Complete ToolPatch tools directory
ToolPatch is a growing collection of focused utilities and practical workflow toolkits. Each page handles one task with clear inputs, fast results, and usable outputs.
Toolkits for common workflows
Start with a workflow when the job spans several small tools, assumptions, or handoff steps.
Startup Unit Economics Toolkit
Build, stress-test, and communicate your core economics in one workflow.
Network Troubleshooting Toolkit
Diagnose addressing, DNS, and transport bottlenecks quickly.
Lab and Chemistry Calculations Toolkit
Plan solution preparation, dilution, gas-law, reaction-yield, and pH checks with visible chemistry assumptions.
Project Delivery Planning Toolkit
Forecast schedule and delivery risk using practical PM metrics.
Engineering Field Calcs Toolkit
Fast first-pass engineering calculations for site and workshop decisions.
Chart Generators Toolkit
Choose the right chart generator for radar, spider, radial, Gantt, Sankey, bubble, Pareto, funnel, waterfall, trend, comparison, and distribution views.
Marine Navigation Calculators Toolkit
Use practical marine navigation calculators for CPA/TCPA, under-keel clearance, tide windows, route distance, set and drift, fuel range, ETA, anchoring, COLREGs encounter checks, and vessel turning estimates.

Planning & Productivity
Age Calculator
Calculate age in years, days, and weeks from birth date.
Simple date-based age computation for personal and admin use.
Planning & Productivity
Burndown Forecast Calculator
Forecast sprint completion date from current burn rate.
Estimate whether your sprint is on track and what burn rate is needed to finish remaining scope on time.
Planning & Productivity
Date Difference Calculator
Calculate days and weeks between two dates.
Useful for planning timelines, deadlines, and scheduling windows.
Planning & Productivity
Dependency Risk Heatmap
Quantify dependency risk from blocked items, ownership clarity, and complexity.
Score external/internal dependency risk to identify where delivery bottlenecks are most likely to impact timeline.
Planning & Productivity
Earned Value Calculator
Calculate CPI, SPI, CV, and EAC for schedule/cost control.
Apply earned value management formulas to detect budget and schedule drift early.
Planning & Productivity
Meeting Cost Calculator
Estimate meeting cost per session, week, month, and year.
Translate meeting load into direct labor cost to improve planning discipline and reduce unnecessary meetings.
Planning & Productivity
Milestone Slip Calculator
Measure schedule slip based on planned vs actual milestone progress.
Estimate slip percentage, projected delay days, and forecasted delivery date from milestone execution pace.
Planning & Productivity
PTO Accrual Calculator
Calculate accrued and remaining paid time off based on annual allowance.
Estimate earned PTO from annual policy, months worked, and used days. Helpful for HR operations and employee leave planning.
Planning & Productivity
Resource Allocation Planner
Balance workload against team capacity using time and utilization assumptions.
Plan team allocation by comparing total work hours against available capacity and required team size.
Planning & Productivity
Risk Matrix Scorer
Score project risks using probability, impact, and expected loss.
Apply a standard 5x5 risk matrix with expected financial exposure to prioritize mitigation efforts.
Planning & Productivity
Scope Creep Detector
Detect scope growth risk and delivery pressure before deadlines are missed.
Compare initial and current scope, then estimate the throughput increase needed to still finish on plan.
Planning & Productivity
Sprint Capacity Calculator
Estimate sprint hours and suggested story points from team constraints.
Compute gross, net, and effective sprint capacity after ceremonies, then estimate practical story point target.
Planning & Productivity
Velocity Stability Index
Analyze sprint velocity consistency with a normalized stability index.
Convert historical sprint velocities into variance, coefficient of variation, and a stability score for release planning confidence.
Planning & Productivity
Zodiac Birth Chart Calculator
Estimate Sun, Moon, Rising, and Midheaven signs from birth data.
Generate a quick tropical astrology summary from birth date, local time, and place. The tool estimates Sun sign, Moon sign, Ascendant (rising sign), and Midheaven using astronomical approximations. It supports city presets and manual latitude/longitude overrides for better rising-sign accuracy. Use it for quick orientation, profile enrichment, or content personalization workflows where you need practical outputs on one page. This is not a full professional natal chart engine; results are approximate and intended for educational or lifestyle use.
