Find out whether your blog is paying you back. Enter what you spent to create the content, your monthly revenue and running costs, and the calculator shows your ROI over the period you choose, monthly profit, how many months it takes to earn back the investment, and what each post and each visitor is worth.

Estimate only. It assumes revenue and running costs stay at the monthly figures you entered; real blog income usually grows slowly as posts rank, and can drop with algorithm updates. Doesn’t include taxes or payment fees unless you add them to running costs.
Quick answer: Blog ROI = (revenue − total costs) ÷ total costs × 100, measured over a set period. Count the one-time cost of creating your posts plus running costs for the months you measure. A blog that cost $1,500 to build, earns $400 a month and costs $60 a month to run has spent $2,220 after a year and earned $4,800 — $2,580 profit and 116% ROI, with the $1,500 earned back in about 4.4 months.
A blog has two kinds of cost. The one-time investment is what you paid to create the content — you pay it once, and the posts keep earning. Running costs like hosting and tools come every month. Mixing them up is the most common mistake: comparing a whole content budget with one month’s revenue makes a blog look like a failure, and leaving out running costs makes it look better than it is.
So the calculator measures ROI over a period you choose, adds up every cost in that period, and separately shows how many months of profit it takes to earn back the one-time investment.
Revenue kept = monthly revenue × (1 − refund or reversal %)
Monthly profit = revenue kept − running costs − (your hours × your hourly value)
Total cost = one-time investment + (running costs + your time) × months
Net profit = revenue kept × months − total cost
ROI = net profit ÷ total cost × 100
Payback = one-time investment ÷ monthly profit (in months)
Profit margin = monthly profit ÷ revenue kept × 100
Revenue per 1,000 visitors = revenue kept ÷ visitors × 1,000
ROI shows how hard your money worked over the period. Payback shows how long until the content has paid for itself. A blog can have a weak 3-month ROI and a strong 24-month ROI from the same posts — choose the period that matches how you think about the investment.
| Result | What it means | How to use it |
|---|---|---|
| ROI over the period | Profit as a percentage of everything you spent in that period | Compare content batches, or the blog against other uses of the money |
| Months to earn back | How long the current monthly profit takes to cover the one-time investment | A shorter payback means less risk before the next content batch |
| Profit margin | Share of each month’s revenue left after running costs | Low margins mean tools and hosting are eating the income |
| Cost and revenue per post | Average spend and monthly earnings for each post | Revenue per post ÷ cost per post shows roughly how many months a typical post takes to pay off |
| Revenue per 1,000 visitors | How well each visit is monetised | If it’s low, improve affiliate placement or ads before buying more content |
If you write the posts yourself, the money ROI can look excellent because the biggest cost — your time — is missing. Add your monthly hours and what an hour of your time is worth in the optional box, and the calculator shows ROI with your time counted as a cost. Run it both ways: the money ROI tells you whether the blog pays its bills, and the time-included ROI tells you whether it pays you fairly.
| Input | Where to find it | Tip |
|---|---|---|
| One-time investment | Invoices from writers, editors and designers | Count one batch or one launch, not years of mixed spending. |
| Monthly revenue | Affiliate network dashboards, ad network reports, sponsor invoices | Average the last 3 months to smooth out one-off spikes. |
| Running costs | Card and PayPal statements | Spread yearly plans across 12 months. |
| Visitors | Google Analytics or your stats plugin | Use the same months as your revenue figure. |
$1,500 for 20 posts, $400 a month in revenue and $60 a month for hosting and tools. Monthly profit: $340. Over 12 months: $4,800 earned, $2,220 spent — $2,580 profit and 116.2% ROI. Payback: $1,500 ÷ $340 = 4.4 months. Each post cost $75 and earns $20 a month.
$800 for 10 freelance posts that bring $700 a month in commissions, with no extra running costs. Over 3 months: $2,100 earned against $800 — $1,300 profit and 162.5% ROI. Payback: 1.1 months, a strong case for ordering another batch.
No writer costs, $600 a month in revenue and $120 a month in tools. Counting money only, that’s $480 profit a month and 400% ROI over 12 months. But 40 hours a month valued at $15 an hour adds $600 of time, turning monthly profit into −$120 and 12-month ROI into −16.7%. The blog pays its bills but works out at about $12 an hour for your time, not $15.
$1,500 for 20 posts, only $50 a month so far and $40 a month in running costs. Monthly profit is $10, so payback would take 150 months at today’s income and the 12-month ROI is −69.7%. To earn the $1,500 back within a year the blog needs about $165 a month — a target to track as posts start ranking, not a reason to panic in month one.
Add up everything the blog cost over a period — the one-time content investment plus running costs for those months — and the revenue it earned in the same period. ROI = (revenue − total cost) ÷ total cost × 100. For example, $4,800 of revenue against $2,220 of costs is $2,580 profit, or 116% ROI.
There’s no single standard figure: it depends on your niche, how old the posts are and the period you measure. A positive ROI means the blog has paid back what you spent in that period. Compare your result with your own past batches and with other ways you could use the same money and time.
Content you pay for once keeps earning for months or years, while hosting and tools are paid every month. Treating a one-off content budget as a monthly cost makes ROI look far worse than it is, and leaving running costs out makes it look better.
It’s optional. Money-only ROI shows whether the blog covers its bills. Adding your hours and an hourly value shows whether it pays you fairly for your work. Many bloggers check both.
The number of months it takes your current monthly profit to cover the one-time content investment. If monthly profit is zero or negative, the investment isn’t being paid back yet.
No. It only changes the symbol shown. Enter all amounts in the same currency.
