Buying a car is something most of us dread.
For most people, it’s the second largest financial decision after housing. The process involves multiple variables like purchase price, interest rates, trade-in values, rebates, and loan terms that can be difficult to compare across different offers.
When a family need came up, I built an automotive purchase decision framework to help with the decision. The tool allows you to evaluate tradeoffs and quantify the opportunity cost of different options.
You can give it a spin here:
Cars are depreciating assets that start losing value the moment you drive them home. Since transportation in the US is heavily car-dependent, however, occasional purchases are necessary. Having a clear view of the numbers can help you make informed, intentional choices.
The Automotive Decision Framework lets you compare multiple offers side by side. It calculates total interest paid if you’re financing, identifies breakeven points between rebates and lower interest rates, shows how extra payments change payoff timing, and incorporates depreciation estimates.
The goal is to help you understand the tradeoffs so you can make a decision that aligns with your goals. When you’re evaluating different financing options or comparing vehicles at different price points, the tool provides a structured way to see the full financial picture.
