Reliable Total Daily Energy Expenditure (TDEE) calculator?

General

I’m searching for a reasonably precise calculator for my Total Daily Energy Expenditure (TDEE). The ones I’ve tried on Google give me a wide range, from 1500 to 2500 calories. I’m unsure where to find a reliable calculator.

I’m also curious about whether reducing more than 500 calories from my TDEE is safe, provided it remains above 1200 after the reduction.

Additionally, I’m wondering if tattoos on my lower forearms will distort significantly if I lose a considerable amount of weight.

For a TDEE estimate that is more accurate, use the NIH Body Weight Planner. If you stay over 1200 calories, cutting 500 calories is usually safe. Significant weight loss may cause a little distortion of the tattoos.
