Planning concept calculators
Six calculators that teach a planning idea while they answer a question: inflation, real returns, doubling time, financial independence, college costs and life expectancy.
These tools make abstract ideas concrete. They're well suited to blog posts and newsletters, because each one explains a concept clients hear about but rarely see in their own numbers.
Inflation Impact
how much will things cost in 20 years
Savings, Taxes and Inflation
is my savings account keeping up with inflation
Rule of 72
how long does it take to double my money
Financial Independence (FIRE)
when can I retire early
College Savings
how much should I save for my child's college
Life Expectancy
how long will I live
