What the SEOSiri CapEx Engine Does

Your sovereign gateway to institutional-grade capital intelligence

The SEOSiri Sovereign CapEx Engine is a 100% browser-based financial intelligence platform that gives multinational finance teams, CFOs, and capital analysts access to institutional-grade capital expenditure analysis — without expensive ERP consulting fees, without sending your data to third-party servers, and without a setup process.

You enter your asset values and cash flows. The engine returns NPV, IRR, depreciation schedules, ESG-adjusted risk metrics, and a complete governance audit trail — all computed locally on your device using the same mathematical standards as Bloomberg, the CFA Institute, and Big Four advisory firms.

1

Enter Your Data

Input your PPE values, cash flows, WACC, and project details. The form remembers your inputs between sessions.

2

Execute in One Click

Hit Execute. All math runs in your browser — NPV, IRR, depreciation, ESG, payback, ROIC — in under a second.

3

Govern & Decide

Read your governance status, stage gate position, and approval authority tier. The engine tells you exactly who needs to sign off.

4

Export for the Board

Download a complete CSV audit report with full depreciation schedule and investment ledger — ready for board presentation or ERP import.

🔒 Sovereign Architecture

No financial data is ever transmitted to external servers. All calculations run locally in your browser. The backend API (api.seosiri.com) is purely optional — the engine works fully offline. Your most sensitive PPE valuations and WACC assumptions remain completely private.


1

Set Your Accounting Framework

IFRS, US GAAP, AASB, Ind AS — select the standard that governs your entity

The Accounting Framework & Residual section at the top of the input panel defines the compliance basis for your entire analysis. This is stamped on your exported audit report and depreciation schedule.

Framework Options

Residual Value

Enter the estimated residual (salvage) value of the asset at the end of its useful life. Under IAS 16, the depreciable amount is Cost − Residual Value. If you have no reliable estimate, leave this at 0 — the engine will depreciate the full cost to zero.

Project Code

Enter your internal project identifier (e.g. PRJ-APAC-2026-001). This code appears in the exported audit CSV, your investment ledger, and is sent to the backend audit trail for cross-referencing with your ERP.


2

Enter Asset & Cash Flow Data

PPE values, depreciation, and operating cash flow
Region & Subsidiary

Select the Operating Region (APAC, EMEA, AMER, SAARC) and Subsidiary. The subsidiary selection determines the currency symbol displayed throughout the dashboard and stamped on your audit report. Five currencies are supported: USD, EUR, BDT, GBP, JPY.

CapEx Formula
IAS 16 / ASC 360 Capital Expenditure Formula
CapEx = (Ending PPE − Beginning PPE) + Depreciation Allowance
Where PPE = Property, Plant & Equipment at gross carrying amount. The depreciation allowance is added back because it represents the capital "consumed" during the period that must be replaced to maintain the asset base.

Target Assets (Ending PPE)

The gross carrying amount of PPE at the end of the reporting period. Source: your balance sheet, fixed asset register, or SAP AM module.

Base Assets (Beginning PPE)

The gross carrying amount of PPE at the start of the period. The difference between this and Ending PPE represents new asset additions, net of disposals.

Depreciation Allowance

Total depreciation charged during the period. From your P&L statement or fixed asset schedule. Added back to the PPE movement to arrive at gross capital invested.

Operating Cash Flow

Cash generated from operations. Used to calculate the Coverage Ratio (OCF ÷ CapEx). Source: your cash flow statement, operating cash flow line.

Recovery Life (Useful Life)

The expected useful life of the asset in years. This drives the depreciation schedule — the engine will generate a year-by-year amortization matrix for exactly this many years. IAS 16 requires this to be reviewed at each year-end. Typical ranges: buildings (25–50 years), machinery (5–15 years), IT equipment (3–7 years).

Configure Cash Flows & WACC

Annual inflows, hurdle rate, and strategic alignment
Annual Cash Inflows

Enter the projected annual cash inflows generated by the project, separated by commas. These are the incremental after-tax cash flows attributable to the capital investment — not accounting profits.

Example: 4000000, 5500000, 6000000, 7500000, 8000000 represents five years of growing inflows. You can enter as many years as the project runs — the engine handles variable-length cash flow series automatically.

⚡ Cash Flow vs Profit

Use cash inflows, not accounting profit. Depreciation is a non-cash charge — do not deduct it from your inflows here (it is already accounted for in the CapEx formula). Use operating cash flows before financing costs but after tax.

Hurdle Rate / WACC

Enter your organisation's Weighted Average Cost of Capital (WACC) or project-specific hurdle rate as a decimal. For example, 0.085 = 8.5%. This is the minimum acceptable rate of return — the discount rate applied to all future cash flows in the NPV calculation.

If you do not have an official WACC, use your cost of equity as a conservative proxy. Most MNC hurdle rates fall between 7%–12%.

Strategic Alignment Score

Rate the project's alignment with your organisation's declared strategic objectives on a scale of 0 to 100. Scores below 40 are automatically rejected by the compliance gate. For investment committee submissions, target 75+. Board-level projects typically require 85+.

Execute & Read Your Results

Understanding every metric the engine returns

Click ⚡ Execute Strategic Allocation. All results appear in under a second — computed entirely in your browser. Here is what each metric means:

Primary KPI Cards

Total Capital Required (CapEx)

The computed capital expenditure using the IAS 16 formula. This is the primary investment figure for all subsequent calculations.

Coverage Ratio

Operating Cash Flow ÷ CapEx. Above 1.0x = AUTHORIZED (self-financing). Below 1.0x = RISK_REJECTED (requires external capital).

Strategic NPV

Risk-adjusted net present value. Discounted cash flows minus initial investment minus ESG carbon liability (2% TCFD shadow rate).

Target IRR

Internal Rate of Return — the discount rate making NPV = 0. Compare to your WACC. IRR > WACC = value-creating project.

Governance Status

✓ AUTHORIZED means Coverage Ratio > 1.0x — the project passes the primary liquidity governance gate.

✗ RISK_REJECTED means Coverage Ratio ≤ 1.0x — the project requires board-level review and alternative financing assessment.

Scenario Vault — Risk Simulation

Stress test your projections before presenting to the board

Click the S button on the left side of the page to open the Scenario Vault. This lets you model the impact of market uncertainty on your returns before committing to a capital decision.

Cash Flow Stress (-%)

Reduces all projected cash inflows by this percentage. Enter 20 to simulate a significant recession scenario (20% revenue decline). The engine recalculates NPV and IRR on the stressed figures.

Inflation Adjustment (+%)

Adds this to your WACC before discounting. Enter 2.5 to model 2.5% inflation layered on top of your base hurdle rate, raising the effective discount rate and lowering NPV.

Depreciation Method

SLM: Equal annual expense. DDB: Accelerated (2× rate on book value). SYD: Digit-weighted declining. All IFRS/GAAP compliant.

Re-Execute to Apply

After changing scenario parameters, click Execute again. The engine applies all scenario adjustments to NPV, IRR, depreciation schedule, and ESG metrics simultaneously.

ERP Ledger Sync

Connect SAP, Oracle, Dynamics, or any JSON-capable system

Click 🔄 Sync ERP in the header. You can either upload a JSON file exported from your ERP, or paste a live API endpoint URL. The engine auto-populates all fields and executes immediately.

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

All monetary values should be in the native currency of your selected Subsidiary. The residual field is optional (defaults to 0). Map your ERP's field names to this schema in your integration layer or export query.

✓ SAP Export Query

In SAP S/4HANA, use transaction AR01 (Asset Balances) or create a custom ABAP report selecting fields: ANLC-KOSTL (asset value), ANLC-NAFABJ (annual depreciation). Export via BAPI_FIXEDASSET_GETLIST in JSON format.
