red 1.3×) to reflect compounding fragility.
  • Saved per year = total annual debt cost × % recovered.
  • 3-year ROI = ((Saved per year × 3) − Remediation budget) / Remediation budget × 100.
  • Payback (months) = Remediation budget / (Saved per year ÷ 12).
  • Conservative 0.7× / Optimistic 1.3× multiplier applied to the total annual debt cost.
  • These figures are decision support, not a guarantee. Numbers stay in your browser.
