Bid economics calculator
Tell us how many tenders you do. We'll show you the time and money you'll save, how much more profit you'd make if you won a few more, and the one number your finance director will ask for — how fast it pays back.
Tell us about your bidding
60% isn't a guess — it's arithmetic. A bid splits roughly into research (30%), writing (40%) and review (30%); each stage shrinks, and on conservative cuts they compound to ~60%. Full workings below. Drop it to 40% for a cautious case; 30% still pays back.

For 2 bids a month at a 20% win rate and a 10% net margin, the Core plan saves you £64,800 a year on bid time, adds £7,200 a year in net margin from submitting 10% more bids, costs £5,940 a year, and pays for itself in

How credits work
Behind the headline question count, every plan runs on one monthly pool of credits— the single way we measure usage. Drafting an answer, researching a buyer, live scoring, pre-submission checks and pulling evidence out of your documents all draw from the same pool. Heavier jobs cost a little more, light ones less. You're never billed separately for the supporting steps — they come out of the one pool, so you can see exactly where every credit goes inside the app.
What each action costs
Live answer scoring is included as you draft — no separate charge.

The certain half — time + money you save
You can prove this on day one. Less time writing bids, fewer panicked weekends, lower cost per submission.
Your input above: each bid takes 60% less time once the platform is doing the heavy lifting. Full workings below.
The optimistic half — extra wins, extra profit
You decide how much your win rate goes up. We show the profit you keep from those extra wins, not the headline contract value.
Win rate, contract size and net margin live in the inputs at the top of the page. This slider is just the "what if" — how much you think the platform pushes your win rate up.
Three scenarios — how soon you break even

How we worked it out — and what we're not promising
Why bids take less time
Take a 60-hour bid. It splits roughly into research (~30% = 18h), writing (~40% = 24h — about 7,200 finished words at a realistic 300 words/hour) and review/Q&A (~30% = 18h). Each stage shrinks: research drops as BidIntel profiles the buyer in minutes not days; writing drops because you edit a cited first draft instead of starting from a blank page; review drops because scoring runs against a stored rubric in minutes, not a day of internal QA. Even on cautious per-stage cuts — research −70%, writing −50%, review −65% — that's ~36 of 60 hours back, i.e. ~60%. Dial it down to 40% or 30% in the calculator and it still pays back. Check it against your first three bids before relying on it.
Why we don't pick your win rate
We won't tell you your win rate will jump. The headline answer at the top doesn't assume any win-rate change at all — only time saved + 10% more bids. The slider below the answer is for you to test what happens if your win rate goes up, but it doesn't influence the headline.
Profit, not contract value
Winning a £100k contract doesn't put £100k in your pocket. We multiply extra wins by the profit margin you told us — so the number on screen is real money you'd keep.
Where the platform cost comes from
Whichever plan you pick above drives this — right now that's Core at £495/month (£5,940 a year). Real published price, not a teaser. Full ladder shown below.
What we deliberately leave out
We don't count the one-off ~10–20 hours to load your existing evidence in, or the way the platform gets sharper for you over time. Both make the real return better than what's shown — we left them out to keep the maths cautious.
