Why switch from Monarch Money?
Monte Carlo retirement planning (Monarch doesn't have any)
Monarch is excellent for tracking what you spend today. Thermal projects where that spending leads. Run 10,000 Monte Carlo simulations across eight withdrawal strategies, model Roth conversions, Social Security timing, and tax-aware drawdown sequences. Monarch has no retirement planning at all -- not even a basic calculator.
Tax-lot tracking across every brokerage
Both Thermal and Monarch let you view investment holdings and allocation breakdowns. The difference is depth. Thermal tracks individual tax lots, surfaces unrealized gains by holding period, and feeds portfolio data directly into retirement projections. If you need to make tax-efficient decisions about which lots to sell, Thermal has you covered.
The Bridge connects daily spending to your retirement date
Most apps treat budgeting and retirement as separate problems. Thermal's Bridge feature shows exactly how today's spending decisions shift your projected retirement date and success probability. Cut $200 a month from dining and see the impact on your retirement in real time. No other personal finance app does this.
