Evaluate the cash difference between investing and not investing
A capital-investment MIS should show incremental cash flows at their expected dates, the discount-rate assumption, working-capital funding and recoveries, and the value lost if commissioning is delayed. NPV is the present value of those incremental future flows less the present value of the investment. A positive result under the approved assumptions supports the modelled economic case; it does not establish that cash funding, tax treatment, execution or demand risks have been resolved.
This practical finance guide is checked as at 23 October 2026. Its conceptual reference is ICAI Financial Management, Chapter 7: Investment Decisions. The examples are original decision workings, not statutory valuations or investment recommendations. To isolate the mechanics, they explicitly assume no income tax, GST, financing cash flows or inflation, a four-year model unless stated otherwise, a time-zero investment and year-end operating receipts. Actual approvals should add supported tax and timing consequences and a discount rate consistent with the cash-flow basis.
Build a decision cash-flow bridge rather than copying the profit forecast
List the cash flows that change because the proposal proceeds: equipment, installation, incremental operating receipts and payments, working-capital commitments, recoveries and disposal effects. Remove an irrecoverable historical study fee from the forward decision while retaining it in the accounting and project-spend reconciliation. Include the opportunity cost of an existing resource when the project sacrifices a feasible alternative benefit. A book value is not automatically either of those cash measures.
Distinguish project cash flows from financing flows. If the chosen project discount rate already reflects the cost of funding in the appropriate model, mechanically deducting loan interest again can double count financing. A genuine equity-cash-flow model uses a different flow and rate pairing. State the method instead of mixing the two. The illustrations exclude financing completely so their arithmetic cannot be mistaken for a loan repayment forecast.
| MIS component | Evidence and formula | Decision risk exposed |
|---|---|---|
| Incremental cash flows | Proceed case less the supported no-project alternative | Existing business cash can be counted as a project benefit |
| Present values | Cash flow at date t divided by (1 + rate) to power t | Timing and rate assumptions change value |
| Working capital | Initial/additional funding and realistic release dates | Profit can rise while cash remains committed |
| Terminal items | Supported disposal proceeds and recoverable balances | Unsupported end values can drive apparent viability |
| Monitoring | Approved model versus updated remaining cash forecast | A positive original NPV can deteriorate during execution |
Working-capital recovery is not a free offset at the start
Funding inventory or receivables at time zero and recovering it at the end of the project are different dated flows. Even full nominal recovery has a present-value cost. Reconcile the release assumption to actual collectible receivables, stock disposal and supplier settlement; do not assume every closing balance becomes cash on the last project day. Show terminal asset proceeds separately so the same recovery is not counted twice.
Treat discount rates and commissioning dates as assumptions to test
A decision can change when the discount rate rises, even if every rupee of forecast income remains unchanged. Select a supported rate for the actual risk, currency and cash-flow definition; an arbitrary borrowing quote is not automatically a complete project hurdle rate. Maintain a sensitivity range with its rationale. This guide’s 10% and 15% rates are illustrative inputs, not prescribed Indian regulatory rates.
Map commissioning to actual benefit dates. A year of delay can reduce NPV even if the same number of operating years is eventually achieved. Show whether the delay also changes capex timing, escalation, warranties, demand or other cash flows. The delay illustration changes only the receipt dates to expose that one effect; it is not a claim that actual project delay has no additional consequences.
Replacement decisions need a credible no-replacement case
When an existing asset already produces cash, the new asset’s entire inflow is not the incremental benefit. Compare the new and retained-asset alternatives over a consistent horizon, including any differing operating, sale, replacement and terminal values. A supported current disposal receipt can reduce the initial replacement outflow, while the lost old-asset inflows reduce future incremental benefits. If useful lives differ, build a consistent comparison rather than extending one asset’s forecast without evidence.
Use NPV to ask operational questions
Present the approved base case, rate sensitivity, delayed-start case and key cash assumptions in the capital-expenditure report. Assign ownership for capacity, demand, costs and collections. After approval, compare actual spending and commissioning with the model, and update the remaining forecast from the current decision date. Do not force already incurred cash into a new go/no-go decision merely to protect the original business case; retain that history in a separate total-project accountability bridge.
Worked illustrations
These illustrations use fictional facts and expressly stated assumptions. Amounts are Indian rupees unless a different currency or unit is specified. They are independent examples, not findings about any actual client.
Illustrative example 1: A transparent four-year base case
Invest ₹10,00,000 at time zero and receive incremental ₹3,50,000 at each year-end for years one to four. At an assumed 10%, the unrounded four-period annuity factor is approximately 3.169865446. The inflows’ present value is ₹11,09,452.91 and NPV ₹1,09,452.91. Calculations retain full precision until the displayed paise; using a coarse factor can alter a marginal decision.
Illustrative example 2: A sunk study cost belongs in history, not the new decision outflow
Use the base project, but assume a ₹50,000 study fee was irrevocably paid before the current approval decision and creates no further tax or refund effect in this illustration. Forward NPV remains ₹1,09,452.91. Adding that past payment to today’s ₹10,00,000 decision outflow would incorrectly show ₹59,452.91, lower by ₹50,000. Keep the fee in the total-project spending reconciliation.
Illustrative example 3: An existing resource can have an opportunity cost
Use the base project and assume it consumes a resource that could otherwise be sold now for a supported net ₹1,50,000, with no other cash or terminal differences. Economic time-zero commitment is ₹11,50,000. The same ₹11,09,452.91 inflow present value gives NPV minus ₹40,547.09. Ignoring the foregone sale would overstate NPV by ₹1,50,000.
Illustrative example 4: Full nominal working-capital recovery still has a present-value cost
Add ₹2,00,000 incremental working capital at time zero to the base project, with full recovery only at the end of year four. Its recovery present value at 10% is ₹1,36,602.69. Total NPV is ₹11,09,452.91 + ₹1,36,602.69 − ₹12,00,000 = ₹46,055.60, using unrounded inputs. The working-capital present-value cost is ₹63,397.31, despite full nominal recovery.
Illustrative example 5: Terminal sale proceeds must be discounted to their receipt date
Use the base project without the extra working-capital case, and add supported net asset-sale proceeds of ₹1,20,000 at the end of year four. Their present value at 10% is ₹81,961.61. NPV rises to ₹1,91,414.52 using unrounded amounts, an increase of ₹81,961.61. Adding ₹1,20,000 directly to today’s value would overstate the terminal benefit.
Illustrative example 6: A rate sensitivity can reverse the decision
Keep the base ₹10,00,000 outlay and four ₹3,50,000 year-end receipts, but test an assumed 15% instead of 10%. Inflow present value falls to ₹9,99,242.43 and NPV becomes minus ₹757.57. The cash forecast is unchanged, but the value conclusion differs. Both rates are sensitivity assumptions, not claims about the firm’s actual cost of capital.
Illustrative example 7: One-year delay reduces value even with four eventual receipts
Invest ₹10,00,000 now as in the base case, but shift the same four ₹3,50,000 receipts to the ends of years two through five. At 10%, the inflow present value is ₹10,08,593.55 and NPV ₹8,593.55. Compared with the base NPV, delay loses ₹1,00,859.36 of present value. This isolated timing case assumes no other delay-related cost or revenue change.
Illustrative example 8: Replacement is measured against retaining the old machine
Assume a new machine costs ₹10,00,000 now and replacing the old machine yields ₹1,00,000 net disposal cash now. Initial incremental outflow is ₹9,00,000. Over the same four-year horizon, the new machine generates ₹3,50,000 annual cash while retaining the old one would generate ₹1,50,000; incremental annual benefit is ₹2,00,000. Assume no differing terminal values or other cash effects. At 10%, incremental inflow present value is ₹6,33,973.09 and replacement NPV minus ₹2,66,026.91. Counting the entire new-machine inflow would ignore the viable no-replacement alternative.

Sixteen practitioner FAQs
1. Can forecast accounting profit replace cash flows?
No. Reconcile non-cash items, working capital and actual payment/collection timing to incremental cash.
2. Does every historical project cost belong in the current go/no-go outflow?
Irrecoverable past costs do not change the forward choice, though they remain part of project accountability and accounting.
3. Is a resource free because it is already owned?
Not necessarily. Include a supported benefit sacrificed by using it, where relevant to the choice.
4. Can book value automatically represent opportunity cost?
No. Establish the actual feasible alternative cash benefit and any associated consequences.
5. Why discount working-capital recovery?
A later release is not available to fund the initial commitment at time zero; timing has economic cost.
6. Must all working capital be assumed fully recoverable?
No. Support the expected collection, disposal and settlement amounts and dates.
7. Can salvage value be added without a date?
No. Model when net disposal cash is expected and avoid duplicating other terminal recoveries.
8. Are 10% and 15% mandatory project rates?
No. They are illustrative assumptions. Support the actual rate and its consistency with the flow definition.
9. Should loan interest always be subtracted from project cash flows?
No. Match the flow and discount-rate model; avoid counting financing costs twice.
10. Do these examples calculate after-tax investment values?
No. Taxes are explicitly excluded to isolate mechanics. An actual approval must model applicable tax effects consistently.
11. Does the model assume inflation?
The numerical cases assume none. If inflation is introduced, make cash forecasts and discount rates consistent.
12. Can four years of eventual receipts be treated the same despite a delayed start?
No. Their receipt dates change present value even where nominal totals are unchanged.
13. Does a positive NPV guarantee sufficient bank cash?
No. Funding availability and dated liquidity are separate checks.
14. Can the new machine’s entire inflow be called a replacement benefit?
Not when the retained machine would also earn cash. Compare the two supported alternatives.
15. Should coarse rounded discount factors decide a marginal project?
Preserve calculation precision and round presentation separately, especially near zero NPV.
16. How should the report be used after approval?
Track spending and commissioning against the approved case, update remaining cash forecasts and assign corrective actions without hiding historical performance.
Conclusion
Approve the model’s cash assumptions, timing and comparison basis together. Then use the same evidenced model to monitor execution, explain value changes and assess the next decision from its actual date.
