Calculator
Cost–benefit
Model any decision: solar, buy vs rent, EV vs petrol, pay cash vs finance, or roll your own.
Apply freed-up cash from each scenario
Each scenario below uses the monthly savings from your expense scenarios on the Expenses page. Add a home improvement (financed into the bond), extra deposits on the vehicle and solar install, and any extra monthly payment into the bond — the new monthly bond cost is recalculated automatically.
