Is there a calculator that can estimate how much you would’ve paid in funding fees on a perp?

For example, let’s say I opened a 1 BTC 2x long when Bitcoin was $17.1K on January 9, 2023. Assume the position size was 1 BTC.

Then, let’s say I closed it on March 4, 2024, at $64K.

Is there a calculator that can show how much money you would’ve lost to funding fees?

I know the fee differs between CEXs, but I’d like to assume it’s roughly the same across major ones and that’s good enough. So a calculator for any major exchange, or for average BTC funding fees, would be fine.

Reason: I’m trying to figure out whether small-leverage longs (1.5x–2x) are worth it if they stay open for such a long time.

Thanks in advance!
