Engine Capabilities

Engineered for Long-Range Financial Clarity

Most calculators rely on simplistic fixed-return formulas. CronFolio gives you full stochastic simulation, branching events, and estate tax intelligence.

Stochastic Monte Carlo & FX Drift

Simulate thousands of paths with market return distributions, sequential volatility risk, inflation shocks, and foreign exchange currency drift (USD, JPY, EUR, GBP).

Milestone & Branch Timelines

Chain life events dynamically: home purchases with mortgage amortization, promotions, college tuition, pension annuities, sabbatical years, and early retirement.

100% Local-First & Zero Cloud

Your sensitive net worth, accounts, and financial blueprints never touch any remote database or cloud server. Runs completely offline in airplane mode.

Multi-Asset & Formula Engine

Track stocks, ETFs, cash, real estate, RSUs, and dynamic algebraic formulas. Model automated portfolio rebalancing and asset category constraints.

Estate & Inheritance Planning

Simulate estate distribution across beneficiaries, calculate inheritance tax thresholds, and preview asset transfer strategies across your timeline.

Native Multiplatform Performance

Built with modern Compose Multiplatform for blazing fast performance, instant undo/redo history, responsive charts, and fluid desktop keyboard controls.
