Real problems, worked end to end

Each template is a ready-made model that answers a specific question — load it into Sortia with one click, then change the assumptions to fit your situation. Every figure shown is computed by the actual tool.

Finance Startup Runway & Cash-Out Date A single-number runway hides the truth: burn and growth are uncertain, so your cash-out date is a range. This template runs thousands of 24-month scenarios and shows the real spread — and your odds of surviving the year. See the worked example → Finance DCF Valuation with Monte Carlo A DCF is hostage to three guessed inputs. Change growth, margin, or WACC a little and the value swings a lot. This template runs all three as ranges and returns a valuation distribution, not one brittle number. See the worked example → SaaS SaaS ARR Forecast with Uncertainty A single forecast line is a guess dressed up as a fact. New bookings, churn, and expansion all vary month to month. This template turns your forecast into a confidence cone and your odds of clearing target. See the worked example → Finance Funding Round Dilution & Exit Waterfall The cap table is deterministic — the exit is not. This template runs the exit value as a range through a 1× liquidation waterfall, so you see the distribution of your real take-home, not a single optimistic headline. See the worked example → Operations Inventory Order Quantity (Newsvendor) Stock out and you lose the sale; over-order and it costs you. This classic newsvendor template shows your profit distribution at a given order quantity — then optimizes the quantity that maximizes expected profit. See the worked example → Life Job Offer: Counter or Accept? Countering feels risky, but "risky" is a feeling, not a number. Lay out the odds — they agree, they hold firm, or (rarely) it sours — and Sortia rolls the tree back to the expected value of each choice, so you negotiate with the math in front of you. See the worked example → School What Grade Will You Get? Homework and the midterm are locked in; the final is the unknown. This template runs the final as a range through your weighted grade, so you see the spread of grades you might land — and exactly what you need on the final to reach the next letter. See the worked example → Life Will the Event Go Over Budget? The final guest count, the per-head cost, the "miscellaneous" line — none are fixed until the day. This template runs them all as ranges and shows what the event might actually cost, and the odds you go over the number you had in mind. See the worked example → Home Home Renovation: True Cost Renovations run over — that is not pessimism, it is history. This template models the overrun and the odds of hidden surprises so you can budget the number you will actually spend, not the number on the quote. See the worked example → Personal Finance Will You Hit Your Savings Goal? Some months you save more, some less; returns bounce around. A single "if I save $700 a month…" line ignores all of that. This template projects your balance over three years with the wobble built in — and shows your real odds of reaching the goal. See the worked example → Health Cheapest Meal Plan (Optimization) This is the classic "diet problem" — pick servings of each food to hit your nutrition targets for the least money. There are infinitely many combinations; a linear program finds the single cheapest one exactly, in one solve. See the worked example → Marketing Split a Budget for Best Return Pour everything into your best channel and returns flatten out; spread too thin and you waste it. Because each channel has diminishing returns, a fixed budget has a real optimum — and it is not obvious. The nonlinear optimizer finds it. See the worked example → School What Do You Need on the Final? You know your homework and midterm; you know the weights. So there is one exact score on the final that gets you the grade you want. Goal Seek runs the formula backwards and hands it to you. See the worked example → Work Will the Project Finish on Time? Real projects do not progress in a straight line — they ramp up, cruise, and crawl to the finish. Feed in your progress so far and the S-curve fits that natural shape and extends it to 100%, so your finish date accounts for the slow tail everyone underestimates. See the worked example → Analytics What Actually Drives Your Sales? Everyone has a theory about what drives the numbers. Regression settles it: it measures how much each factor moves your outcome, and puts a p-value on each so you know which effects are real and which are noise. See the worked example →
