Reviews

Why people pay once.

Pro for the browser. Templates for the file. Here’s what they said after.

Snowball vs Avalanche on the same debts. I picked the date I could live with, then bought the spreadsheet so I could log the extra $200.

Paying off six debts·Debt Payoff

The calculator got me in. The paycheck workbook is what I still open. Bills hit the right check. I don’t argue with it.

Chris L.

Uses the spreadsheet every payday·Paycheck spreadsheet

I saved a $100-extra plan and a $200-extra plan and emailed myself both. Nineteen dollars, once. I would have paid that for the comparison table alone.

Questions

Do I need an account?
No password. Calculators are free. After you pay, use the email from your Stripe receipt on the Restore page to bring Pro or templates to another device.
Is this a subscription?
No. Everything is one-time.
Does Pro include the spreadsheets?
No. Pro is for the web tools (save, export, comparison). Spreadsheets are the Excel / Google Sheets files. Buy one template, the bundle, or both Pro and a template — they stack.
What’s the difference vs the spreadsheet?
The web tools are the 2-minute version, free. The workbooks add logs, due-date bills, 120-month engines, and the tabs you live in every month.

Template and Pro purchases go through Stripe Checkout. Harbor Pro is $19 once and does not include the spreadsheet files. See Privacy and Terms.
