Most online project price calculators use a single multiplier on hours × hourly rate. That misses the things that actually move the price: platform choice, urgency, content readiness, market rate, scope contingency. We run nine separate engines and combine their outputs.
Hours estimation engine
Maps your selected feature set to engineering hours, calibrated against 600 real projects.
Platform multiplier
Shopify vs Magento vs WordPress vs custom — different platforms have different real-world build costs even at the same scope.
Market rate engine
Hourly rates by geographic market. A US agency at $150/hr vs an Eastern European freelancer at $40/hr is a 3.75× difference on the same scope.
Pricing tier engine
Freelancer rates and agency rates calculated separately so you can compare what hiring a solo dev versus a full-service agency actually costs.
Risk engine
12-factor risk score (0–100) — feeds the contingency buffer.
Complexity engine
Synergy detection — multilingual + advanced search + Magento, for example, costs more than the sum of its parts.
Timeline engine
Project weeks with urgency adjustment.
Monthly cost engine
13 line items: hosting, SaaS, plugins, maintenance, content, security.
ROI projection engine
Break-even months across conservative / moderate / optimistic scenarios.
Most free project price calculators online have one of three problems. Here’s how this one is different.
"You won't see the result without your email."
Project Cost Estimator runs entirely client-side. No email gate, no signup. The full estimate appears the moment you finish the wizard.
Single hard-coded ranges with no inputs.
Some 'calculators' are just static cost-range pages. Project Cost Estimator runs 9 live engines on 30+ feature inputs — your number changes as you add or remove scope.
Numbers that look invented.
Every multiplier in the engine is calibrated against 600+ real projects across 6 markets. We publish the full methodology at /methodology.
Calculator that recommends one platform regardless of input.
We run a weighted scoring engine across 8 platforms — and tell you when none of the popular ones fit, so you can budget for custom code instead of getting talked into an off-the-shelf solution.
The full project price calculator runs across 9 engines and 30+ feature dimensions. Free, no email required.
