nPlan Review 2026: AI Schedule Forecasting Trained on Past Projects

Updated October 13, 2026 – Tested Intelligence

Quick verdict: nPlan is the forecasting layer for teams who already have a schedule and want to know how much to trust it. Its AI, trained on a dataset the company puts at more than 750,000 past project schedules, forecasts the uncertainty of every activity – not just the finish date – and surfaces the work most likely to drive delay. It does not replace your scheduling tool, and pricing is not public, so expect an enterprise sales process.

What it is

nPlan, founded in London in 2017, is built around one idea: past projects are the best guide to how a new one will actually run. The company says its models are trained on the largest collection of past programmes it knows of – more than 750,000 schedules covering every capital project sector – and that archive is the foundation for everything the platform does.

You upload a schedule from your existing tool – it works alongside Oracle Primavera P6, Powerproject and Microsoft Project – and nPlan returns a probabilistic view: how uncertain each activity is, which milestones are exposed, and where risk is concentrated. ENR covered its adoption on the Transpennine Route Upgrade in northern England, where the team planned to use AI forecasting more frequently than traditional quantitative schedule risk analysis allowed.

Key features

• Activity-level forecasting: uncertainty predicted for every activity, milestone, project and portfolio
• Plan: create and edit schedules from scope documents with generative AI, plus automatic schedule-integrity checks
• De-risk: identifies risky activities and compares them against your uploaded risk register to show gaps
• Deliver: project and portfolio control-room views summarising risks, opportunities and progress
• Schedule comparison and interrogation across versions
• Works with existing schedules from P6, Powerproject and Microsoft Project rather than replacing them

Pricing

Pricing is not public. nPlan does not publish plans or per-seat figures on its website, and software directories list no price information for it either. Budget for a quoted enterprise agreement, and ask in writing what is included – number of projects, portfolios, users and forecast runs – before comparing it against the cost of in-house risk analysis or a rival forecasting tool.

Who it’s for

Owners, programme managers and major contractors running large capital projects – rail, infrastructure, energy and complex buildings – where a late finish is expensive and leadership needs a forecast it can defend. It suits teams that already produce proper CPM schedules and want an independent, data-driven check on them.

Who should skip it

Small builders and contractors without formal schedules will get little from it: nPlan analyses schedules, it is not a day-to-day job management system. If your need is lookaheads, weekly commitments and field updates, a field scheduling platform fits better than a forecasting engine.

Pros

• Forecasts every activity, so risk conversations focus on specific work, not gut feel about a date
• Trained on a very large archive of real past schedules, per the vendor
• Sits alongside P6, Powerproject and MS Project instead of forcing a platform switch
• Portfolio view helps owners spot systemic risks across multiple projects

Cons

• Pricing is not public – no way to budget without a sales conversation
• Value depends on schedule quality; a weak schedule limits what any forecast can tell you
• Aimed at major programmes, so it is likely overkill for small and mid-size jobs
• Forecasts inform decisions – your team still has to act on the risky activities it flags

FAQ

What does nPlan do?

It uses AI trained on past project schedules to forecast the uncertainty of every activity in your schedule, flag the activities most likely to drive delay, and compare those risks against your risk register.

How much does nPlan cost?

Pricing is not public. The vendor publishes no plans, and directories list no price, so cost comes from a quoted agreement based on your projects and portfolio.

Does nPlan replace Primavera P6 or Microsoft Project?

No. It works with schedules from P6, Powerproject and Microsoft Project, adding forecasting and risk analysis on top of the tools your planners already use.

Bottom line

nPlan is a specialist instrument: if you run major programmes and your current risk process is a workshop and a spreadsheet, its activity-level forecasts are a genuine step up. Get your schedules in order first, then ask for a quoted demo on a real past project so you can judge the forecast against what actually happened.
