For used-rig buyers

Every week your last line runs late costs you a figure you can see

The purchase price is the number you already know. What eats the deal is a repair, overhaul or upgrade line that lands after your contract start. This planner adds your price to every cost line you were quoted, runs each one on its own lead-time clock, and shows the all-in cost to the first day-rate from your own numbers.

What it does

A lead-time clock for every line

Each line gets your dollar figure, the day it starts after close and the lead time you were quoted. The planner shows each finish date and the earliest date all your lines complete, and names the line that sets it.

All-in cost to the first day-rate

Purchase price, your cost lines, your contingency and the financing carry from close to the first day-rate, added up and shown step by step.

What a week of delay costs you

Your daily financing carry plus the margin you forgo at your own day rate, operating cost and utilization, per day, per week, and against your contract start.

Break-even in earning days

How many earning days at your day rate less your operating cost it takes to cover the all-in figure, and the calendar days that means at your utilization.

What the clock looks like

Layout illustration using the app's labelled sample data. These are not quotes or lead times for any real rig; every figure in the planner is one you type in.

Line	Start day	Lead time	Finish date
Drawworks overhaul	14	75	2027-02-28
Top drive (order and install)	0	105	2027-03-16
Rig-up and commissioning	89	21	2027-03-21
Earliest date all your lines complete			2027-03-21

The planner holds no prices, no lead times and no rates. It does not look at the rig, does not check your quotes and does not tell you whether to buy. It does the arithmetic on the figures you enter, so you can read the cost of a slipped line before it happens.
