Hey Product Hunt! 👋
I built Corpus Planner because I wanted a clean, privacy-focused way to stress-test retirement readiness without linking my bank accounts or paying monthly SaaS subscriptions.
Most calculators assume static withdrawals and ignore sequence-of-returns risk or real-world inflation drag. Corpus Planner models both:
• The accumulation phase (multi-decade compounding & step-up contributions)
• The decumulation phase (dynamic monthly drawdown longevity curves)
Everything runs 100% locally on-device with zero ads and multi-currency support ($ · £ · € · ₹ · AED).
It's completely free to try on Google Play. I’d love your feedback on the drawdown math, UI/UX, or any edge cases you'd like modeled!
