Job Loss Financial Runway Calculator

How long your savings last without income.

Calculate how many months your savings will last after job loss at your current monthly spending. Enter emergency fund to see months of runway.

What this tool does

This calculator estimates how many months your savings will sustain your current spending level if you lose income. It divides your total accessible savings—combining your emergency fund and other liquid savings—by your monthly spending to show the duration your funds can cover living expenses. The result illustrates your financial runway: the time available before savings are depleted. The calculation assumes spending remains constant throughout the period; reducing expenses would extend the runway further. The tool also models the monthly income threshold needed to preserve your remaining savings, helping you understand what income level would stabilize your position. This is a straightforward model for scenario planning and does not account for investment returns, borrowing capacity, or changes in spending patterns over time.

Disclaimer

Results are estimates for educational purposes only. They do not constitute financial advice. Consult a qualified professional before making financial decisions.

18,000 in savings at 3,000/month spending = 6 months runway. Cut monthly to 2,200 (essentials only) and runway stretches to 8.2 months. Most job searches in professional roles take 3-6 months; senior roles can take 6-12. Emergency fund adequacy is the single most useful indicator of financial resilience after income loss.

Run it with sensible defaults

Using emergency fund of 18,000, other accessible savings of 0, monthly spending of 3,000, the calculation works out to 6.0 months. The defaults are meant as a starting point, not a recommendation.

The levers in this calculation

The inputs — Emergency Fund, Other Accessible Savings, and Monthly Spending — do not pull with equal force. Not every input has equal weight. Adjusting one input at a time toward extreme values shows which ones move the result most.

How the math works

Total savings divided by monthly spending. Assumes spending stays constant — reducing spending extends runway.

Spreading the cost

Starting earlier always costs less per month than starting late. That's the main lever this tool surfaces. Whatever the total, dividing it by the months until the event gives a monthly target that's easier to build into a budget.

What this doesn't capture

Life events generate side costs the figure doesn't include: time off work, lost income, travel for others, aftercare. Add 10–15% to the direct number as a buffer; the items you haven't thought of usually fill most of it.

Related calculations worth running

Plans get firmer when you triangulate. Alongside this one, the emergency fund calculator, the fire number calculator, and the bereavement financial calculator tend to come up in the same conversations. Running two or three together exposes inconsistencies in any single assumption — which is usually where the useful insight lives.

Worked example: income loss scenario

A professional earner has accumulated 24,000 in emergency savings and 8,000 in other accessible savings (total 32,000). Monthly essential expenses—rent, food, utilities, insurance—total 2,500. Using these figures, the calculator shows a runway of 12.8 months. If the same person reduces discretionary spending (dining out, subscriptions, entertainment) and brings monthly outgoings down to 2,000, the runway extends to 16 months. This additional breathing room can shift the difference between a forced decision and an informed one.

Common scenarios where this matters

  • A job search extending beyond the typical timeframe due to industry conditions or role specificity
  • A redundancy or contract ending with no immediate replacement role identified
  • A career transition or retraining period where income is interrupted
  • A household where one income earner loses employment while the other continues
  • Assessing whether to accept a lower-paying role or continue searching

What this result shows and does not show

The calculator illustrates how long liquid savings cover current spending patterns. It does not account for income from part-time work, freelance activity, or support from others. It does not model investment growth or losses on savings held in marketable securities. It does not include potential changes to essential costs (e.g., health expenses that spike during stress). It treats spending as flat; in reality, some people spend less when income stops, while others face one-time costs they hadn't anticipated.

This tool is for educational illustration only. The estimate depends entirely on the accuracy of the figures entered. Actual experience will vary based on individual circumstances, local conditions, and choices made during the income loss period.

Example Scenario

With £18,000 in emergency savings and £3,000 in monthly spending, your financial runway extends to 6.0 months.

Sources & Methodology

Methodology

The calculator computes your financial runway by dividing total accessible savings by your monthly spending rate. Total savings combines your emergency fund and other accessible savings balances. The result represents the number of months your current savings can sustain your stated monthly spending before depletion. The model assumes spending remains constant throughout the period and that all savings are equally accessible without penalty or delay. It does not account for income from any source, investment returns or losses, changes in spending patterns, taxation, fees, or the time value of money. The calculation provides a simple linear projection and should be treated as a baseline estimate rather than a precise forecast of financial sustainability.

Frequently Asked Questions

How many months runway is enough?
Standard advice is 3-6 months. Single-income households, specialised careers, or volatile industries benefit from 6-12 months.
What about reduced spending?
Most households can cut 20-30% quickly (eating out, subscriptions, discretionary). Running this tool with essential-only spending shows your 'stretched' runway.
Does redundancy pay count?
Add it to emergency fund if expected. Statutory minimum is modest; enhanced packages can be substantial depending on tenure.
Can credit cards extend runway?
Only in the short term. Financing expenses on cards creates debt that outlasts the unemployment period. Use only as last resort.
