Employees get a paycheck that keeps arriving on vacation. Freelancers get silence — no billing, no deposit, and the bills that were already on autopay keep firing anyway. That gap is the single biggest reason so many self-employed people quietly skip the time off they've earned: not because they don't want it, but because nobody ever put a number on what it costs. This calculator does that math for you, combining the income you won't bill with the fixed costs that don't take a vacation, so you can save for the trip on purpose instead of feeling it as a surprise dip in your bank balance when you get back.
How it works
The calculator adds up two separate costs of time away from work. The first is lost income: your day rate multiplied by the number of days you're off. If you'd normally bill $400 a day and you take ten days, that's $4,000 you simply won't invoice — not a penalty, just work that didn't happen.
The second is continuing costs: the fixed expenses that keep charging you whether you're working or lounging on a beach — software subscriptions, coworking rent, business insurance, a loan payment. The calculator prorates your fixed monthly costs across the days you're gone, using 21.75 as the average number of working days in a month, so a longer trip carries proportionally more of that monthly bill. Add lost income and continuing costs together and you get the total cost of the time off — the real number a week away from your desk carries, not just the obvious half of it.
Finally, the calculator divides that total by 12 to suggest a flat monthly savings amount. Save that much every month and one trip of this size is already funded before you book it, the same way you'd budget for taxes or insurance instead of scrambling for cash at the last minute.
Worked example
Say your day rate is $400, you're planning 10 days off, and you have $0 in fixed monthly costs to worry about (a lean setup with no rent or retainer bills).
- Lost income: $400 × 10 = $4,000
- Continuing costs: $0 × (10 ÷ 21.75) = $0
- Total cost: $4,000 + $0 = $4,000
- Suggested monthly savings: $4,000 ÷ 12 = $333.33
Now suppose you're not quite that lean — say you're paying $800 a month for a coworking desk, project management software, and business insurance combined, and you're taking 14 days instead of 10 at a $500 day rate. Lost income climbs to $7,000, and continuing costs add another $514.94 (that's $800 prorated across 14 of the 21.75 average working days in a month), for a total cost of $7,514.94 and a suggested monthly savings of $626.25. The fixed-cost piece isn't trivial — it's often the part freelancers forget to count at all.
How to interpret your result
The total cost is what a break this size actually takes out of your business, not a warning to never take one. Freelancing without any time off isn't sustainable either — it's simply a cost that needs to be planned for instead of discovered after the fact. Treat the number the way you'd treat a tax bill: known in advance, saved for in advance, and not a crisis when it arrives.
The suggested monthly savings figure is a starting point, not a mandate. It assumes you're funding one trip of this size once a year — if you take multiple breaks, or a much longer one, scale the savings target accordingly. And if the total looks larger than expected, that's useful information too: it might mean your day rate needs to go up, or that some of those "fixed" monthly costs are worth reconsidering, rather than that vacation itself is the problem.
Methodology & sources
The formula is lostIncome = dayRate × daysOff, continuingCosts = fixedMonthlyCosts × (daysOff ÷ 21.75), totalCost = lostIncome + continuingCosts, and suggestedMonthlySavings = totalCost ÷ 12. The 21.75 figure is a standard approximation for average working days per month (5 weekdays × 52 weeks ÷ 12 months ≈ 21.7), used here to prorate a monthly cost across a shorter stretch of days off. Every output is rounded from unrounded intermediate math, so the pieces stay internally consistent with the total.
The underlying idea — that freelancers should price and budget for time off in advance rather than treat it as unpaid loss — is a recurring theme in freelance-industry advice; the Freelancers Union's guide to taking vacation as a freelancer makes the same point directly: your rates and savings habits should already be accounting for the time you plan to take off, so a vacation doesn't have to compete with rent for the same dollar.
