What Costimator does

  • Estimation

    Build complete BOQs from any SoR — measurements in, six audit-ready reports out. Hours of Excel work compressed into minutes.

  • Justification

    Tender justifications that take weeks in Excel finish in an hour. Enter market rates, get every SoR item recalculated through its full dependency tree.

  • NS Item Builder

    When the SoR doesn't have an item, you build your own. Costimator gives you the same rate-analysis structure used in official Schedules — composable, reusable, and audit-ready.

From the founder

From IES Officer to Founder, Costimator.

Kushal Singh, Founder of Costimator

I'm Kushal, the founder of Costimator. I originally built the platform while serving as an Executive Engineer at CPWD to solve a problem I faced daily: existing tools for estimation, justification, and market rate analysis simply didn't align with the realities of tendering projects. What started as a personal utility quickly gained organic traction among my peers. By 2025, the demand was so clear that I left the Indian Engineering Services (IES) to focus on Costimator full-time. Today, hundreds of engineers use it across estimation, justification, and tender preparation.

Frequently Asked Questions.

Will Costimator actually save me time?

Yes — and the savings are measurable. A tender justification that takes 2–3 weeks in Excel takes minutes in Costimator. Item searches return in 101ms. Full dependency recalculations complete in under 1 second.

Most users save 5–10 hours per estimate compared to manual workflows. Across a year of typical project work, that's hundreds of hours back.

Is my department supported?

CPWD DSR/DAR is fully live today. Indian Railways USSoR is live. MoRTH SoR/AoR, Karnataka SoR/AoR, and UP Irrigation SoR are all in active development with confirmed timelines.

The 14-day free trial gives you access to every department we support — try Costimator with your actual SoR data before deciding which plan fits.

If your department isn't on the list yet, drop us a line at the contact page — we add SoRs based on demand, and we already have partnerships in progress with multiple state governments and PSUs.

What if I need help during the trial or after I sign up?

Trial users get email support with 24-hour response. Pro and Diamond users also get phone support at +91 9458120296 during business hours.

We're a small team and we read every email — you won't get a chatbot or a ticketing-system runaround.

Is my data secure?

Yes. All data is encrypted in transit (TLS 1.3) and at rest. Your estimates, projects, and rate analyses are stored on enterprise-grade cloud infrastructure with daily backups.

We use Row Level Security (RLS) to enforce that only you can access your data — every query is filtered by your authenticated identity, with no exceptions. Costimator is built and operated within India. We don't share project data with third parties, ever.

How often do you update SoRs and rates?

When CPWD, Railways, MoRTH, or any supported authority publishes a new circular, schedule, or methodology update, we apply it within days — usually faster. You don't need to track changes yourself; the platform stays current automatically.

Costimator users are working with the latest official rates by default, not the rates that were current when they last downloaded a PDF.

Can I switch plans later?

Yes — Pro users can upgrade to Diamond within their first 14 days at a prorated cost. After that, upgrades happen at renewal.

Plan downgrades from Diamond to Pro happen at renewal as well. Switching the department covered by your Pro plan mid-year isn't supported, but you can change at renewal.

Do I need to install anything? Does it work on Windows / Mac / Linux?

No installation. Costimator is fully web-based — all you need is a browser and an internet connection. Because of that, it works seamlessly across Windows, Mac, Linux, and ChromeOS.

No setup. No dongles. No version-locked desktop apps.

What happens to my data if I cancel?

Your trial data is preserved for 14 days after expiry — upgrade within that window and continue exactly where you left off. For paid plans, data is preserved for 30 days after subscription end, after which it's deleted.

You can export all your estimates as Excel at any time — your work is portable, never locked in.
