Your Pocket Project Manager: How One Free Toolkit Replaces Five Trips to the Lumber Yard
Fifteen calculators, one free account, and a blog full of know-how — here's how BuildPlan turns your phone into the project manager you always wished you had.
The Five-Trip Weekend (and How to End It)
You know the pattern. Saturday morning: the lumber yard. Saturday afternoon: the home center, because the lumber yard didn't have enough concrete. Sunday morning: back to the home center for the paint you forgot. Sunday afternoon: the hardware store for the screws that weren't in the box. By Sunday night you've spent more on gas than on the project.
Every one of those trips is a math problem you solved too late. BuildPlan exists to solve them before you leave the house.
Fifteen Calculators, Four Categories
BuildPlan is a hub of 15 specialized calculators, each on its own page, each answering a complete project-planning question — not just "how much," but how much with waste, and what does it cost at my prices.
🏗️ Building Materials
- Concrete Slab — cubic yards, bags, ready-mix
- Drywall — sheets, compound, screws, tape
- Gravel — cubic yards, tons, cost
- Mulch — cubic yards, bags, cost
🏡 Exterior Projects
- Roofing Squares — bundles, underlayment, nails
- Roof Pitch — ratio, angle, rafter length
- Fence Materials — posts, rails, pickets, concrete
- Deck Boards — boards, joists, posts, hardware
🛋️ Interior Projects
⚡ Home Systems
- HVAC BTU — cooling load, tonnage
- Pipe Volume — gallons, liters, flow
- Water Pressure — PSI from head height
- Electrical Load — amps, watts, circuits
Bring Your Own Prices
Here's the part that makes BuildPlan different from every other calculator site: you enter your own local material prices. National averages are useless when your lumber yard charges 30% more than the big-box store two towns over. Every BuildPlan calculator has a price field, so the cost estimate reflects your supplier, not a number from 2019.
Save, Print, Share — Free
Create a free account and you unlock three things that turn a calculator into a project manager:
- Save — every calculation can be saved with a project name ("Garage Slab," "Backyard Fence," "Kitchen Refresh") and revisited anytime on your Saved Calculations page.
- Print — one click formats a clean, professional materials list you can hand to a contractor or take to the store.
- Share — send the result link to your spouse, your builder, or your dad who "just wants to double-check your math."
No credit card. No trial. The calculators are free, the account is free, and the only thing you ever pay for is the materials you buy with the numbers we give you.
The Blog: Know-How, Not Just Numbers
A calculator tells you how much. The BuildPlan blog tells you how — and why. We cover the patterns that tie projects together (bulk materials, area-and-waste, system sizing), the safety disclaimers that keep you out of the ER, and the planning tips that turn a weekend disaster into a weekend win.
This post you're reading is part of it. Bookmark the blog and check back — we publish practical, no-fluff guides for homeowners and contractors who'd rather measure twice.
One Toolkit, Zero Guesswork
You don't need five apps, three spreadsheets, and a notebook full of envelopes. You need one hub that does the math, remembers your projects, and prints a clean list. That's BuildPlan — your pocket project manager, free forever.
Start with a calculator, save your first project, and make this the weekend you only go to the lumber yard once.
