Stack Cost Calculator
Work out what a multi-compound stack actually costs per week, per month, and per cycle.
| Compound | Vial (mg) | Price / vial | Dose (mg) | ×/week | |
|---|---|---|---|---|---|
Fill in vial size, price, dose, and frequency for a row to see its cost.
Educational use only — not medical advice. Prices are entered by you and nothing leaves this browser (rows are stored in localStorage). Costs are linear estimates: monthly cost assumes a 52-week year (weeks × 52 ÷ 12), and cycle cost assumes every compound runs for the full cycle length at the stated weekly frequency.
About this tool
A multi-compound protocol is rarely priced as a stack — vials are bought one at a time, at different sizes and frequencies, so the real weekly burn is hard to see. The Stack Cost Calculator turns each compound's vial size, vial price, dose per administration, and weekly frequency into a cost per week, then rolls the whole stack into weekly, monthly, and full-cycle totals. Everything runs in your browser: the numbers you enter never leave your device, and rows are saved locally for your next visit.
How to use it
- 1 Add one row per compound: vial amount (mg), price per vial, dose per administration (mg), and administrations per week.
- 2 Read the per-compound panel: doses per vial, weeks per vial, and true cost per week.
- 3 Set your cycle length in weeks (default 8) — totals update with stack cost per week, per month, and per cycle.
- 4 Add or remove rows any time; entries persist in this browser automatically.
Frequently asked questions
How is cost per month calculated?
Monthly cost is total weekly cost multiplied by 52 and divided by 12 — an average month (4.33 weeks), not four weeks. That avoids understating the real recurring spend.
What if my dose is larger than one vial?
That row is excluded from totals — a vial yielding less than one full dose can't be costed per week. If you draw from multiple vials per administration, treat a "vial" as the total mg per purchase batch.
Is the price I enter stored or sent anywhere?
No. Everything is computed and stored locally in your browser's localStorage. Nothing is transmitted to any server, and clearing browser data removes the saved rows.
