A few months into the implementation of Philadelphia's tax on sweetened beverages, numbers are starting to come in about the levy's impact, even as it continues to face legal challenges.

Here are some key figures to know about the 1.5-cent-per-ounce tax, which went into effect Jan. 1 and is levied on distributors.

$6.4 million: The amount of revenue the city brought in from the tax in February, the second month it was collected

$5.9 million: How much revenue the city brought in for January, the first month of the tax (that figure was preliminarily pegged at $5.7 million)

$2.3 million: How much the city had previously projected the tax would bring in during its first month

$91 million: The amount of tax revenue the city wants to bring in annually from the levy

$7.7 million: The approximate amount of how much the city will need to collect each month going forward to hit that target

30 to 50 percent: The drop in beverage sales some supermarkets and distributors have reported seeing so far (other businesses, however, have reported smaller impacts)

80 percent: The percent of revenue from the tax expected to go toward expanding early childhood education; rebuilding parks, libraries and recreation centers; and adding to the city's fund balance over its first five years (the city says it expects that number to rise to 97 percent starting in fiscal 2020, when those programs are fully implemented)

20 percent: The percent of money raised over the first five years set to go toward other programs and employee benefits, additional spending that was never mentioned as Mayor Kenney pitched the tax largely as a way to fund pre-K

36: Number of Pennsylvania legislators who have signed on to a brief filed in support of a lawsuit challenging the tax

$10.6 million: Amount the beverage industry has spent fighting the tax as of early April

$999,359: How much the city has spent on litigation fees and costs for the beverage tax lawsuit as of early April

4: Number of other cities in which voters approved soda taxes in November
