MarginDeck is a local-first Mac app for indie developers. Split shared costs across products, compare estimated contribution profit, and review upcoming scheduled costs before they pile up—without becoming accounting software.

Hey Product Hunt —

I built MarginDeck because I could see my total monthly spend, but I still couldn't answer a more useful question: which product is actually carrying those costs?

When you run several products, AI tools, hosting, domains, developer accounts, design software, and marketing tools are often shared. Revenue is visible, but product-level contribution gets blurry.

MarginDeck gives me one local Mac workflow to:

• record products, revenue, and scheduled costs
• split shared costs across products with a monthly allocation history
• compare estimated contribution profit and trends
• understand portfolio burn and runway
• review upcoming scheduled costs for the next 30 days and 12 months
• catch future costs still allocated to stopped or archived products
• review read-only RevenueCat or Stripe revenue before applying it

I kept the scope intentionally smaller than accounting software. MarginDeck doesn't calculate taxes or claim to know “true profit.” It helps product builders organize the numbers they already have and make their own monthly decisions.

The app is free for one Product. Pro Lifetime unlocks multiple Products, comparisons, and cross-product allocation with a one-time purchase.

I'd especially value feedback on these things:

1. Does the shared-cost allocation workflow match how you think about a product portfolio?
2. Is estimated contribution profit the right level of clarity for a monthly product decision?

I'm also curious whether the Upcoming view gives enough context without making scheduled costs feel like confirmed charges.

Thanks for taking a look. I'll be here throughout the launch to answer questions.
