Why calculate your own schedule

Lenders quote a monthly payment and a term. The real story — how much interest you pay, how fast you build equity, and how small changes save years — only shows up when you run the numbers yourself.

Know your true cost

Every payment broken into interest and principal, so you see exactly what the loan really costs — not just the monthly number.

Model prepayments

Add extra monthly payments or one-time lump sums and instantly watch years and interest disappear from your schedule.

Handle real-world terms

Interest-only periods, balloon payments, seasonal schedules, and rate changes — describe them in a note and AI builds the schedule.

Any payment frequency

Weekly, bi-weekly, semi-monthly, monthly, semi-annual, or annual — switch frequencies and compare what each costs.

Export your plan

Download a clean PDF or CSV of the full schedule for your records, your accountant, or your advisor.

Private by default

Your loans are yours alone. Every schedule stays tied to your account — no shared lists, no public data.

What people say

“I shaved four years off my mortgage by testing extra payments here. The AI note for my seasonal payments matched my exact situation — something no other tool could do.”
Mara K. · Homeowner, Calgary
“Finally a tool that handles interest-only periods and balloons without a spreadsheet. The CSV export made sharing the plan with my advisor trivial.”
Devon R. · Real-estate investor
“Clear, fast, and honest about interest. For the first time I actually understand where every dollar of my loan is going.”
Priya S. · First-time buyer
