The conventional wisdom in my research is that you should ladder (if possible) with the 10 year policy taking care of big expenses like your child’s college and paying off the mortgage.

Then the 20 year and 30 year would be lower since if you outlive the 10 year policy in theory you should have more money in the bank and more progress made on the mortgage.

All depends on your income but you could consider something like 1 million for 10, 750k for 20, and 500k for 30, if you feel like your family could use those amounts. If you die tomorrow they get 2.25 million.

Go to chatGPT with all your inputs. They’ll have a good recommendation.
