Finance Calculators & Templates Pack

What this pack includes

A set of four compact, practical calculators designed for one‑person and very small businesses. Each tool is focused on a common decision entrepreneurs face and presented so you can get a useful answer in minutes.

• Pricing & Margin Calculator — turn costs into a price or check your margin on an existing price.
• Break‑Even (hours / months) — how many billable hours or months at a given price you need to cover fixed costs.
• Project vs Retainer Comparator — compare effective rates, revenue timing, and risk between a one‑off project and an ongoing retainer.
• Cash Runway Calculator with Scenarios — estimate how many months you can operate at different burn rates and test simple scenario adjustments.

How to use these tools

Pick the calculator that matches your immediate question, gather the few numbers called out in each tool (costs, rates, monthly fixed costs, current cash), and plug them in. Each tool is intentionally simple so you get a clear, actionable number rather than a complicated forecast you won't use.

Use them to answer practical questions such as:

• Am I charging enough for this service?
• How many billable hours must I sell to cover rent and basic living costs?
• Would a monthly retainer improve my effective hourly rate and reduce risk?
• If sales drop 20% this quarter, how many months of runway do I have?

Calculator details, inputs, and quick examples

1. Pricing & Margin Calculator

Purpose: Convert true cost into a price target or check the margin of an existing price.

Inputs: cost per unit or cost per hour (all direct costs and allocated overhead you want to include), desired margin % OR existing price.

Outputs: suggested price for a target margin or gross margin % for the given price.

Formula examples:

• Price = Cost / (1 - Margin%) (when you want a target margin)
• Margin% = (Price - Cost) / Price

Example: cost = $50, desired margin = 40% → Price = 50 / (1 - 0.4) = $83.33

2. Break‑Even in Hours / Months

Purpose: Find how many billable hours or months at a given price you need to cover your fixed costs.

Inputs: fixed monthly costs, price per hour (or price per month), variable cost per hour (if applicable).

Output: break‑even hours per month (or months).

Formula example (hourly model): Break‑even hours = Fixed costs / (Price per hour - Variable cost per hour)

Example: fixed costs = $3,000 / month, price = $75/hr, variable cost = $10/hr → BE hours = 3000 / (75 - 10) ≈ 47 hours/month

3. Project vs Retainer Comparator

Purpose: Compare a one‑off project fee to a retainer in terms of revenue, effective hourly rate, and cash timing risk.

Inputs: project fee, estimated hours for project, proposed monthly retainer, expected months the retainer runs, expected monthly hours under retainer.

Outputs: effective hourly rate for each option, total revenue over a defined period, and a simple risk/benefit note (e.g., steady cash vs larger up‑front payment but irregular work).

Example: project fee $5,000, estimated 60 hours → $83/hr. Retainer $1,500/month for 6 months at 20 hours/month → effective rate = 1500 / 20 = $75/hr, revenue = $9,000 over 6 months.

4. Cash Runway Calculator with Scenarios

Purpose: Estimate how many months your current cash will last under a given burn rate and quickly compare a few simple scenarios (base, cautious, optimistic).

Inputs: current cash balance, average monthly revenue, average monthly expenses (or monthly net burn). Optional scenario adjustments as a percentage (e.g., -20% revenue, +10% cost).

Output: runway in months for the base case and adjusted scenarios.

Formula: Runway months = Current cash / Net monthly burn (where net monthly burn = Expenses - Revenue; if revenue > expenses runway is indefinite for the period modeled)

Example: cash $20,000, revenue $4,000, expenses $6,000 → burn $2,000/month → runway 10 months. If revenue falls 25% → revenue $3,000 → burn $3,000 → runway ≈ 6.7 months.

Practical tips and assumptions

• Keep your inputs simple and consistent — be clear whether numbers are monthly, per hour, or per project.
• Include the costs you often forget: software subscriptions, taxes you must set aside, modest savings for slow periods, and a simple allocation for non‑billable time.
• Use conservative scenario adjustments (e.g., -10% to -30%) to see how fragile or robust your runway and pricing are.
• These calculators are small decision tools, not full financial forecasts. They help you compare options and make faster trade‑off decisions.

Next steps

1) Try the calculator matching your most urgent question (pricing, break‑even, project vs retainer, or runway). 2) Record your assumptions so you can update them and learn over time. 3) If the numbers show risk, run simple experiments: increase price on a small offer, test a short retainer with one client, or cut nonessential monthly costs and measure the effect.

If you want these tools to save scenarios, compute results automatically, or integrate with your accounting data, consider the interactive version described in the Capability Notes below.
