Investor Update Template: What a Monthly Update Should Include

An investor update template gives you the same structure every month, so investors can read your numbers fast and compare them with last month without hunting. Most templates that rank today list the usual sections, such as highlights, KPIs and asks, and stop there. This guide adds the parts they skip: the exact formulas for cash, burn and runway, the SaaS metrics to report against plan, a worked example, and what to change when runway gets short.

What Should a Monthly Investor Update Include?

Investors read an update to answer three questions. How is the business doing? How long will the cash last? How can they help? Seven sections cover all three. Keep them in the same order every month so readers know exactly where to look.

Aim for something a busy investor can read in about five minutes, roughly 400 to 700 words plus two small tables. Put the TL;DR and the numbers block at the top. An investor who stops reading after ten lines should still know whether you are on plan and when the cash runs out.

Leave out long roadmaps, press mentions with no effect on revenue, and vanity counts like signups without activation. Also skip anything you would mind seeing forwarded, because updates travel.

How Do You Calculate the Numbers Block?

Founders lose credibility here more than anywhere else. Someone counts receivables as cash one month, switches burn methods the next, and the runway figure jumps for no real reason. Pick one method per line, print the definitions once at the bottom of the update, and keep them fixed. If you must change a definition, say so and restate the prior month.

1. Cash. Take the bank balance on the last day of the month. Leave out receivables, undrawn credit lines and money investors have promised but not wired.
2. Gross burn. Add up all cash operating expenses paid in the month: payroll, rent, software, contractors and marketing.
3. Net burn. Subtract cash collected from customers from cash paid out. This equals the drop in your bank balance once you exclude equity and loan proceeds.
4. Average net burn. Average the last three months of net burn so one annual software bill or a late customer payment does not swing the figure.
5. Runway. Divide cash by average net burn. State the method next to the number.
6. Cash-zero date. Name the month your forecast hits zero, with your hiring plan and committed spend included. This date often lands sooner than simple runway suggests, because burn rises as new people join.
7. Default alive check. Apply Paul Graham's test: if expenses stay flat and revenue keeps growing at its recent rate, do you reach profitability on the cash you have? Write yes or no.

My take: I measure burn on the average of the last three months, never one month. I also count the bank balance only. Receivables and unsigned term sheets are not cash, and investors discount any runway that includes them.

The simple formula hides problems when burn is climbing, so read how to calculate startup runway before you lock in a method. If your model pulls monthly actuals straight from your accounting system, the numbers block matches your books every month without a manual rebuild.

Which SaaS Metrics Belong in the Update?

Report five to seven metrics, the same ones every month. For a SaaS company, these carry the most signal:

• MRR and ARR. ARR equals MRR times 12.
• Net new MRR. New plus expansion, minus contraction, minus churned MRR. Show all four parts so investors see whether growth comes from sales or from existing customers.
• Net revenue retention (NRR). Starting MRR from a group of customers, plus expansion, minus contraction and churn, divided by starting MRR, measured over 12 months.
• Gross churn. Revenue lost to cancellations and downgrades, before any expansion.
• Burn multiple. Net burn divided by net new ARR over the same period. Lower is better. See what counts as a good burn multiple for bands and fixes.
• CAC payback. Months of gross profit needed to recover the cost of acquiring a customer.
• Gross margin. Revenue minus cost of revenue, divided by revenue.

Show each metric against plan as well as against last month. A month-over-month gain looks fine until investors see you planned twice as much. The plan column also tells them whether your forecast deserves trust when you raise.

When you add context, compare yourself with companies in your ARR band. BurnRateIQ's benchmark library draws on the Benchmarkit 2025 B2B SaaS Performance Metrics report, which puts median annual ARR growth at 100% for companies under $1M ARR, 45% for $1M to $5M, and 27% for $5M to $20M, against 26% across all companies. A company at $800k ARR growing 60% beats the overall median but sits well below its own band.

Funding source matters too. The SaaS Capital 2026 Private B2B SaaS Company Growth Rate Benchmarks, also in BurnRateIQ's library, put median annual ARR growth at 22% across all companies, 25% for equity-backed companies and 20% for bootstrapped ones. If you quote a growth benchmark in your update, name the survey and the peer group.

The table below shows the quartiles BurnRateIQ uses for peer comparisons, from Benchmarkit 2025, and the SaaS Capital 2025 B2B SaaS Retention Benchmarks agrees on a 101% median NRR. Check definitions before you quote a figure: SaaS Capital reports a 9% median annual gross churn and Benchmarkit reports 12%, so name the source you compare against.

For retention and margin by band, see SaaS benchmarks by ARR.

Example: Fieldnote's September 2026 Investor Update

Fieldnote is a fictional seed-stage SaaS company selling scheduling software to field service teams. It sends updates in the first week of each month. Here is a condensed version of its September update.

TL;DR

• Signed our largest customer to date at $2,000 MRR.
• Missed the MRR plan by $3,000 because two mid-size deals slipped to October.
• Cash-zero date: November 2027 on the current hiring plan. Default alive: no.

Numbers block (cash basis, three-month average net burn)

Average net burn is $117,333, so runway is $1,840,000 ÷ $117,333 = 15.7 months. Two engineers start in November and January, which lifts net burn toward $145,000 by early 2027. The forecast therefore hits zero in November 2027, about two months sooner than simple runway suggests.

Metrics vs plan

Net new MRR breaks down as $5,200 new, $1,100 expansion, $400 contraction and $2,400 churned. For the quarter, Fieldnote burned $352,000 and added $120,000 in net new ARR as MRR grew from $62,000 to $72,000, so the burn multiple is 2.9x. ARR of $864,000 grew 111% from $410,000 a year ago, slightly above the 100% median for its band in BurnRateIQ's benchmark data from Benchmarkit.

Asks

1. Intros to operations leaders at HVAC or plumbing companies with 50 to 300 technicians. A forwardable blurb is below.
2. A referral for a senior backend engineer with routing experience, starting by January.
3. Thirty minutes with anyone who has priced a usage-based add-on for small business customers.

How Do You Share Bad News or Short Runway?

Put bad news in the TL;DR at the top. Investors forgive a miss. They lose trust when they find it themselves. Use the same four parts every time:

1. State the number and the gap to plan.
2. Name the cause in one sentence.
3. Say what you changed.
4. Give the new date or target.

When runway drops below about 12 months, add three lines to the numbers block. Show fundraising status (who you are talking to and at what stage), the cash-zero date, and the fallback plan if the raise slips: which costs you would cut, how much they save per month, and the new cash-zero date after cuts. That fallback line shows investors you have already done the math.

My take: The cash-zero date from your forecast matters more than today's runway, because your hiring plan is already spending future months. Start raising with about 12 months of runway left. Under 6 months, cut costs first, then raise.

If you are profitable, say so plainly. A runway figure of 80 months tells investors less than the word profitable.

How to Write Asks Investors Can Act On

Vague asks get ignored. Each ask should name a person type, a company type and a deadline, and make the next step easy. Keep it to two or three asks per update.

Include a short blurb investors can forward without editing. In the next update, thank by name the people who helped and report what came of their intro. That loop makes your next ask easier to answer.

How Often Should You Send It, and in What Format?

Send monthly from your first check through Series A. After a Series A and a formal board, many companies move to every other month or quarterly, with board decks carrying the detail. Monthly costs little once the template is fixed, because the numbers block refreshes from your books.

Send within the first ten days of the following month, in the body of a plain email. Use a subject line with your company name and period, such as Fieldnote September 2026 Investor Update, so investors can search for it later. Link your financial model or attach a PDF of the tables for anyone who wants detail. A model with live formulas lets investors check your math, so pull the numbers block from the same file every month.

Prospective investors can get a shorter version: the TL;DR, wins and two or three headline metrics. Keep the full cash and burn detail for people already on your cap table. Tools range from a mail merge to an email platform or an investor CRM. Pick the one that keeps your list and send history in one place.

If you want the numbers block, metrics against plan and cash-zero date to fill themselves in each month, BurnRateIQ builds them from Xero, Zoho Books or FreshBooks, or from six quick questions.
