I Build Solo

Budgeting My Projects: $16K for 2025

In the last post, I set two goals for 2025: (1) Launch 3 apps by June, and (2) Grow each app to 2,000 MAU by the end of the year. In this post, I want to develop an appropriate budget to achieve these goals.

Criteria

1. Affordability

Since I’ll be funding the projects myself, I need to consider my affordability. Based on my current income and regular expenses, I can likely afford up to $20K for the entire year.

2. Expected tasks

To estimate the operating costs to build and launch apps and grow them to 2,000 MAU, I need to account for the following:

1/ Development

  • Design

    • Logo/app icon
    • App UI/UX
    • App Store product page
    • Website/landing page
  • Engineering

    • iOS app
    • Website/landing page

2/ Marketing

  • Organic
    • App Store Optimization
    • Blog posts
    • Social media
      • X
      • Short-form videos
  • Paid
    • App Store Ads
    • Social media ads
    • Influencer marketing

3. Tools needed

  • Hardware

    • MacBook Pro
    • iPhone
  • Software

    • Development
      • Xcode
      • Figma (or another design tool)
      • Cursor / Windsurf
      • LLMs (e.g., ChatGPT, API credits)
      • Server or backend tools
      • GitHub Pro (for Pages and private repositories)
      • Analytics tools (e.g., Amplitude, PostHog)
      • Typeform
    • Marketing
      • ASO and ASA research tools (e.g., AppFigures, AppTweak)
      • More to be added

4. Room for errors

I need to account for potential errors and unexpected expenses. A 10% cushion feels reasonable, especially given unknown costs related to marketing tools.


Calculating the budget

CategoryItemCost per AppNotes
DevelopmentDesign$500Hire for app UI/UX only; DIY other design tasks
Engineering$2,000DIY + hire for partial app development work
MarketingOrganic Marketing$0DIY (ASO, blog, social media)
Paid Marketing$2,000App Store Ads, social ads, influencer marketing
ToolsDevelopment Tools$279Includes Cursor/Windsurf, LLMs, server, GitHub
Marketing Tools$200ASO/ASA research tools

Summary:

  • Total cost per app = $2,500 (development) + $2,000 (marketing) + $300 (tools) = $4,800
  • Total for 3 apps = $4,800 × 3 = $14,400
  • Final total (with 10% cushion) = $14,400 × 1.1 = $15,840

Final budget for 2025: $15.8K
