Top 10 Best Feasibility Study Software of 2026

RealData fits feasibility study workflows that need repeatable assumptions across ROM estimate ranges and scenario variants. The tool focuses on converting technical and operational inputs into decision outputs that can be compared across options. The strongest fit signal is that outputs are designed for stakeholder review and internal gating, not just calculation.

A tradeoff is that RealData is less oriented toward deep resource-leveling and network-critical-path modeling, which shifts those activities to schedule tools. The best usage situation is an early-stage technical feasibility assessment where scenario modeling and cost-benefit screening drive option selection before detailed planning.

LivePlan centers on building operating assumptions and translating them into forecasted income, cash flow, and balance sheet statements, which helps teams run feasibility discussions without switching between spreadsheets and documents. The editor workflow makes it easier to keep a single source of truth for assumptions and the plan narrative, which reduces the mismatch risk that appears when financial spreadsheets and write-ups drift apart. Scenario modeling exists primarily as assumption variations inside the same planning structure, which suits go/no-go gate conversations when teams need fast comparisons across a small set of options.

A key tradeoff is that LivePlan’s modeling depth is oriented around small to mid-size planning cycles instead of deep capital project estimation rigor. Teams needing NPV sensitivity analysis with Monte Carlo simulation, or schedule-linked capacity throughput models, often hit limits because the core workflow is financial projection planning rather than engineering-style estimating. LivePlan fits best when a feasibility study depends on operating drivers, pricing assumptions, and expense structure that can be expressed in straightforward inputs.

Smartsheet supports feasibility work as linked sheets, where inputs such as cost fields and schedule dates can feed status dashboards and stakeholder reports. It includes form-based data capture, grid views, and workflow approvals that help teams implement go/no-go gates without building a custom application. Reporting consolidates progress across projects, which helps with weighted scoring and multi-criteria decision meetings even when data is maintained by different functions.

A tradeoff appears in deep engineering math workflows, because it is not an embedded NPV sensitivity engine and Monte Carlo simulation runtime. Smartsheet fits well when feasibility teams need coordinated WBS delivery, cost tracking, and decision documentation, while analysis calculations are either simplified or handled in external tools.

Autodesk Forma pairs early project feasibility modeling with an Autodesk-centric workflow that connects geometry, site constraints, and scenario outcomes. The core capability is scenario modeling that ties massing and layout inputs to quantitative reports for go/no-go gate discussions.

Feasibility analysis is built around structured assumptions, exportable baselines, and repeatable comparisons across alternatives. Automation and integration focus on keeping feasibility outputs consistent with downstream design intent rather than managing spreadsheets only.

Microsoft Project schedules feasibility workflows with WBS planning, Gantt dependency logic, and baseline tracking. It connects project data to Microsoft 365 through exports and file formats like MS Project XML and supports repeatable scheduling when project plans must feed downstream analysis.

Resource leveling and cost views help test schedule-feasibility tradeoffs while support for WBS import supports moving structured work breakdown structures into the plan. It is strongest for schedule-first feasibility studies and least suited for numeric investment modeling tasks that require specialized financial engines.

Oracle Primavera is a schedule and cost engineering suite used for feasibility studies that must connect early estimates to execution-grade planning. Primavera P6 integration supports importing and iterating WBS structures, managing Gantt dependency logic, and carrying schedules forward into capital planning workflows.

Primavera brings project controls depth for scenario modeling through risk and cost rollups, including sensitivity-style reporting patterns used around NPV and IRR hurdle assumptions. Governance is handled through enterprise-grade access controls and auditability aligned with program delivery environments.

PlanGuru turns budgeting, forecasting, and feasibility-style financial modeling into a workflow focused on capital and project assumptions. Its distinctive fit is the tight coupling between income-statement style modeling and scenario-driven decision outputs like NPV and IRR calculations.

The modeling experience centers on importing baseline financials and then testing business cases through structured inputs. For feasibility studies, PlanGuru is strongest when evaluation teams need repeatable assumptions, traceable scenarios, and fast iteration across go/no-go alternatives.

Fathom is feasibility study software that centers on structured workstreams and decision-ready outputs. It supports collaborative project documents with configurable templates for recurring gates like go/no-go check points and supporting evidence.

The workflow model emphasizes task status, assumptions capture, and traceability from inputs to outputs. It also offers an integration and automation surface through an API so schedules, risk registers, and external spreadsheets can feed the same study context.

Castaway builds and runs feasibility studies with a quantitative project model that supports scenario planning and cashflow based decision inputs. The workflow is oriented around financial evaluation outputs such as discounted cash flow and risk-adjusted assumptions, with iterative updates to see how results change.

Castaway also supports structured cost and schedule inputs to connect project thinking to go/no-go style outcomes. The main distinction is an emphasis on modeling iterations and decision metrics rather than document centric project reporting.

IdeaBuddy targets feasibility study workflows that start from structured assumptions and end in stakeholder-ready outputs. It supports scenario modeling across cost, schedule, and risk inputs, then keeps decisions attached to those assumptions during revisions.

The tool’s workflow focus favors go/no-go gate discussions and repeatable ROM estimates over free-form spreadsheets. Collaboration features help teams compare alternatives without losing traceability from input changes to computed impacts.
