What we can help with

• Corrections. If a number, formula, or rate reference on the site looks wrong, please tell us — include the page and what you think is incorrect.
• Feature requests. Want a savings-goal mode, a retirement projection, or a different chart? We'd like to hear it.
• Bug reports. If something on the calculator behaves unexpectedly, include your browser and the inputs that reproduced the issue.

What we can't help with

BoostCalc is an educational tool, not a licensed advisor. We can't give individual investment, tax, or financial advice — please consult a qualified professional for decisions involving your own money. Please also avoid sending sensitive personal or account information by email.
