Read the introduction
Before you buy another phone, check what you’ll pay to keep it useful.
I’m Evan, your presenter at The Phone Tax.
We look beyond the sticker price: software support, battery condition, repair costs, and the terms hidden inside a tempting deal.
The guides turn that research into questions to ask and worksheets you can actually use.
Buying new? Start with Budget Vault.
Buying used or refurbished? Choose Used Without Getting Burned.
Still deciding whether to keep, repair, or replace? The complete system brings those options together.
These are printable, fillable PDFs. Add your own prices, check the assumptions, and compare options over the time you expect to keep your phone. You do the calculations yourself.
Start with the free six-question checklist. No email required.
