See the real value of your cash

Look, most people ignore inflation and end up broke. You need to know how much your money is actually worth after prices rise. Use `compute_absolute_inflationary_erosion` to get the hard number on how much your currency lost. It’s a reality check that keeps you honest about your savings.

Check your purchasing power

It’s not just about the balance in your account. It’s about what that balance can actually buy at the store. Run `calculate_purchasing_power_ratio` to see how much of your original buying power remains. Do the math before you assume you are ahead.

Find your true investment yield

Nominal returns are a trap for the lazy. You need the Fisher equation to strip away the noise and find the real growth. Call `get_real_return_percentage` to calculate your actual return rate. This MCP keeps your investment analysis grounded in facts.
