Tell us what you found.

Corrections, calculators that give an unexpected result and pages that do not work are all welcome. If you want a reply, add your email.

What helps us check it

• The calculator URL.
• The inputs you used and the result you expected.
• The source that supports the correction, if you have one.

What we cannot do

HitEquals does not give personal financial, tax, medical or legal advice and cannot review an individual case. Never send passwords, account numbers, Social Security numbers or medical records: no calculation needs them.
