People type this into search every day: hire vs diy cost calculator.
The usual answer is the materials receipt. That number is easy to add up. It leaves out the Saturday you spend on the job, and the second trip when the first coat fails.
The hire help vs DIY calculator prices both sides. DIY is materials plus hours times the value of your time, then a rework risk. Hire is the quote you typed. The cheaper label is the smaller of those two piles.
This page is a labeled example. It is not a contractor bid, and it is not a ruling on whether you should climb a ladder.
Materials, time, then a risk bump
The calculator uses:
(DIY materials + DIY hours × hour value) × (1 + rework risk)
Then it compares that economic cost with the professional quote. Results and safety are treated as equivalent. Specialist skill, permits, and warranty value stay out. Those are the tool’s assumptions.
Fig 1
Two piles, one cheaper label
Time and a rework buffer sit on the DIY side. The quote stands alone.
Add materials to hours times your hourly value. Raise that sum by the risk percent. Keep the smaller pile.
The tool prints a note on every result: hire a qualified professional for regulated or safety-critical work. The cheaper label is cash math. It is not a license check.
The CPSC home safety guides are about injuries in the house, not about saving $116. If the job is old paint, the EPA lead page is the rule, not the materials line. The home maintenance reserve post is the year after the job. This page is the job itself.
The hour value is a planning input. BLS employer compensation is one place to look up a loaded wage if you want that kind of number. The calculator default is $35. Type the figure that matches the hours you would give up.
Example 1: the published $966 DIY pile
Here are the calculator defaults:
- professional quote: $850
- DIY materials and rentals: $280
- DIY time: 16 hours
- value of your time: $35 / hour
- DIY rework risk: 15%
Time value: 16 × 35 = $560.00
Known DIY cost: 280 + 560 = $840.00
Rework buffer: 840 × 0.15 = $126.00
DIY economic cost: $966.00
Professional quote: $850.00
Difference: $116.00
The cheaper label is Hire help.

Calculator defaults. $35 an hour and a 15% rework buffer.
Time
$560
Materials
$280
Rework
$126
Time is $560, 58% of the $966 pile.
Materials are $280. The 15% buffer is $126.
The quote is $116 under that pile. People stare at the $280 materials line and call DIY cheaper. The hours are the larger slice.
Example 2: what if I change only the hourly value
Hold $850, $280, 16 hours, and 15% risk. Change the hour.
- $20 / hour: time $320. Known $600. DIY $690.00. Hire is $160 more. Label: DIY.
- $35 / hour (default): DIY $966.00. Label: Hire help.
- $50 / hour: time $800. Known $1,080. DIY $1,242.00. Hire is $392 cheaper.
The quote did not move. The hour did. $20 makes Saturday cheap enough that DIY wins. $50 makes the same Saturday more expensive than the crew.
The break-even hour sits between those two. Set DIY equal to $850:
(280 + 16 × hour) × 1.15 = 850
280 + 16 × hour = 739.13
hour = $28.70
At $28.70 the two piles match. A dollar above that, hire wins on this job.

|---|---|---|
| $20 / hr | $690 | $850 |
| $35 / hr | $966 | $850 |
| $50 / hr | $1.2k | $850 |
At $20 an hour DIY is $690.
The $35 default is $966. $50 an hour is $1,242.
The meeting cost post loads a salary into an hourly rate. Same idea, different room. If the hours on this job would otherwise be billed work, type that billed rate.
Example 3: what if I change only the hours
Hold $850, $280, $35, and 15%.
- 8 hours: time $280. Known $560. DIY $644.00. Hire is $206 more. Label: DIY.
- 16 hours (default): DIY $966.00. Label: Hire help.
- 24 hours: time $840. Known $1,120. DIY $1,288.00. Hire is $438 cheaper.
- 32 hours: time $1,120. Known $1,400. DIY $1,610.00. Hire is $760 cheaper.
The 8-hour path is a one-day job. The 32-hour path is four full days at $35. The materials line never moved.
Break-even hours, same formula:
(280 + hours × 35) × 1.15 = 850
hours = 13.12
Past about 13 hours at $35, the quote is cheaper on these defaults.

| Point | DIY |
|---|---|
| 8 hrs | $644 |
| 16 hrs | $966 |
| 24 hrs | $1.3k |

Eight hours print $644.
Sixteen hours are $966. Twenty-four are $1,288. Thirty-two are $1,610.
Example 4: the $280 mistake of ignoring time
Hold the default materials, hours, and quote. Set the hour value to $0 and the risk to 0%.
DIY economic cost: $280.00
Quote: $850.00
Difference: $570.00
The label flips to DIY. That is the materials receipt talking. Sixteen hours disappeared.
Leave the 15% risk and still price time at $0:
DIY: 280 × 1.15 = $322.00
Difference versus the quote: $528.00
Still DIY on the card. Still a Saturday you did not count.

The common mistake is this card. People compare $280 with $850 and stop. The default card puts $560 of time back in and the label changes.
Example 5: drop the rework buffer, or raise it
Hold $850, $280, 16 hours, and $35.
Risk 0%: known cost $840.00. DIY $840.00. Quote $850.00. Difference $10.00. Label: DIY.
Risk 15% (default): DIY $966.00. Label: Hire help.
Risk 25%: DIY 840 × 1.25 = $1,050.00. Difference $200.00. Label: Hire help.
Zero risk is a $10 win for DIY. That $10 is one extra hour at $35 if the first pass fails. The 15% default is the tool’s planning bump, not a measured failure rate. Type a higher percent when you have not done the job before.

Example 6: a $1,400 paint quote
A labeled interior paint job. Quote $1,400. Materials $220. Twelve hours. $35 an hour. 12% risk.
Time: 12 × 35 = $420.00
Known: 220 + 420 = $640.00
DIY: 640 × 1.12 = $716.80
Quote: $1,400.00
Difference: $683.20
Label: DIY.
The paint quantity post turns wall area into litres. This card prices the labor next to that can. The $220 is paint and tape. The $420 is the weekend. Even with a 12% bump, DIY is $683 under this quote.
EPA’s lead page still applies if the house is old enough. The cheaper label does not replace that rule.
Example 7: a fence Saturday versus a $2,400 deck
Fence, labeled: quote $1,800, materials $620, 20 hours, $28 an hour, 20% risk.
Time: 20 × 28 = $560.00
Known: 620 + 560 = $1,180.00
DIY: 1180 × 1.20 = $1,416.00
Difference: $384.00
Label: DIY.
A larger deck, labeled: quote $2,400, materials $900, 40 hours, $35 an hour, 15% risk.
Time: 40 × 35 = $1,400.00
Known: 900 + 1400 = $2,300.00
DIY: 2300 × 1.15 = $2,645.00
Difference: $245.00
Label: Hire help.
Forty hours at $35 already match most of the quote before the 15% bump. The fence still has room. The deck does not.

The renovation contingency default is labor $18,000, materials $12,000, permits $2,500, 8% tax, 15% contingency: $38,479.00. That is a project budget, not a hire-versus-DIY label. Use it when the job is already hired and you need a buffer on top.
Example 8: a $180 clean, and a cheaper $600 quote
Recurring clean, labeled: quote $180, supplies $25, 4 hours, $35 an hour, 10% risk.
Time: 4 × 35 = $140.00
Known: 25 + 140 = $165.00
DIY: 165 × 1.10 = $181.50
Difference: $1.50
Label: Hire help.
Four hours of your Saturday and $25 of supplies land $1.50 over the cleaner. The label is hire. The gap is a rounding of one coffee.
Drop the quote to $600 and keep the default DIY pile.
DIY stays $966.00
Quote: $600.00
Difference: $366.00
Label: Hire help.
A cheaper crew widens the gap. It does not change the DIY math.
The time-saved return tool asks a different question. Its default is a $1,200 setup, 12 hours saved a month at $45, $35 ongoing: payback 2.4 months. If you hire once and free the same hours every month, that is the card. This page is one job.
Example 9: the electrical quote the math likes and the tool still flags
Labeled electrical work: quote $950, materials $180, 6 hours, $45 an hour, 30% risk.
Time: 6 × 45 = $270.00
Known: 180 + 270 = $450.00
DIY: 450 × 1.30 = $585.00
Difference: $365.00
Label: DIY.
The card says DIY is cheaper. The tool still prints the safety note. Permits and warranty stay out of both piles. A $365 gap is not a license. Type the quote, read the note, and stop if the work is regulated.

The paint and fence jobs come in under the quote.
The default and the deck come in over it.
A move has the same shape: known costs, then a buffer. The moving default is $3,120 plus 10% = $3,432.00. DIY on a move is the same formula with a truck and your Saturday.

Open the hire help vs DIY calculator with the quote on the table and the hours you would spend. If the work is electrical, gas, or lead paint, the cheaper label is not the decision. If the work is shelves, type the hour you would otherwise bill and look at the $116 gap again.
