निवेश वसूली कैलकुलेटर

Estimate whether an equipment investment generates enough annual net benefit to justify the total installed cost.

• Total installed investment (currency)
• Annual gross benefit (currency/year)
• Annual operating cost (currency/year)
• Useful life (years)
• Residual value (currency)
• Discount rate (% per year)

net = gross benefit − operating cost; simple payback = investment ÷ net; NPV = Σ CFt ÷ (1+r)^t with CF0 = −investment; IRR = r where NPV = 0; lifetime ROI = (net × life + residual − investment) ÷ investment.

• Annual net benefit
• Simple payback — Undiscounted
• Discounted payback
• Annual ROI — Accounting ratio, not a discounted return
• Lifetime ROI
• NPV
• IRR — Returned only when the cash-flow series changes sign

• Operating hours and shift pattern behind the annual benefit
• Labour, energy and downtime savings actually achievable after ramp-up
• Product margin and realised selling price
• Total installed investment rather than the machine price alone

• Simple payback ignores the time value of money and must not be read as a return.
• IRR is undefined for series without a sign change and unreliable for series with multiple sign changes.
• Does not model financing cost, tax, inflation or currency risk.
• Single-currency model. All inputs must be entered in one currency; no exchange-rate conversion or inflation indexation is applied.
• Pre-tax model. Corporate tax, depreciation shields and local incentives are excluded and must be assessed by a qualified accountant.

This is a preliminary planning estimate, not a manufacturer quotation. Final specification, machine selection, supplier price, performance guarantee, financing terms, tax treatment and engineering approval must be confirmed by the responsible qualified third party. Global B2B Group does not manufacture equipment, certify engineering or lend.

• Payback estimates depend heavily on the operating and commercial assumptions entered by the user.
• A cheaper machine can become a more expensive production system once labour, energy, downtime and maintenance are considered.

Planning a real industrial project? Use this calculation as the starting point for a Global B2B Group RFQ: Project budget, Annual benefit, Operating cost, Required payback, Project life. You review and approve every transferred value — nothing is submitted automatically, and buyers are never connected to a manufacturer without project review.
