Is there a Maximum number of characters allowed in a URL calculated field?

I've created calculated fields with more than 6 fields - how many characters are in the field when it gets truncated? I know the out of the box URL field is 255 characters - and that is at the database level. Is that where you increased the size to 3000?

correct. So what ended up happening is I had one account where one of my tokens was really long and the user was unable to save the record. That's when I realized that the 255 characters wasn't enough. I updated that to 500 at the time and was good to go. 

Here is my calculated formula as it is right now: https://workshop.arvig.com/ROICalculator?roi_type=revenue&selected_drop_down=HPBX&date_of_service={estimation_form_date_c}&salesperson={created_by_name}&customer_name={account_name_c}&customer_address={customer_address_c}&z_location={z_location_c}&project

What i need is something closer to: 

https://workshop.arvig.com/ROICalculator?roi_type=revenue&selected_drop_down=HPBX&date_of_service={estimation_form_date_c}&salesperson={created_by_name}&customer_name={account_name_c}&customer_address={customer_address_c}&z_location={z_location_c}&project_management_cost={hpbx_project_management_c}&type_of_service=Hosted-PBX&internet_commit_rate={hpbx_internet_commit_rate_c}&monthly_recurring_revenue={hpbx_monthly_recurring_rev_c}&monthly_recurring_expense={hpbx_monthly_recurring_exp_c}&electric_equipment_cost={hpbx_equip_elect_metalicense_c}&installation_cost={hpbx_installation_expense_c} 

But every time I save this in my calculated field section it will cut off the remaining part of the formula where it's cut off in the top link.
