When beginning you can make massive gains in performance and fitness before benefitting from a power meter.
In fact you might find that a power meter holds you back as you try to stick to 2.5w/kg all the way home, when you would be better off pushing harder up hills, spinning faster when your legs burn and aiming to improve your time
Fitness and strength needs progressive overload for your body to respond and adapt.
So I would keep riding and trying to get quicker, BUT spend time reading up about power, power meters, training with power, so when your fitness starts to level out and you decide you need to spank £500, you can buy the device that best meets your need and you know how to use it.
In the mean time if you want to track your progress, consider a gps and a free strava account ... You can see on your rides how fast you are over different segments and push harder to try and beat them ... With in a few weeks you will discover you are knocking minutes of your ride
