How is software development cost estimated?

A two-sided marketplace with rich profiles, split payments and payouts, search, messaging and a moderation admin takes about 3,050 agency hours, 8 two-week sprints with 4 developers. That is roughly $392,000 with a US agency and $109,000 with a team in India.

build = Σ features (hours × complexity × stack) + screens × 10 h + integrations × 32 h + 40 h setup total = discovery + design + build + 10% hardening + QA % + DevOps + PM (12% + time-zone overhead) cost = Σ role hours × regional rate × agency tier; likely = cost × (1 + contingency) sprints = 1 + ⌈build ÷ (developers × 40 h × weeks × 0.8)⌉ + hardening

Worked example

A marketplace connecting buyers and sellers: 35 screens, rich profiles for both sides, split payments and payouts, search with filters, messaging, notifications, a moderation admin and four integrations. Built by a US agency (mid-market rates), 4 developers in 2-week sprints, with 15% contingency.

  1. 1Discovery (sprint 0): 76 hours, $10,500
  2. 2UI/UX design: 390 hours, $47,000
  3. 3Front-end development: 734 hours, $102,000
  4. 4Back end, platform and integrations: 576 hours, $80,000
  5. 5Hardening and launch: 131 hours, $18,000
  6. 6QA and testing: 360 hours, $32,500
  7. 7DevOps and CI/CD: 90 hours, $14,500
  8. 8Project management: 283 hours, $37,000
  9. 9Contingency reserve: 396 hours, $51,000
  10. 10Blended rate: $129 an hour across the team
  11. 11Schedule: 8 sprints, 16 weeks

About $392,000, within a range of $307,000 to $563,000, and 16 weeks from kickoff to launch.

Frequently asked questions

Why do marketplaces cost more than other apps?

Everything happens twice. Buyers and sellers need their own onboarding, profiles and dashboards; payments must be split, held and paid out with each seller verified (Stripe Connect or similar); and trust features such as reviews, messaging and moderation are expected from the first day. That is why the payments, search and admin features start at complex.

How can a marketplace MVP be cheaper?

Launch one side first, or handle one side by hand. Many marketplaces started with sellers onboarded by the founders, payouts made manually and messaging by email. Switch chat off and set payments and admin to simple above to see how much that saves.

How much does a two-sided marketplace cost to build with a team in India?

For the scope on this page, about $109,000, with a range of $85,000 to $156,000 at mid-market rates: 3,361 hours at a blended $32 an hour, delivered in about 16 weeks by 4 developers. Change the features and team above for your own scope.
