Every Question About
CapEx Intelligence Answered

CapEx = (Ending PPE − Beginning PPE) + Depreciation Allowance.

This is the internationally recognised formula for capital expenditure disclosure. It measures the net investment in long-term assets during a period, adjusted for depreciation that has already been charged. This follows IAS 16 (IFRS) and ASC 360 (US GAAP) standards precisely.

IAS 16ASC 360

NPV = Σ [CFₜ / (1 + r)ᵗ] − Initial Investment − Carbon Liability

Each annual cash inflow is discounted at your Hurdle Rate / WACC using the standard Discounted Cash Flow model. The ESG shadow carbon penalty (2% of CapEx, per TCFD guidelines) is then subtracted to produce a fully risk-adjusted Strategic NPV. A positive NPV signals value creation; negative signals value destruction.

DCF StandardTCFD Adjusted

The Secant Method — a numerical iteration algorithm that finds the discount rate (r) making NPV exactly zero. This is the same methodology used by CFA Institute, Investopedia, and Bloomberg terminal calculators.

The engine iterates up to 2,000 times with a convergence tolerance of 1×10⁻⁹ — giving you institutional-grade precision. Starting points are 5% and 25% to ensure stability across a broad range of cash flow profiles.

CFA Standard

Three IFRS/GAAP compliant methods available in the Scenario Vault (S button):

Straight-Line (SLM) — Equal expense every year. Best for assets with uniform utility over time (office equipment, infrastructure). Most common under IFRS.

Double Declining Balance (DDB) — Accelerated depreciation; 2× the SLM rate applied to reducing book value. Best for technology assets that lose value quickly in early years.

Sum-of-Years'-Digits (SYD) — Declining expense pattern but less aggressive than DDB. Good for vehicles and machinery with moderate early-year value loss.

IAS 16ASC 360

Coverage Ratio = Operating Cash Flow ÷ CapEx.

A ratio above 1.0x means the business generates enough operating cash to fully fund the capital investment from its own operations — a strong signal of financial self-sufficiency. This triggers AUTHORIZED governance status.

A ratio below 1.0x means external financing (debt or equity) would be required, triggering RISK_REJECTED status and escalating the project for board-level review. Many MNC governance frameworks require a minimum 1.25x–1.5x coverage for automatic approval.

PI = Present Value of Future Cash Flows ÷ Initial Investment.

A PI above 1.0 means the project creates value — every dollar invested returns more than a dollar in present value terms. It is especially useful when comparing multiple competing projects with different investment sizes, as it normalises value creation per unit of capital deployed.

PI > 1.0 = accept. PI < 1.0 = reject. PI = 1.0 = break-even.

Open the Scenario Vault (the S button on the left side) to access these controls:

Cash Flow Stress (-%) — Reduces all future cash inflows by this percentage to simulate market downturns, contract losses, or demand shocks. A 20% stress tests project viability in a significant recession scenario.

Inflation Adjustment (+%) — Adds this percentage to your Hurdle Rate / WACC to account for inflation eroding the real discount rate. For example, entering 2.5 with a base WACC of 8.5% gives an effective discount rate of 11%.

Re-execute after changing scenario parameters to apply the changes to all metrics.

No. SEOSiri uses a Sovereign Client-Side Architecture. Every calculation — NPV, IRR, depreciation schedules, payback periods — is performed locally inside your browser using JavaScript. Your financial figures never leave your device unless you explicitly:

1. Use the ERP Sync API endpoint (which you provide and control)
2. Trigger a backend audit validation (optional, and you can see exactly what is sent in the browser dev tools)

This means your most sensitive asset valuations, WACC assumptions, and cash flow projections remain completely private.

Your input values (PPE figures, cash flows, WACC, etc.) are saved to your browser's localStorage — a sandboxed storage area that is entirely local to your device and never synced to any server. You can clear this at any time via your browser settings (Settings → Privacy → Clear browsing data → Local storage).

No cookies, no tracking pixels, no analytics SDKs are loaded on the CapEx engine.

The backend at api.seosiri.com is completely optional. The engine works 100% without it. When online, it provides:

• Server-side audit trail confirmation (a second, independent validation of your results)
• Governance metadata tagging (project code, region, framework stamping)
• Download endpoint for text-format audit files

It is called silently in the background after client-side results have already been displayed — it never delays or blocks your output. If it is offline, you will see "OFFLINE" in the brand bar, but all engine functions work normally.

The Accounting Framework selector supports:

IFRS (IAS 16) — International Financial Reporting Standards, used in 140+ countries
US GAAP (ASC 360) — Generally Accepted Accounting Principles (USA)
AASB — Australian Accounting Standards Board
Ind AS — Indian Accounting Standards

The selected framework is stamped on your exported audit CSV and depreciation schedule, ensuring the report clearly identifies the applicable accounting basis for your auditors and board.

IFRSGAAP

ESG Carbon Liability = 2% × CapEx.

This is a shadow carbon price applied following the Task Force on Climate-related Financial Disclosures (TCFD) recommendations. Many global institutional investors and regulators now require capital decisions to account for the implicit carbon cost embedded in physical asset investments.

The carbon liability is deducted from raw NPV to produce the Risk-Adjusted Strategic NPV — giving you a more conservative, ESG-compliant project valuation that will hold up to institutional scrutiny.

Projects with titles containing "green", "solar", "sustainable", "renewable", or "ai" are automatically flagged as low-carbon and shown with an 85% green allocation ratio.

TCFD Standard

The Strategic Alignment Score (0–100) represents how closely the proposed capital project aligns with your organisation's declared strategic objectives — market expansion, technology transformation, operational resilience, etc.

The compliance gate rejects execution for scores below 40, preventing low-priority projects from consuming board bandwidth. A score of 75+ is recommended for projects to be considered for investment committee presentation. Most board-level submissions require 85+.

This score is set by the project sponsor and reviewed by the finance governance team as part of the Stage Gate process.

Approval authority is automatically determined by CapEx size, following standard MNC governance frameworks:

Under $5M → Department Head (Level 1)
$5M – $15M → Group CFO (Level 2 Executive)
$15M – $50M → CEO + CFO (Level 3 Strategic)
Over $50M → Board of Directors (Sovereign Level)

These tiers are aligned with common investment policy statements used by Fortune 500 and FTSE 250 organisations. Your organisation's own IPS thresholds may differ — use this as a baseline reference.

The exported CSV includes a complete Board-ready audit package:

• Project metadata: code, region, accounting framework, currency
• Key metrics: CapEx, Strategic NPV, IRR, Coverage Ratio
• Full depreciation schedule: year-by-year expense, accumulated depreciation, net book value
• Complete investment ledger: all execution records from the current session
• Engine attribution: SEOSiri Sovereign v3, Architect credit, timestamp

This CSV is formatted to be importable directly into Excel, Google Sheets, or your ERP system's import wizard. It is generated client-side — no data ever touches a server for this operation.

The Export Audit and Share features are part of the commercial tier of the SEOSiri CapEx Engine. The Gumroad license gate ensures that organisations using the engine for formal financial reporting are properly licensed.

Your one-time license key is verified against the Gumroad API and then stored locally in your browser — you only need to enter it once per device. The core calculation engine (NPV, IRR, depreciation, all displayed metrics) is completely free to use without a license.

The Share button (license required) copies a formatted summary line to your clipboard containing: Project name, CapEx amount, NPV, IRR, and a link to capex.seosiri.com. This is designed for quick distribution via email, Slack, Microsoft Teams, or board messaging platforms. It does not share your detailed inputs or raw financial data — only the headline metrics.

The ERP Sync bridge accepts a JSON file matching this exact schema:

{
  "end_ppe":       45000000,
  "start_ppe":     32000000,
  "dep_allowance":  2500000,
  "op_cash":       22000000,
  "project_code":  "PRJ-GLOBAL-2026",
  "residual":       500000
}

All values are in the native currency of the selected Subsidiary. The residual field is optional (defaults to 0). Export this format from your SAP Fixed Assets module, Oracle Asset Management, or Microsoft Dynamics 365 Finance using a standard financial extract query. Once uploaded, the engine auto-populates all fields and runs the calculation immediately.

See full integration guide in User Manual →

Yes. In the ERP Sync modal, use the "Fetch from Live API" option and paste your API endpoint URL. The engine will make a GET request to that URL and expects the same JSON schema in the response body.

Your ERP's REST API must return Content-Type: application/json and support CORS (or you need a proxy if the ERP is behind a corporate firewall). For enterprise deployments with custom authentication requirements, contact info@seosiri.com for bespoke integration support.

Any ERP that can export fixed asset data as JSON is compatible. This includes:

• SAP S/4HANA — via OData API or custom ABAP report
• Oracle Cloud Financials — via REST API asset query
• Microsoft Dynamics 365 Finance — via Data Entity export
• NetSuite — via SuiteScript JSON export
• Sage Intacct — via API query
• Any custom ERP or financial system with a REST endpoint

Map your system's field names to the SEOSiri schema (end_ppe, start_ppe, dep_allowance, op_cash) in your integration layer.

Yes — the full calculation engine is free: NPV, IRR, depreciation schedules, payback period, ROIC, profitability index, ESG analysis, stage gate governance, and the full dashboard are all available at no cost.

The Export Audit (CSV download) and Share features require a one-time commercial license from Gumroad. This supports continued development and ensures organisations using the engine for formal financial reporting are properly licensed.
