Leasing equipment can be a way to extend your credit resources if you need to do that. Typical lease calculations, though, often amount to 12% and higher effective interest rates. If you have other borrowing options, (besides credit cards) they will nearly always be cheaper.
A typical equipment lease will be for 3-5 years and structured to have a $1 buy out at the end of the lease.
So, for example, if you obtained a set of equipment with a value of $15,000 and leased them for 5 years at 12.5% with a $1 buy out at the end, you could expect the payment to be about $335 per month. A really good lease might be $310 per month.
Not a great way to go if you have choices, but better than some others. Be sure you shop around for the leases, they are not all created equal. Your equipment supplier should be able to refer you. You bank should be able to as well.
