Estimating Costs
Filling in a budget is easy. Filling it in with numbers that turn out to be true is the whole game. Here's how to estimate costs like a line producer — real quotes over guesses, and honest padding for everything you can't yet know.
A budget is only as good as its numbers. Anyone can type figures into a template — the skill is typing figures that turn out to be true. That skill is estimating, and it's what separates a budget that holds up from one that blows up in week two. Here's how to estimate film costs like a line producer instead of guessing like an optimist.
Every estimate is quantity × unit × rate
Remember the atomic shape of a line item from Chapter 3: quantity × unit × rate. Every estimate you make is really three separate estimates hiding in one number:
- Quantity — how many? (How many shoot days, how many crew, how many weeks of rental.)
- Unit — measured in what? (Days, weeks, flat fee, per head.)
- Rate — how much per unit? (The day rate, the weekly rental price.)
Break every cost down this way and estimating gets far more accurate, because you can source each piece separately. You might know the rate cold but need to check the quantity against your schedule — or vice versa. Guessing a single lump-sum number ("camera... uh, $4,000?") is where budgets go wrong.
Quotes beat guesses — every time
The single biggest upgrade to your budget is replacing guesses with real quotes. For anything significant — camera package, insurance, a location, a key rental — actually ask. Email the rental house. Call the insurance broker. Get a number from someone who sells the thing. A real quote is worth ten educated guesses, and gathering them is most of what a line producer actually does.
Where to get real numbers
- Vendors and rental houses — for gear, equipment, and expendables. They quote gladly; it's a sales lead for them.
- Union/guild rate cards and local crew — for labor rates in your area (rates vary hugely by city and by union vs. non-union).
- Insurance brokers — for production insurance, which is easy to forget and not cheap.
- Other filmmakers — the fastest reality check. Someone who shot something similar near you knows the real numbers.
- Past budgets — your own or comparable films' actuals are gold. What things actually cost last time beats what they "should" cost.
When you can't get a quote, pad honestly
Some costs you genuinely can't nail down yet. For those, use a reasonable placeholder and round up, not down. Optimism is the enemy of budgeting — the natural human error is to under-estimate, so lean the other way on anything uncertain. This padding at the line-item level is different from your overall contingency (a whole chapter later); here it just means: when unsure, estimate high, and note that it's an estimate so you know which numbers are soft.
The budgets that hurt me weren't the ones with a big wrong number — those get caught. It was the death by a thousand optimistic little ones: "that'll be fine," "we'll figure out lunch," "the location's basically free." Each felt small; together they were a disaster by Friday of week one. So I made a rule: for every line I either have a real quote or I round up and flag it as a guess. When I open a budget now, I can see at a glance which numbers are solid and which are hopes. The solid ones I trust. The hopes I chase down before the money's committed. That habit has saved more shoots than any clever cost-cut ever did.
Estimating is the core craft of budgeting, and you'll use it on every line. Next we get specific about the biggest and trickiest area to estimate: labor — what crew actually costs, including the hidden costs on top of their rates.
