There's a website with a working calculator. But even that's flawed. I checked Voyager's 75,000 LY to get home at their max cruising speed of 9.975 and it showed me a bit over 5 years. Maybe they knew Janeway would stop to inspect every spec of space dust in between here and there when they cited the 70 year number.
Blame Janeway for wasting so much power on the holodecks, when they could have gotten home in season five!
