01
Assumptions should not disappear into rows.
Every calculator keeps the variables that shape a conclusion close to the result they create.

Financial calculators for decisions that need to hold up
Make the numbers
answer back.
mittafin gives valuation, return, financing, and operating questions a calmer working surface. Start with clear assumptions. See the result. Keep the reasoning in view.
Mittafin is pronounced MIT-ta-fin. It starts with Finnish mitta, meaning measure, then anchors it in finance.

The working problem
Good judgment needs a
better place to begin.
02
One number is rarely the whole answer.
Move from the headline metric into forecasts, schedules, and compositions without losing context.
03
Financial tools can be dense without being difficult.
Compact fields, quiet structure, and deliberate hierarchy leave room for the actual decision.
How it works

question to clarity.
- 01

- 02
Set the assumptions.
Work through a focused set of inputs with the units and terms in view.
- 03
Read the full signal.
Use the result, then follow it into the schedule or method that explains it.

Methodology proof
Methodology you can inspect before you trust the output.
mittafin keeps methodology visible across all 28 calculators: formulas, assumptions, defaults, warnings, caveats, and data vintage where applicable.
For educational and informational purposes only. Not financial advice.
Example equation
Enterprise value = sum of forecast free cash flows discounted by WACC + discounted terminal value.
Formula
Each calculator page exposes the high-level equation or method used for the result.
Assumptions
Inputs and derived values stay visible so a reviewer can see what drives the output.
Defaults
Where a calculator starts with defaults, the page labels them as defaults instead of hiding them in the interface.
Warnings and caveats
Calculator pages surface invalid states, method limits, and data vintage where that context applies.
Mobile companion apps

Start with a calculatorQuestions
Before you begin.
What can I use mittafin for?
Use the calculator library for valuation, return, debt, real estate, operating, and corporate-finance questions.
What should I check when cash is tighter than profit?
Start with working capital and operating cash flow. They help separate a healthy profit figure from money tied up in invoices, inventory, or near-term bills.
How can I estimate what my business is worth?
Use a cash flow forecast and a discounted cash flow model for a grounded estimate, then compare it with an EBITDA multiple or recent market evidence where that is relevant.
Can I model a loan payment before I borrow?
Yes. The interest calculator lets you examine payment amounts, total interest, and the amortization path before you accept a loan or change its terms.
How do I compare projects with different timing?
Use net present value and internal rate of return alongside the project assumptions. They put cash received at different times on a comparable basis.
How can I pressure-test my plan?
Run a sensitivity analysis around the assumptions that matter most, such as growth, pricing, margins, financing cost, or an exit multiple.
Which return measure should I use?
Use ROI for a simple gain-versus-cost view, money-on-money for cash returned per dollar invested, and IRR when the timing of each cash flow changes the decision.
Is mittafin free during early access?
Yes. The calculator library is free to use during launch and early access. Its outputs are educational tools, not financial advice.
