1 Month - £25.53
1 Year - £183.83
Now im guessing that most people pay monthly, so how much interest is everyone paying if they pay Monthly compared to paying Yearly (£122.53 difference)?
Or look at it like this:
1yr is £183.83 / 12 = £15.32 per month.
So if you pay per month, then you're paying £10.21 more each month. Or £122.52 more per year.
Either way it looks like you pay more if you pay monthly.
If you paid the £183 on a credit card with 17% interest rate, the interest on that would be £31.25 per month. So as long as you paid it off in less than 4 months, you'd still be saving month.
(183/100 = 1.83 x 17 = £31.2511)
Is this for residential/consumer internet provision or business internet provision?
If you're talking about proper business connections, then you pay a higher rate for a better contention ratio (fewer people splitting the data bandwith), fixed IP address (for hosting domains and servers), better support and services level and so on.
